Alphabetical Command Reference
In this chapter, you can find an alphabetical list and brief descriptions of the supported
commands for controlling the Agilent 8703B remotely.
NOTE Some commands have a range of values associated with them. If you send a
value that is beyond the analyzer’s capability, the analyzer will default to the
closest allowed value. Refer to the individual commands for the specific range
of values allowed.
1-2
Alphabetical Command Reference
Symbol Conventions
Symbol Conventions
<num> Required numerical data.
<choice1|choice2|…|choicen> An appendage that is part of the command. For example,
FORMAT<DOS|LIF> indicates that the actual commands are
FORMATDOS and FORMATLIF.
<$> Indicates a character string operand which must be
enclosed by double quotes.
| An either/or choice in an appendage or optional data.
[ ] Optional data.
A terminator indicates the end of a command string, and this manual uses a semicolon as the
terminator in all syntax examples. The analyzer also interprets line feeds and GPIB end or
identify (EOI) messages as terminators.
Terminators are not necessary for the analyzer to interpret commands correctly, however in
the case of a syntax error, the analyzer will attempt to recover at the next terminator.
Therefore, it is recommended that you conclude each command with a terminator.
Because this chapter is an “Alphabetical Command Reference,” the commands have been
listed alphabetically, rather than by function, in both the “Syntax” sections and the
“Description ” sections. Therefore, commands grouped together in the “Syntax” sections, are
grouped alphabetically and/or due to common syntax form, not necessarily due to common
functionality.
The softkeys listed in the “Front Panel Equivalents” tables may not be in the first menu
viewed when the associated hardkey is pressed. In many cases, more than one key press will
be required to locate the softkey. Refer to your analyzer’s reference guide for the exact
location of any softkey.
Some commands that do not have an associated query syntax can be queried by sending the
command (without a value) and then sending the OUTPACTI command, as in the following
example that queries the segment power value:
10 OUTPUT 716;”SEGPOWER;OUTPACTI;”
Many of the commands that do have a listed query syntax can also be queried in this manner.

CHAN
CHAN
CHAN<1|2|3|4>;
Makes channel 1, 2, 3, or 4 the active channel. OPC-compatible. No query response.
NOTE These commands should use OPC? to prevent timing errors with subsequent
commands. Example code written in BASIC:
10 OUTPUT 716;"OPC?;CHAN2;"
20 ENTER 716;OPC

CLASS
CLASS<11A|11B|11C|22A|22B|22C>;
These commands call reflection standard classes during a calibration sequence. If only one
standard is in the class, it is measured. If there is more than one, the standard being used
must be selected with STAN<A|B|C|D|E|F|G>. If there is only one standard in the class,
these commands are OPC-compatible.
