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))
