I’ve found strange behavior of the system in configuration setting of 50kHz maximum waveform frequency. Attached worksheet is the log of my calibration experience.
After the “Device reference calibration” with 50KHz max. freq., warning message “Failed to achieve the specified voltage” was popped up at each switching action if “Auto_adjust_amplifier_gain” check was OFF.
Measured amplifier output voltage by DropBot is lower than actual.
On the other hand with “Auto_adjust_amplifier_gain” check was ON, higher output voltage than setting was found. It seems to be caused from miss reading of output voltage by DropBot.
These behavior isn’t found after 20kHz max. frequency calibration. So as a work around, I’m using the system calibrated with 20kHz maximum calibration even in the higher frequency operation.
I’d like to have your advise. Is there any miss understanding in my calibration steps?
