3.7.1 LD Source Function
Syntax
SOURce[1]:FUNCtion:MODE {CURRent|POWer}
SOURce[1]:FUNCtion:MODE?
SOURce[1]:FUNCtion[:SHAPe] {DC|PULSe}
SOURce[1]:FUNCtion[:SHAPe]?
Description
The
SOURce[1]:FUNCtion:MODE
and
SOURce[1]:FUNCtion[:SHAPe]
commands set the
instrument's LD source function to constant current (CW) mode or to pulsed constant current
(QCW) mode or to constant power (CW) mode.
Note
The combination
POWer
and
PULSe
is not available.
Example
SOUR:FUNC:MODE CURR;SHAP DC
Sets the LD source function of a LDC4000 Series or an ITC4000 Series instrument to
constant current (CW) mode.
SOUR:FUNC:MODE?;SHAP?
Queries the LD source function.
CURR;DC
Response for constant current (CW) mode or
CURR;PULS
response for pulsed constant current (QCW) mode or
POW;DC
response for constant power (CW) mode.
Note
This command is valid for LDC4000 and ITC4000 Series instruments only.
3.7.2 LD Current Limit
Syntax
SOURce[1]:CURRent:LIMit[:AMPLitude] {MIN|MAX|<amps>}
SOURce[1]:CURRent:LIMit[:AMPLitude]? [{MIN|MAX}]
SOURce[1]:CURRent:LIMit:TRIPped?
Description
The
SOURce[1]:CURRent:LIMit[:AMPLitude]
command sets the LD source limit current in
amperes.
The
SOURce[1]:CURRent:LIMit:TRIPped?
query command returns an ASCII
1
if the LD
source current reached the limit value or an ASCII
0
if it’s inactive.
Example
SOUR:CURR:LIM 1.5
Sets the LD source limit current to 1.5 A on a LDC4000 Series or an ITC4000 Series
instrument.
