The communication-related subsystems
These subsystems cover system relevant tasks, which are not primarily involved in the measurement process.
SYSTem
– System parameters, such as the number of unread error messages, the test set's GBIP address etc. may
be read out or set using the commands of this subsystem.
STATus
– The STATus subsystem controls and provides information on the state of the 2201R. There are two types
of states: operational states describe what is currently going on within the test set while questionable states deliver
questionable states of the 2201R.
FORMat
– The commands of this subsystem enable settings of the data output format in remote mode.
The SYSTem subsystem
System parameters, such as the number of unread error messages, the test set's interface parameters etc. may be read
out or set using the commands of this subsystem.
The STATus subsystem
The STATus subsystem delivers detailed information about the internal status of the 2201R, its error conditions and
special events. These three areas are dealt with in three different sections of the status subsystem. These three
sections are addressed, using different commands.
The status subsystem provides in-depth information about the internal status of the test set. Furthermore, powerful
event processing tools allow any form of flexible control over the 2201R Mobile Tester.
However, the use of the status subsystem is a little complicated because of the many parameters involved. Therefore,
we suggest you carefully read subsection
’Understanding the STATus subsystem’ on page 25
before using the status
subsystem.
A table of all registers implemented can be found in subsection
’Table of registers’ on page 27
Understanding the STATus subsystem
The STATus subsystem is intended to deal with special events occurring inside the test set. It provides tools to enable
any current condition to raise a system event.
There are several groups of registers, structured in a hierarchical order.
Lower-level registers work on specific conditions and single parameters while higher-level registers integrate the
result of several lower-level registers and thus provide a more general view.
The highest level of these registers is the service register, sometimes also referred to as the status byte register or
status byte.

Area
Related commands
Main functional aspects
Operation
Status
STATus:OPERation...
These commands deal with the operation
status of the 2201R. They describe what is
currently going on inside the test set, mainly
in respect of signaling and measuring.
System
Errors
STATus:QUEStionable...
This area of the internal status report system
mainly deals with errors and warnings
regarding the hardware stages of the 2201R
(like 'RF input overload' or 'frequency out of
range'.
Execution
Errors
*ESE, *ESR?
Mainly program or SCPI command
execution errors are dealt with in this area of
the internal status report system.
