Agilent E8462A Relay Multiplexer Command Reference 69
Linking Multiple SCPI Commands From the Same Subsystem. Use only a
semicolon between commands within the same subsystem. For example, to set the
trigger slope and the trigger source which are both set using the TRIGger subsystem,
send the following SCPI string:
TRIG:SLOPe NEG;SOURce EXT
Linking Multiple SCPI Commands of Different Subsystems. Use both a
semicolon and a colon between commands of different subsystems. For example, a
ARM and OUTPut command can be sent in the same SCPI string linked with a
semicolon and colon (;:) as follows:
ARM:COUNt 10;:OUTP:TTLT4 ON
Variable Command
Syntax
Some commands have what appears to be a variable syntax. For example:
OUTPut:ECLTrgn and OUTPut:TTLTrgn
In these commands, the "n" is replaced by a number. No space is left between the
command and the number because the number is not a parameter. The number is part
of the command syntax. In the case of
OUTPut:ECLTrgn, "n" can range from 0 to 1.
In
OUTPut:TTLTrgn, "n" can range from 0 through 7.
Parameters Parameter Types. The following table contains explanations and examples of
parameter types you might see later in this chapter.
Parameter Types The following list contains explanations and examples of parameter types you will
see later in this chapter.
Boolean Parameters represent a single binary condition that is either true or false
(for example, ON, OFF, 1, 0). Any non-zero value is considered true.
Discrete Parameters selects from a finite number of values.
These parameters use mnemonics to represent each valid setting.

Type
Explanations and Examples
Numeric Accepts all commonly used decimal representations of number
including optional signs, decimal points, and scientific notation.
123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases include MINimum, MAXimum, and DEFault.
Boolean Represents a single binary condition that is either true or false.
ON, OFF, 1, 0
Discrete Selects from a finite number of values. These parameters
use mnemonics to represent each valid setting.
An example is the TRIGger:SOURce <source> command where
source can be OFF, BUS, EXT1-2, HOLD, IMM, INT1-4 or
TTLT0-7.
