Can someone clear up something for me. Why does the Rigol DS1054Z not allow measurements on its
math waveform ? Its just another waveform in memory.
For example I was trying to verify the filter function 3 db point after filtering a channel with LPF and
cannot make any measurements, cursor, or left hand column standard measurements, like Pk-Pk
on the math waveform, etc..
I tried cursor measurement, it only works on the 4 primary channels. You can do a pk-pk thru a contortion
of setting source channel to same scaling as math channel, then move the cursors around. But what you really
are doing is measuring the source channel screen plot.
Another suggestion for Left hand standard measurements, a db Pk-Pk, Vavg, Vrms measurement referenced to 1 V.
