AM signal generator issue on DSO4102C

DanRuderman

I ran two tests on the signal generator which are showing unexpected
behavior.

Settings of signal generator for 2 tests:
AM/FM: AM
Amplitude: 1.0V
F0: 147Hz
Depth: 0

Photo shows sudden change in waveform with F=10Hz




Photo shows step pattern in waveform with F=1Hz



Can you please explain how to fix these issues?

Thank you,
Dan

The first problem is that F0 and frequency are integer multiples, the waveform will be a smooth curve.
About the second problem, we will reply you after testing.
