Can the PSG9080 do (constant frequency) AM and frequency sweep at the same time?

No, modulation mode and sweep mode are different modes and available on separate screens.

I'm wondering, what you're trying to do with AM modulation in sweep mode?  ???

Hello!!

I just beginner in electronics.

I also bought JUNTEK PSG9080 in DEC 2020. I wanna pass out triangle signal to op amp but with external voltage offset by another op amp (both op amps are powering by external 9V BAT->3.3V LDO->OP AMPS). Then I connect GEN_GND (just GND without output !) to my offset amp then oscilloscope start display offset voltage with some noise component. My offset op amp produce 100 mV signal. If I try power generator from classical supply with 50 Hz transformer can it help me keep my 100 mV signal in clear?

Also I have another question about this generator - can I use it for getting amplitude-frequency response diagrams ? I saw sweep mode but can't synchronize gen output with "in X" on oscilloscope(( Does it really possible with such equipment?


Thanks all for answers !!

If the sweep does not provide a sync output, maybe instead you could FM modulate one channel by the other.
