Release 1.171 (Jan 2023)

  • Firmware version 58 for both QA402 and QA403
  • More QA404 code added
  • Fixed regression where model wasn't being saved on close
  • More cleanup on Filter Visualizer. This still has a way to go as the graph display is too busy.
  • Removed the Bartlett window and replaced with Blackman-Harris
  • Name of settings file is shown on app title bar
  • Added N+D measurement (Noise and Distortion). Normally, noise does include distortion components. The existing N-D measurement captures the RMS energy of the noise minus the distortion productions (aka known as "just the noise"). The added N+D measurement captures the RMS energy of the noise AND distortion components.
  • Added ability to export captured data as WAV (File-Export->Export as WAV). This can be useful if you want to export a captured waveform and then load it into different analysis software for comparison.
  • Fixed bug where user weighting wasn't loading upon startup even though it would be indicated on the display.
  • Added PC Mirroring. See Edit-> Settings to enable. The "Freq/Amp Pause (mS)" setting allows you to set the amount of time to pause after the QA40x app changes the frequency and/or amplitude of Gen1. The mirroring only works for Gen1 settings, and if Gen1 is enabled. So, if you enable mirroring in the settings file, set Gen1 to -10 dBV and 1 kHz, and then enable Gen1, you should hear a 1 kHz tone coming from your primary PC sound card at -10 dBFS. Amplitudes in excess of 0 dBV are clipped to 0 dBFS when mirroring on the soundcard. With the addition of Mirroring, there are now 3 sources that can introduce a pause between acquisitions. First is the settling of relay. This is hard-coded based on the hardware. The second is the user setting (Edit->Settings) "Pause Between Acquisitions" (aka User Pause). This setting can be useful if you are testing a high-powered amp with a thermally limited load and you wanted to limit the duty cycle. And finally, the the Mirror pause. The Mirror pause delay will most often manifest in the automated test. So, if the DAC isn't settled to the new freq and/or amplitude before the measurement starts, you can bump up the Freq/Amp pause for the mirroring. The pause that occurs before the new acq starts after a freq/amp change will be the longest of 1) hardware relay changes, 2) User Pause and 3) Mirroring.
