All,
I am using an E4443A PSA to make occupied bandwidth measurements. Setting up the measurement is not a problem, however I can't figure out how to read back the result.
Can anyone tell me the SCPI command(s) I need to accomplish this? Please see attachment.
Thanks,
Bill

The following is from page 57 of the "User’s and Programmer’s Reference
Volume 2
One-Button Power Measurements
PSA and ESA Series Spectrum Analyzers"
The publication number is E4440-90346 which may be found by direct search using the number in the search field on the home page www.agilent.com.
Each measurement personality has its own programming manual, which can be confusing at times. The core programming manual contains basic spectrum analyzer functions that are more or less contained in the IVI SA class.
The power measurements such as ACPR and channel power are in what we call the power measurement suite even though it is standard in all PSA's.
Sincerely yours,
Brent

Remote Command:
Remote Command Notes: The results for both values are returned in Hz.
Example: FETC:OBW? or MEAS:OBW? or READ:OBW? command returns scalar results
of occupied bandwidth and transmit frequency error.
FETC:OBW:FERR? or MEAS:OBW:FERR? or READ:OBW:FERR? commands will
return the single scalar result specified.
