6 Remote Control – Commands
In the following, all remote-control commands for the function groups GSM400/850/900/1800/1900-MS
will be presented in tabular form with their parameters and the ranges of values. The chapter is organ-
ized in analogy to the reference part for manual operation (chapter 4).
•
The measurement modes Non Signalling and Signalling are presented separately.
•
Within the measurement modes, general configurations (Connection Control) and the individual
measurement groups are des c ribed separately.
•
Command and measurement groups that are identical in both test modes (WPOWer, NPOWer,
POWer:SLOT,...,IQIF , symbolic status register evaluation) are presented in a separate section be-
tween the two test modes.
General notes on remote control in the function group GSM400/850/900/1800/1900-MS can be found in
chapter 5. An introduction to remote control according to the IEEE 488.2/SCPI standard is given in
chapter 5 of the CMU200/300 operating manual.
Connection Control (Non Signalling only)
In the Non Signalling mode, a GSM-specific RF signal can be generated and an RF signal with GSM
characteristics analyzed. No signalling parameters are transferred.
The remote-control commands presented in this section determine the RF analyzer and trigger settings
and the signals generated by the CMU, the inputs and outputs used as well as the reference frequency.
They correspond to the settings in the popup menu of the softkey
Connect. Control , located to the right
of the headline of each main menu.
Subsystem LEVel (Input Level)
The subsystem LEVel controls the level in the RF input signal path. It corresponds to the table section
Input Level in the Analyzer tab of the Connection Control menu.
