Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 16: SCPI Command Reference
Query :TRIGgered? Query triggered amplitude for fixed source
:TRIGgered? DEFault Query *RST default amplitude
:TRIGgered? MINimum Query lowest allowable amplitude
:TRIGgered? MAXimum Query highest allowable amplitude
Description These commands perform the same as the [:IMMediate][:AMPLitude] commands
except that the source amplitude is not updated immediately.
With this command, the amplitude is updated when the Model 6482 is triggered to
perform a source and measure operation. For example, if the instrument is waiting
in the trigger layer for an external trigger, the amplitude of the source will not
update until that external trigger is received by the Model 6482. See
Section 8 ,
“Triggering,” for details on trigger model operation.
The MINimum and MAXimum parameters are only valid if the 30 V source range
is presently selected. Sending the MINimum or MAXimum parameters on the 10 V
source range will generate error -221 (Setting Conflict).
Set delay
NOTE
All SOURx:DEL commands are global and affect both simultaneously.
DELay <n>
:SOURce[1]:DELay <n> Manually set source delay
:SOURce2:DELay <n> Manually set source delay
Parameters <n> = 0 to 999.998 Specify delay in seconds
MINimum 0 seconds
MAXimum 999.998 seconds
DEFault 0.001
Query :DELay? Query delay
:DELay? DEFault Query *RST default delay
:DELay? MINimum Query lowest allowable delay
:DELay? MAXimum Query highest allowable delay
Description This command is used to manually set a delay (settling time) for the source. After
the programmed source is turned on, this delay occurs to allow the source level to
settle before a measurement is taken. Note that this delay is the same for both
channels.
Do not confuse this source delay with the trigger delay. The source delay is part of
the device action (SDM cycle) while the trigger delay occurs before the device
action. See
Section 8 , “Front-panel operation of the trigger model,” for more infor-
mation.
Autodelay can instead be used to automatically set the source delay. See the next
command.
AUTO <b>
:SOURce[1]:DELay:AUTO <b> Enable or disable automatic source delay
:SOURce2:DELay:AUTO <b>
Enable or disable automatic source delay
Parameters <b> = 0 or OFF Disable autodelay
1 or ON Enable autodelay
Query :AUTO? Query state of autodelay
