Hello Scopers,
I have an 'old' MSO8104A. Running firmware 05.50.0001.
I am trying to automate a measurement of the delay between two rising edges on channel 1 and channel 2.
Currently I am using the square ave from the calibration spigot to feed Chan1 and Chan2 and have the scope setup and triggered. I can manually make the measurement - as exepceted the time delay between the two is ~0 (in the ns noise region).
The problem I have is the measurements does not seem to return a valid result when I query the measurement.
I send the following:
:meas:define DELT,RISING,1,MIDD,RISING,2,MIDD
*wai;*opc?
:meas:deltatime? CHAN1,CHAN2
Imagine my disappointment when return value=9.99999e+37 (invalid measurement)
Please can someone let me know what I am missing? I can make simple single source measurements but am struggling with this one.
Thanks
andy

I had a typo in:
:meas:define DELT,RISING,1,MIDD,RISING,2,MIDD
which should have been:
:meas:define DELT,RISING,1,MIDD,RISING,1,MIDD
Scope could not fnd a 2nd edge on Chan2 hence the rightful e+37 return.
Sorry for the wasted post.....
