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".
