Overview - Agilent Technologies 8960 10 Series Reference Manual

Overview

The FETCh subsystem is used to query measurement results. The measurement results from each
measurement in a test application can be queried using the FETCh subsystem. The general hierarchy of the
FETCh command structure is as follows:
FETCh:<meas-mnemonic>:<result format>?
The following table shows the measurements available in the Agilent Technologies E1960A GSM mobile test
application and their associated <meas-mnemonic> used in the FETCh command syntax.
The command syntax used to obtain the various measurement result formats (<result format>) for each
measurement can be found in the test set's FETCh? subsystem's GPIB command syntax reference
information.
Example 1. Command Syntax:
FETCh:<meas-mnemonic>:<result format>?
Example 2. Programming Example:
OUTPUT Test_set;"FETCh:TXP:POW:MIN?"
would return the minimum value from the set of samples taken during the transmit power measurement
(when averaging is turned on and number of samples taken >1).
