Operating instructions

R&S ESCI SOURce Subsystem
1166.6004.12 6.199 E-1
SOURce:EXTernal Subsystem
The SOURce:EXTernal subsystem controls the operation of the unit with option Ext. Generator Control
(B10). The commands are only valid for the selected window, with SOURce1 changing the setting in
screen A and SOURce2 the setting in screen B.
The selection of the external generator 1 or 2 is via EXTernal<1|2>.
Note: The commands of the SOURce:EXTernal subsystem assume that the addressed generator
was correctly configured with the commands of subsystem
SYSTem:COMMunicate:GPIB:RDEVice:GENerator.
If no external generator is selected, if the IEC bus address is not correct or the generator is
not ready for operation, an execution error will be generated.

Ext. generator option
SOURce<1|2>:EXTernal<1|2>[:STATe] ON | OFF
This command activates or deactivates the external generator selected with
SOUR:EXT<1|2>:FREQ:SWE ON in the selected window.
The suffix behind EXTernal is irrelevant for this command.
This command is only available in connection with option Ext. Generator Control B10.
Example: "SYST:COMM:RDEV:GEN1:TYPE 'SMP02'"
'Selects SMP02 as generator 1.
"SYST:COMM:RDEV:GEN1:LINK TTL"
'Selects IECBUS + TTL link as interface.
"SYST:COMM:RDEV:GEN1:ADDR 28"
'Sets the generator address to 28.
"SOUR:EXT1:FREQ:SWE ON"
'Activates the frequency sweep for generator 1.
"SOUR:EXT ON" 'Activates the external generator
