Here-attached is the Virtins Multi-Instrument PSF (Pannel Settings File) I created for the measurements above.
This is optimized for 1920 x 1080 resolution, with automaticaly hidden Task Bar (to allow an easy screen snapshot export)
Voltage measurements are foreseen to cover most of my measurements scenarii.
They have to be entered manually.
(I do it automatically through .Net automation though)
I manually drag the relevant DMM (Digital Multi Meter) Voltage measurement to the Dashboard area, according to the test scenario.
(here we see it for a DAC measurement)
NB: You may get the Voltage from the ADC level, if the signal shape is matching a sine wave (which you may check using the Crest factor measurement, just below the generator window - typically, it works above -50dBFS), but you should NEVER use the DAC dBFS level to guess the voltage, since it will vary with the load impedance.
In the bottom right, you'll find the "standard" SINAD, THD and SNR measurements.
(ie the ones computed on a much narrower fundamental frequency bandwidth)
Note that THD figures are the same. The difference lies in the SNR.
Also note that, as you may read in posts above, SNR and SINAD are also giving the exact same figures when the APU notch is not used.
Behind the Signal Generator (top right), you may find more measurements (essentially Noise Levels) using both methods.
I use Dolph-Chebyshev 200 to match AP's proprietary window function.
But since I always tune frequency to avoid spectral leakage, "Rectangle" (ie "NO") window function gives the exact same results.
Note that I'm using the AES-17 standard 997Hz frequency for tests.
This allows the 20th harmonic to show in the THD and THD+N (SINAD) results.
I tuned the APU accordingly.
EDIT: I forgot to mention that, to use the APU notch, you need to select a corresponding compensation file, in the "Spectrum analyzer" configuration screen.
I first performed a measurement of the notch with REW, then converted the data to the right format with Excel and saved it in the compensation file.
This is a one shot operation.
If requested, I may describe this process in details.
RE-EDIT: The Panel Settings file was optimized for "Hot Panel Settings Toolbar"
disabled
You may uncheck it in the "Setting" menu.
Some DDPs (measurement values) will show in front of the generator window.
You may either close them or just click on the generator window to push them behind.
The PSF file requires 24 DDPs, which is the maximum number available since Multi-Instrument version 3.9.6.1
I now use 3.9.6.2 (latest to date)
Questions and comments are, of course, welcome.
