13.6 SOURce Group
The commands in this group deal with setting the source function (voltage, current, thermocouple, RTD, resistance),
setting the main setting, setting the reference junction compensation, and creating user-defined thermocouples and
RTDs. The commands correspond to the front panel RANGE dial, TEMPERATURE dial, and main setting dials and
the SCALE switch.
:SOURce?
Function
Queries all source settings.
:SOURce?
Syntax
:SOURce:FUNCtion
Function
Sets or queries the source function.
:SOURce:FUNCtion {VOLTage|CURRent|
Syntax
TCouple|RTD|RESistance|RJTemp}
:SOURce:FUNCtion?
VOLTage: Voltage
CURRent: Current
TCouple: Thermocouple
RTD: Resistance temperature detector
RESistance: Resistance
RJTemp: Reference junction temperature
(reference junction compensation value)
:SOURCE:FUNCTION VOLTAGE
Example
:SOURCE:FUNCTION? -> VOLTAGE
Description If the front panel is displaying the SETUP menu,
"NONE" will be returned in response to a query.
:SOURce:LEVel[:AUTO]
Function
Sets or queries the main setting for main setting
(MAX) or main setting (MIN), whichever is
selected.
:SOURce:LEVel[:AUTO]
Syntax
{< Voltage >|< Current >|
< Temperature >|< Resistance >|MINimum|MAXim
um}
:SOURce:LEVel[:AUTO]?
<Voltage>: Voltage
<Current>: Current
<Temperature>: Temperature
<Resistance>: Resistance
MINimum: Minimum value in the selectable
range*
MAXimum: Maximum value in the selectable
range*
* See "Description."
:SOURCE:LEVEL:AUTO 10V
Example
:SOURCE:LEVEL:AUTO?
-> :SOURCE:LEVEL:AUTO 10.0000E+00
13-8
13-8
Description 1. Even if you include the plus or minus sign in
the setting with this :SOURce:LEVel[:AUTO]
command, the polarity will not be set. The
polarity follows the setting specified by the next
command. The minimum and maximum values
are also set to the absolute values of the
minimum and maximum values for the polarity
side set by the next command.
:OUTPut:POLarity[:AUTO]
:OUTPut:POLarity:MAXimum
:OUTPut:POLarity:MINimum
2. To set the value with the sign, use the
:SOURce:SLEVel[:AUTO] command.
3. Before setting <Voltage>, use the
:SOURce:FUNCtion command to set the
source function to VOLTage.
Before setting <Current>, use the
:SOURce:FUNCtion command to set the
source function to CURRent.
Before setting <Temperature>, use the
:SOURce:FUNCtion command to set the
source function to TCouple or RTD.
Before setting <Resistance>, use the
:SOURce:FUNCtion command to set the
source function to RESistance.
If you set a main setting of a different source
function, a "131: Invalid suffix" error will occur.
4. If the source function is RJTemp and you set
the main setting, a "221: Setting conflict" error
will occur. 9.91E+37 is returned as a response
to a query.
5. The selectable range changes depending
on the range setting of the voltage, current,
or resistance or the type setting of the
thermocouple or RTD. Set the voltage, current,
or resistance range with the :SOURce:RANGe
command. Set the thermocouple or RTD type
with the :SOURce:TYPE command.
6. If the resolution mode is set to HIGH, the
main setting can be set only when the source
function is set to VOLTage or CURRent.
Another digit is added to the resolution.
