OUTPut2

 

:ATTenuation <attenuation>

 

:IMPedance <impedance>

 

:OVERload?

[query only]

[:STATe] <mode>

 

:ACTual?

[query only]

OUTPut2 is the root keyword of the command, :ATTenuation, :IMPedance, :OVERload?, and [:STATe] are second level keywords, and :ACTual? is the third level keyword. A colon (:) always separates a command keyword from a lower level keyword as shown below:

OUTP2:STAT:ACT?

A semicolon (;) is used to separate two or more commands within the same subsystem, and can also save typing. For example, sending this command message:

OUTP2:IMP 50;OUTP2:ATT 6;OUTP2:STAT ON

is the same as sending these three commands:

OUTP2:IMP 50

OUTP2:ATT 6

OUTP2:STAT ON

A semicolon (;) and a colon (:) are used to separate two or more commands from different subsystems in the same command message. For example:

INP1:IMP 50;:OUTP2:IMP 50

Command Coupling The following amplifier commands are value coupled:

E1446 with E1405/06

OUTPut1:ATTenuation <attenuation>

OUTPut1:IMPedance <impedance>

SOURce:VOLTage[:LEVel][:IMMediate]:OFFSet <voltage>

E1446 with E1445

OUTPut2:ATTenuation <attenuation>

OUTPut2:IMPedance <impedance>

SOURce2:VOLTage[:LEVel][:IMMediate]:OFFSet <voltage>

This means that sending one of these commands can change the value set previously by another one of these commands. Often, this results in “Settings Conflict” errors when the program executes. To prevent these errors these commands must be executed in a "coupling group".
