Programming An Output Rf Spectrum Measurement; Example Program - Agilent Technologies 8960 10 Series Reference Manual

Programming an Output RF Spectrum Measurement

This section provides an example of how to make the output RF spectrum (ORFS) measurement via GPIB.
The following procedure assumes that an active link is established between the test set and the mobile station.
See "Establishing an Active Link with the Mobile Station" on page
1. Configure the ORFS measurement parameters using the SETup subsystem.
2. Start the ORFS measurement using the INITiate subsystem.
3. Use the INITiate:DONE? command to find out if ORFS measurement results are available.
4. Use the FETCh? command to obtain ORFS Power measurement results.

Example Program
