I was able to add a meas by sending the below cmd which defaults to CH1.  
self.inst.write('MEASUrement:addmeas pduty')

How do I change the source to CH2? I have tried a few things, 2 which are as shown below. 
Also, how do I check "show stats badge" and turn population limit on to 100? see below also. 
  
self.inst.write('MEASUrement:addmeas pduty:CH2')
self.inst.write('MEASUrement:CH2:addmeas pduty')
def limit_population(self, N=100):
    self.inst.write('MEASUrement: POPUlation:LIMIT: ON')
    self.inst.write('MEASUrement: POPUlation:LIMIT: VALue ' + str(N))

Hello,

  • To measure from other channels, you should first select it using this command below(for example) before running the MEAS:addmeas command.

DISPLAY:SELect:SOUrce CH2

DISPLAY:SELect:WAVEViewx:SOUrce CH2

  • To check the "show stats badge" and change the limit to 100, please use these commands replacing x with whichever measurement number you want to adjust the population limit for.

MEASUrement:MEASx:DISPlaystat:ENABle ON

MEASUrement:MEASx:POPUlation:LIMIT:STATE ON

MEASUrement:MEASx:POPUlation:LIMIT:VALue 100

Hopefully this helps.
