Command Descriptions
NOTE
. Some commands are described in groups in which all of the command
headers in the group begin with the same keyword or keywords. Commands
within the group are described by referring to their final keyword or keywords.
Complete commands are formed by combining the beginning keyword(s) and the
final keyword(s), using the usual ‘:’ separator. For example, if a command has
the beginning keywords of CONFigure:BSTation and final keywords of FRE-
Quency:SELect , the complete command header is: CONFigure:BSTation:FRE-
Quency:SELect
The same method can be used to form command headers when the keywords of
the header are broken into more than two parts.
This section divides the remote commands into different groups, listing the
commands in each group and describing them in general terms. The command
set can be divided into several categories: common commands that are required
by the IEEE and SCPI standards; status reporting commands, also required by
these standards; and device specific commands unique to the tester. The device
specific commands set up and release calls with the mobile station under test,
configure the tester hardware (both in general and in connection with specific
tests), set test parameters, and run and return results from predefined tests of the
mobile station.
Refer to Appendix D: Remote Control Command Table for a listing of all
commands and more information about each command than is given in this
section. Included are argument ranges, default values, the instrument state or
states when the command may be used, and programming notes.
NOTE
. When operating the tester from the front panel, many predefined tests can
run continuously, either in all cases or as the result of a mode selection.
However all tests are run in the single-shot mode in remote operation. A test
normally runs to completion and reports its results; however, in tests that require
a substantial amount of time (for example, 20 seconds), the user may select for
the test to terminate early if the tester detects that the test failed.
Common commands, also known as device independent commands, are not
specific to the tester, but rather are specified for all instruments in the
IEEE 488.2 standard and/or the SCPI standard. All common commands begin
with the character ‘*.’
The common commands in the tester are: *CLS, *ESE and *ESE?, *ESR?,
*IDN?, *IST?, *OPC and *OPC?, *OPT?, *PRE and PRE?, *PSC and *PSC?,
*RST, *SRE and *SRE?, STB?, *TST?, and *WAI. The operation of these
commands is described in Appendix B: Remote Control.
