Got the burst measurements uploaded from memory using the GPIB interface.
The commands have to be issues in a specific manner when doing this manually.
Set instrument range eg 0.1v
Clear the memory history
Set up the instrument to trigger in burst mode - set no. samples required.
Set the GPIB to ++auto 2
send TRI to start the burst mode.
Set to ++auto3
Send Du (DUmp memory contents)
Send ++Read
memory contents are loaded into the serial monitor screen.
Graph below.
Sample rate is 1Khz, the sine wave period is 30ms or 33hz
I did the same on Range 1 and range 10, but the signal is very "digitised" so not very helpful but is a similar but 'blocky shape'.
Would be interesting to see what your instrument shows Grizewald, performing the same test

So that is something to think about.
Next I'll swap out the ICL7650 and do the same test.
