I use USB cable to control MSO58B (software ver:2.4.4.1152) through pyvisa.  Here is my code:
............
self.scope.write('MEASUREMENT:CH2:REFLEVELS:METHOD ABSOLUTE')   

I checked the Meas1-->Reference Levels-->Set Levels in .  It still show '%'.   I checked the program mannual of MSO5B and can not get more information.

who can help to tell me how to change Meas1-->Reference Levels-->Set Levels in -->Absolute ?

thanks

Hi Cheng,

I would suggest trying MEASU:MEAS1:REFL:METHOD absolute
