I have a DSO4202c with software version 3.50.0(190325.0).

If I put it in Average mode when looking at a 21 MHz sinewave, the amplitude "flutters".  I think this is a software bug because I don't recall that it di this before I upgraded the firmware to 190325.0.

Other settings
   sec/div: 40.0 ns
   Type: Real Time
   volts/div: 5.00V
   input: on Ch.1

Hi wjw,

Did you pereformed an upgrade to a new firmware? In my case the upgrade didn't help.

Regarde, Sead
