Frequency increment

Postby PhC » Wed Nov 23, 2016 11:50 am

Hello,
I have a problem with the generator of my pico 5444B. The frequency setpoint does not seem to be respected.
The signal from the AWG passes through a 2nd order low pass filter with 0.35Hz cutoff frequency. I do not understand why all frequency deviations are not equal to about 30mHz as expected (see attached document).

The problem is resolved. The value of increment in frequency was too small compared to the frequency resolution of the generator ... when I set it to 50mHz, all is ok ...
