Hi everyone

I know use command can create measurement, ex. MEASUREMENT:MEAS10 -> is create MEAS10
but I want setting Measurement source(not use default source) before ADD Measurement
I can't found any command example can setting source before create measurement in 4-5-6-Series-MSO-Programmer Manual
I want know how to use command change Measurement type and setting source in this screen(File MSO2.jpg)

Best Regards
