Q: I'm having troubles getting a useful response from a measurement command. The result is zero all the time, for every type of measurement. Here's the setup:
Inject a 10kHz 4Vp-p sine wave from a signal generator into a TEK MSO5204B on channel 4. Use SCPI commands to turn on CH4 and put the scope in "RUN" mode.
Send these SCPI commands:
MEASUrement:MEAS1:SOUrce CH4
MEASUrement:MEAS1:TYPE FREQUENCY;ACQUIRE:STATE ON
MEASUrement:MEAS1:VALue?
The scope's measurement setup page will show Frequency as measurement number 1 on CH4
The query returns the following result:
:MEASUREMENT:MEAS1:VALUE 0.00000000000 FREQ
I can parse out the value easily enough but the value should be 10 kHz, not zero.
A: the solution is to turn on the measurement state, with the commands:
:MEASUrement:MEASx:SOUrce CHchannel;
