I am using pulse output at low frequency (100Hz) with phase modulation by noise.
The settings are : Ch.1: 100Hz pulse, 1ms width. 10V pp, +5V offset, Modulation = internal, PM, Phase dev = 10 deg, Shape = noise, bandwidth = 20Hz.
Occasionally there is an extra pulse inserted in the waveform at 180 deg, in other words a frequency doubling for one cycle. I have tried this with sine modulation, with similar results.
Is there a firmware fix available for this bug?
