I posted a few months ago on this scope.

I was not able to get this resolved at the time and got busy on other projects.

I want to take a fresh look at it now.

Here is an example of what I am seeing.

Using a function generator with 50 ohm termination, frequency set to .5 MHz, volts 4.0 peak to peak- out of the function generator.

If sending a square wave the scope will auto measure the voltages corectly.

Example;

peak to peak 2.02 volts
pos peak 1.01
neg peak 1.01

If I change to a triang. wave. (frequency and voltage the same) the scope will now not measure the voltages correctly.

Eample;

peak to peak 1.1 volts
pos peak .97 volts
neg peak .14 volts

If I measure manually using the cursers, they are correct.

I verified the trigger cal. and did a DC balance.

Please help.

Thanks, B
