Keithley 6482 - Set Amplitude for Fixed Source

16-42 Return to Section Topics 6482-901-01 Rev. A / August 2012
Section 16: SCPI Command Reference Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Query AUTO? Query state of autorange
Description These commands are used to enable or disable autorange for the specified
source. When enabled, the instrument will automatically select the most sensitive
range for the specified source level. When disabled, the instrument will use the
range that the instrument is currently on.
Autorange will be disabled if a fixed range is selected. See the previous com-
mand.
Both *RST and :SYSTem:PREset enables source autorange. When the
Model 6482 goes into the local state, source autorange disables.
Set amplitude for fixed source
[:IMMediate][:AMPLitude] <n>
:SOURce[1]:VOLTage[:LEVel][:AMPLitude] <n>Set fixed source 1 amplitude
:SOURce2:VOLTage[:LEVel][:AMPLitude] <n>Set fixed source 2 amplitude
Parameters <n> = -30 to 30 Set source amplitude (volts)
DEFault 0 V
MINimum -30 V
MAXimum 30 V
Query :VOLTage? Query programmed source amplitude
:VOLTage? DEFault Query *RST default amplitude
:VOLTage? MINimum Query lowest allowable amplitude
:VOLTage? MAXimum Query highest allowable amplitude
Description This command is used to immediately update the amplitude of a fixed source.
This command is not valid if the list or sweep mode is selected.
NOTE The sourcing :MODE command is used to select a fixed source. See “Select sourcing
mode,” page Section 16-40.
If a manual source range is presently selected, then the specified amplitude can-
not exceed that range. For example, if the source is on the 10 V range (autorange
disabled), you will not be able to set the source amplitude to 20 V. In autorange,
the amplitude can be set to any level that is within the capabilities of the source.
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).
