GPRS signalling (with option CMU-K42)
The structure of chapter 6 differs from chapter 4 (Functions and their Applica-
tion) where the measurements are presented first and special configurations are
reported at the end of each signalling mode section.
The menu of the graphical user interface corresponding to a group of com-
mands is quoted at the beginning of each section. Lists of all commands (by
function and alphabetical) are annexed to chapter 6.
SCPI Conformity In view of the particular requirements of GSM measurements not all commands
could be taken from the SCPI standard. However, the syntax and structure of all
commands is based on SCPI rules. For a detailed description of the SCPI stan-
dard refer to chapter 5 of the CMU operating manual.
Remote Control
All commands may be used for control of the CMU via GPIB and serial (RS-232)
interface.
Measurement Control
The commands in the measurement groups
WPOWer, NPOWer, POWer..., MODulation...,
SPECtrum...,
and
RXQuality...
have an analogous structure and syntax. The measurements are
controlled according to common concepts which are explained in detail in Chapter 5 of the CMU operat-
ing manual. The following sections show how the general concepts are applied to GSM-MS measure-
ments.
Measurement Groups
The measurement groups are referred to as measurement objects (keyword <meas_obj>) in remote
control. Most measurement objects correspond to a measurement group or application in manual con-
trol. For GSM measurements, the following measurement objects are defined:
