What are you using for input conditioning?
The Omron LDS I am using includes an amplifier (Z4M-W40RA). I think that is what you mean. Details on it can be found here: http://www.omronkft.hu/pdf_en/z4m.pdf
I am also using a regulated DC power source as recommended to power the LDS. -

It says that the output is 4 to 20mA/30 to 50mm, and that it is adjustable from 3.2 to 20.8mA with the Span adjustment. So you can play with that to maximize the signal going into the DAQ. That's where an oscilloscope would come in handy. However, the DI-145 is designed for voltage input not current input. Do you have a terminating resistor across + to - at the input of the DAQ to convert current to voltage? That will affect the scaling too. They have DAQ's that accept current input directly, which would be best IMO.

To put things into perspective, the maximum displacement of the beam during the last test was ~0.12volts. If TT and rfmwguy's estimate of 0.216volts/mm is close to mine, then the measurements we are taking occur over a distance of 0.55mm.
How much of the input range of your ADC is 0.12V ? What is the width of the output of the ADC, 8 bits, 10 bits, 12 bits, 16 bits ? If the ADC takes in 0-5V full scale and is 8 bits output then that could explain that your experiment is recorded on the 3 or 4 least significant bits only (between 8 or 16 discrete levels). Sorry if this is documented in some previously linked data.
There has to be at least 8 bits in the output at max. amplitude because digitization is barely visible. If there were 8 bits all on at the max amplitude (assuming a unipolar A/D) and bit 4 was stuck off there would be 7 spots in the waveform where it would be flat. Depending on the slope and noise level the width of the flat spots would vary. This is close to what I see in the graph. For N A/D bits at max amplitude it could be bit N-4 that is stuck. Somewhere around there. It could be a loose wire or, if the A/D data is transmitted serially there may be a strange software bug. A/D defects are not very common today. In 1978 when I worked for Digilab in Cambridge MA we used hybrid modules from Analogic (maybe it was Analog Devices) that had a 4 figure price tag. Their A/D kit (3 small boards) was the only guaranteed monotonic 13 bit A/D on the market. When you try to do an FFT on data that has a stuck bit or is not monotonic the result is mostly artificial noise. The picture is from EE247 Lecture 12 of the eecs department at UC Berkeley.

Jamie has a 250 ohm and I have a 270 ohm loading resistor. Factory calls for 300 ohm max to be within linearity specs. Found offset adjustment works best setting min at 0.6V and span to abt 6V max. That varies based on displacement. On my long beam I have more displacement to work with. Its a basic 10 bit ADC but seems to do the job.What are you using for input conditioning?

The ADC output in Monomorphic's test P11 is granular as might be expected. The difference between consecutive measurements is always an exact multiple of 10/8192 volts, or 10/(2^13).
The values tend to 'stick' every 16 such units (once in a while every 20), or every 10/512 volts.
One observation is that the Volatility appears suppressed during power on. 51% of all consecutive transitions are zero with power-on, compared with only 40% overall and 36% during power-off. I think that is statistically significant, but I'm not sure.
Monomorphic - I note that the RF column in your table goes back to close to zero for some time in the middle of what you have designated as power on (in fact in the section where most of the beam movement occurs). Is that real or just some quirk in the data? -

That's how I send events to the ADC. It's simply a battery and wireless manual switch. Each time I turn it off or on, that registers as an event with a vertical line. First click on is for RF on, second click off is for 2.46Ghz, third click on is for 2.45Ghz and final click off is for RF off. -

One of the cooling methods that were researched on cooling the magnetron other than just in air with the cooling fins on the magnetron tube.
Panasonic Pyrolitic Graphite Sheets
Pricing is not bad.
https://www.google.com/#q=Panasonic+Pyrolytic+Graphite+Sheets&tbm=shop
http://www.digikey.com/product-search/en?vendor=10&keywords=panasonic+pgs
I figured you could use a magnetron you had disassembled and the aluminum fins as a template, make larger ones or anyway it's easy. Attach the pyrolytic sheets to the larger cooling fins. My quick on a napkin calculations showed that extending the cooling fins only 4 inches on the open sides with the pyrolitic sheets attached you could keep the magnetron stable and cool for extended runs. FWIW
Just an idea and didn't work out all the details but could be easy to figure out.

A little over a year ago, I conjectured that the EM Drive was a type of warp drive because gravity is related to dissipation and attenuation. I wrote and published a paper called the The Electromagnetic Quantum Vacuum Warp Drive that showed exactly how gravity is related to the available driving power from the ZPF, but it didn't really talk much about dissipation or attenuation. Just that the available power was a variable.
Well, I'm now finishing up a new paper that shows without a doubt, that gravity is the result of increased local energy density CAUSING increased radiative damping within the harmonic oscillations that make up all matter. The ZPF is the driving power that inflates matter, and radiative damping is the loss of power that causes gravitational length contraction and time dilation. Matter in an inertial frame is in equilibrium between the source and sink of this power. Essentially then, gravitational acceleration is caused by asymmetrical variations in radiative damping. Not only did the math fall out beautifully such that it could easily be understood how this could be misinterpreted as space-time curvature. It also shows the Planck force acting on a sphere with a Planck length radius, is EQUAL to the force on the Hubble sphere, with the Hubble radius. I find this very interesting, because why should these two extreme length scales be related in any way unless one is derived from the other? I show that it is!
In any case, you all can gather what this implies. That if this EM Drive thing moves without ejecting any momentum, this is why! It is asymmetrical damping and attenuation creating a gravitational effect within a limited bandwidth of the EM spectrum. DeAquino's ideas of using ferro metal at the small end may indeed be the ticket to higher thrust, because it will cause a greater asymmetry in the dissipation taking place in the shell of the frustum.

Simply put, the Hubble constant says that the length of a 1 meter object on Earth has been shrinking linearly as matter cools and condenses, at a rate of 6.9 nm/century, relative to the light emitted by distant stars in the distant past, when the universe was in a hotter, more inflated state than it is here and now

WarpTech, isn't your hypothesis easily testable? You should be able to detect a force generated on external object when the frustum is powered up, yes?
If the device produces any gravitational effect at all, aside from being astounding, it would be a gravity wave generator. If it can produce an asymmetrical wave pattern, such as a cardioid, it would be a device that always slides downhill. An Escher engine! -

Maybe. At this stage however, the only evidence I have is the same evidence that supports General Relativity, i.e., gravitational lensing, time dilation, length contraction, perihelion of Mercury, etc... The same experimental data that supports GR also supports my model with the added benefit that my model fits well within the Standard Model of Quantum Electrodynamics, where GR does not.
It doesn't radiate a gravitational field as you put it though. The gradient is internal and only over a limited RF bandwidth. So it isn't going to affect material outside the frustum. It will affect the material of the frustum because it is being excited at the RF frequency and damped by the heat in the metal and the asymmetrical attenuation of the cavity.
As for showing radiative damping can create propulsion, I don't have any predictions right now that can be tested. Maybe in the next paper, in a year or two.

Well, I'm now finishing up a new paper that shows without a doubt, that gravity is the result of increased local energy density CAUSING increased radiative damping within the harmonic oscillations that make up all matter.
That increased damping as light falls into a gravitational well is what causes its red shift I assume which is like the light changing in mass? Is it similar to condensation of mass from the ZPF on the photon or other matter slowing it's osculations down or making time slow down? If so is this a parallel to some change in the mass of light such that when the light strikes the narrow end of the cavity it is more efficient at exchanging energy with that side of the cavity leading to a non-equilibrium between strikes with each side. Giving the cavity over time an acceleration in the direction where light is heavier. Such exchanges I expect to actually drain the light of its energy if the cavity is allowed to freely accelerate (if there is thrust from the light in the cavity).The ZPF is the driving power that inflates matter, and radiative damping is the loss of power that causes gravitational length contraction and time dilation. Matter in an inertial frame is in equilibrium between the source and sink of this power. Essentially then, gravitational acceleration is caused by asymmetrical variations in radiative damping.

I was referred to this article here by otto: http://arxiv.org/abs/1603.07224 his post here: https://forum.nasaspaceflight.com/index.php?topic=39772.msg1548704#msg1548704
Basically when the light enters a medium the light changes in mass some how (possibly from the zpf). This mass is moving with the light and the light is slowed by this increase in mass. The balance in momentum gives the medium a kick when the light enters. (what if this medium is the zpf?) After the light enters a high index medium having slowed down it strikes a mirror and it appears the light is more efficient at transferring energy to a reflector (actual experiment shows this). I did some math on this earlier and was able to show that if the mass of light can change it can change the percentage of energy exchange from an impact. The math here: https://forum.nasaspaceflight.com/index.php?topic=31037.msg1494279#msg1494279 This percentage of energy exchanged by light to an object accelerated on an impact governs the Doppler shift and I was able to derive the Doppler shift from it. The Doppler shift is even different if it is from an emission or a reflection because the two are different in energy exchanged. The math here: https://forum.nasaspaceflight.com/index.php?topic=31037.msg1497641#msg1497641
So how does this apply to the cavity? Well if the mass of light increases at one end of the cavity it can give more energy to one side of the cavity and if the cavity accelerates the light starts Doppler shifting till the energy runs out. I suspect the kick when light enters the more dense medium is what is accelerating the vacuum. That is in the cavity some how the density of the ZPF being more dense is receiving a kick as if it were the high index material. However the ZPF can pass through the cavity. Hopefully my terminology is not too far off here.
What keeps it from accelerating to infinity? Nearing light speed the cavity would perceive the heavier light as losing energy so eventually there is a equilibrium reached where the light striking the narrow end appears equal in mass to the light striking the big end and there is no more imbalance in energy exchange upon impact.
Basically this allows a photon recycling thruster but inside a cavity (if it works) which is mind boggling. I am just tossing at you some ideas I have been thinking about which may be parallels to what your talking about. What do you think?
I almost want to say it might have implications to a Woodward effect as well.
This may also explain why increasing the dielectric constant of a dielectric inside the cavity doesn't necessarily increase the thrust. i.e. the dielectric is receiving a kick back but it is attached to the cavity. The objective being to increase the effective dielectric constant of the vacuum itself for a particular frequency.
Edit 1: I have substituted the full derivation in the image below. I thought the one in the link for the % energy exchanged was a bit flawed and corrected it. This one seems correct.

How would you answer to the following argument against any useful interaction with the Quantum Vacuum:
Virtual particles in the Quantum Vacuum (for example electron-positron pairs) that fluctuate into and out of existence violate energy conservation and so must be governed by the Heisenberg energy-time Uncertainty relation.
That limits their fluctuational lifetimes to 3 X 10-22 sec.
As of May 2010, the smallest time interval uncertainty in direct measurements is on the order of 12 attoseconds (1.2 × 10−17 seconds). (See: http://phys.org/news/2010-05-attoseconds-world-shortest.html ). In the visible domain, a single oscillation of the electric field takes about 1200-2500 attoseconds, which is 154 times longer than this. And that is in the visible domain (not in the GHz domain of the EM Drive, which takes several orders of magnitude longer).
So the smallest time interval uncertainty in direct measurements is about 40 000 times longer than the time of the QV fluctuational lifetimes.
Another comparison: the atomic unit of time is 24 attoseconds (https://en.wikipedia.org/wiki/Atomic_units) (the fastest possible time scale of processes in the outer shells of an atom) which is 80 000 times longer than the maximum possible lifetime of virtual pairs from the Quantum Vacuum.
This life-time (of virtual pairs in the Quantum Vacuum) is so short ( 3 X 10-22 sec) that it seems impossible to transfer anything to/from a given virtual pair before it vanishes. To do anything useful with such a Quantum Vacuum, it would need to have a gigantic density.
If you calculate how large that density would need to be, it is so large that it would have been detected long, long ago. [We discussed this previously, for example with Dr. Notsosureofit] So something like a microwave cavity operating at GHz of small dimensions with energy input of less than 1kW seems quite unlikely to be able to detect such a huge density that has not been previously detected, by much more sophisticated means of detection.

My paper doesn't deal with this question. However, the question itself is posed from the viewpoint that matter is not already interacting with the ZPF. In my model, I make it clear that the scale of matter is set by a uniform ZPF, throughout the universe, as a cosmological constant. If the ZPF possessed higher power, then matter would inflate and the universe would appear smaller. If it were lower power, then matter would contract and the universe would appear larger. The ZPF is the driving source of energy, it's like the battery or the source of energy. It sets the Maximum ground-state energy in matter.
Radiative damping is the resistor in the RLC circuit. It is what causes space-time to vary according to the mass-energy density in the local region. It's a velocity potential, just like gravity. The radiative damping function for a free electron in flat space-time, meaning far from any other source of mass-energy density and that just the ZPF and the electron are present. Results from the Radiation Reaction, of the electron reacting to it's own field. This value comes from the Abraham-Lorentz equation and the Larmour Power formula. It's value is
6.334 x 10-24 s
A much smaller number than the life-time you referenced. As the electron approaches a gravitational mass, the time between interactions decreases from here. The rate of interaction therefore increases. The Neper Frequency goes up. The generalization of this is that as the number of interactions goes up, the particle spends less time in resonance with the ZPF, its oscillation is damped and it's frequency decreases, as in the case of an underdamped oscillator. Lower frequency means a slower rate of time passing, fewer ticks on the clock.
As for the question and the argument against interacting with the vacuum. IMO, the vacuum is a dielectric insulator. If there are electron-positron pairs being created, then there is dielecric breakdown of the vacuum. It should not happen except in the presence of the strong electric field surrounding a charged particle, where virtual pairs are known to exist. So in that regard, I don't think that these hiesenberg pairs are created out of nothing. What fills the void is an electromagnetic ZPF, that has a high frequency cut-off at the point where matter becomes transparent to those frequencies and it can no longer interact with it, which is just below the point where dielectric breakdown would occur.
Regarding that last part there on the EM Drive. What is going on only mimics gravity over a narrow bandwidth. It's not interacting with the vacuum. It's interacting with itself. It is a resonant cavity. If it were symmetrical, I would not expect any acceleration to result, but given that dissipative systems do not need to conserve momentum because heat loss is a random momentum transfer, AND it is asymmetrical....

So why there is not more thrust than for a photon rocket using a simple (50 Ohm)load and a HF source, if we look to the attenuator only? (Where normally total net-thrust is zero because of radiation and attenuation in such a closed(hypothetical perfect) system is equal)....

What fills the void is an electromagnetic ZPF, that has a high frequency cut-off at the point where matter becomes transparent to those frequencies and it can no longer interact with it, which is just below the point where dielectric breakdown would occur.
Regarding that last part there on the EM Drive. What is going on only mimics gravity over a narrow bandwidth. It's not interacting with the vacuum. It's interacting with itself. It is a resonant cavity. If it were symmetrical, I would not expect any acceleration to result, but given that dissipative systems do not need to conserve momentum because heat loss is a random momentum transfer, AND it is asymmetrical....

Edit: added last para.
I'm being very careful to be concise and check my work thoroughly. Anyone willing to referee my paper and give me some feedback before I finalize, send me a PM and I'll forward the draft to you. It's not ready yet, but almost...
