4.4.2 SCPI Commands
The 2400/2500 SCPI commands are divided into subsystems. The following sections describe the
2400/2500 SCPI commands, and are organized according to subsystems.
4.4.2.1 SCPI Commands; Output Subsystem
Table 8
Output Subsystem SCPI Commands
Command Syntax
Description
OUTPut[:STATe] ON|OFF|1|0
Turns the signal at the RF OUT connector on or off.
OUTPut[:STATe]?
Queries the RF OUTPUT state. The return value is as
follows:
1
The signal at the RF OUT connector is currently on.
0
The signal at the RF OUT connector is currently off.
4.4.2.2 SCPI Commands; Source Subsystem – CW Mode
All commands in the Source subsystem begin with [SOURce]; however, [SOURce] is the default
command, which is optional.
Table 9
Source Subsystem – CW Mode SCPI Commands
Command Syntax
Description
[SOURce]:FREQuency[:CW|:FIXed] <freq> [HZ |
KHZ | MHZ | GHZ]
Sets CW frequency to the value specified by
<freq>. The units are assumed to be in Hertz if no
unit designator is supplied.
[SOURce]:FREQuency[:CW|:FIXed]?
Queries the current CW frequency. The value
returned is in Hz.
[SOURce]:MODE CW|FIXed|LIST|FSWEep
|PSWEep
Sets the operational mode of the synthesizer:
•
CW or FIXed is used to set the source to
output a non-swept signal.
•
LIST is used to set the source to use LIST mode.
•
FSWEep is used to set the source to frequency
sweep.
•
PSWEep is used to set the source to power
sweep.
[SOURce]:MODE?
Queries the current operating mode of the
instrument.
