Relay Matrix Switch Command Reference 39Chapter 3
Parameter Types The following table contains explanations and examples of parameter
types you may see in this chapter.
Discrete parameters selects from a finite number of
va
lues. These parameters use mnemonics to represent
each valid setting. An example is TRIGger:SOURce
<source>, where source can be BUS, EXTernal, HOLD,
IMMediate, ECLTrgn, or TTLTrgn.
Optional Parameters are shown within square brackets
(
[]). The brackets are not part of the command and are
not sent to the instrument. If you do not specify a value
for an optional parameter, the instrument chooses a
default value. 

For example, consider ARM:COUNt?[MIN|MAX]. If you
se
nd the command without specifying a parameter, the
present ARM:COUNt value is returned. If you send the
MIN parameter, the command returns the minimum
count available. If you send the MAX parameter, the
command returns the maximum count available. Be sure
to place a space between the command and the
parameter.
Linking Commands Linking IEEE 488.2 Common Commands with SCPI Commands. Use a
semicolon (;) between the commands. For example, *RST;OUTP ON or
TRIG:SOUR HOLD;*TRG.
Linking Multiple SCPI commands. Use both a semicolon (;) and a colon (:)
between the commands, such as ARM:COUN 1;:TRIG:SOUR EXT.
SCPI Commands Reference
This section describes the Standard Commands for Programmable
Instruments (SCPI) commands for the Relay Matrix Switch modules.
Commands are listed alphabetically by subsystem and within each
subsystem.
Type Explanations and Examples
Boolean
Boolean parameters represent a single binary condition
that is either true or false (ON, OFF, 1, 0). Any non-zero
value is considered true.
Discrete
Numeric
Numeric Parameters are commonly used decimal
representations of numbers including optional signs,
decimal points, and scientific notation (for example, 123,
123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E- 01).
Special cases include MIN, MAX, DEFault, and INFinity.
Optional
