------------------------- I recently bought a PSG9080 and noticed the output voltage settings did not seem very accurate. Since my most accurate instrument is a 40,000 count DMM, I wanted to check the calibration of the PSG9080 against it. I thought the most accurate way to do this would be to use the DC "waveform" so it wouldn't involve any inaccuracies in measuring RMS of a sine wave. But when I set the PSG9080 to DC, I found that the amplitude control did not change the DC level. I had to use the offset control to change the DC level. I did not like that because the offset setting only has 10 mV resolution rather than the 1 mV resolution of the amplitude control. Have you seen this?
Do you think the Brands Labeled on the FY6900 Units really matter - I have seen FEEL-TECH,FEEL ELECTRONIC,KMOON and other Brand Names marked on the units
Is that duty cycle setting common to all modes where setting duty cycle does make sense or not? E.g. if you set duty cycle to 20% in ramp mode, does this also propagate to duty cycle in another modes (like PWM)?
Thanks, I'm looking forward to the further testing/comparisons you've outlined ... especially with the SDS1032X.
He said "Duty".

The noise with 10 mVpp - 20 mVpp is very high
Does this accept a 10MHz input clock standard?

I haven't checked all modes but it appears to be common in those I have checked.
@@tomtektest8042 Ok, this behavior makes sense. Thank you for testing this.
