SOURce:MODE
Syntax
SOURce:MODE <mode>, (@<ch_list>)
SOURce:MODE? (@<ch_list>)
Description
This command selects the voltage or current mode for the specified channels on the 34951A Isolated DAC Module.

Remarks
Sending the SOURce:CURRent[:LEVel] or SOURce:VOLTage[:LEVel] command will automatically enable the corresponding mode. The SOURce:MODE command gives you the capability to predefine voltage and current levels on the specified channels and then switch from one mode to the other.
If the output is enabled (OUTPut[:STATe] ON) at the time you switch modes, the output will be momentarily disabled. After the mode transition is complete, the output will be re-enabled (some settling time may occur).
If the output is disabled (OUTPut[:STATe] OFF) at the time you switch modes, the output will remain off after the mode transition is complete.
A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) will reset the module to the voltage mode. In addition, storing the instrument state (*SAV command) will reset the module to the voltage mode.
Return Format
The query command returns the present output mode: "VOLT" or "CURR". Multiple responses are separated by commas.
Examples
The following command sets a current level and a voltage level on DAC channels 1 and 2 in slot 4. The SOURce:MODE command selects the current mode.
SOUR:CURR 5E-3,(@4001,4002) !Selects
the current level
SOUR:VOLT 2.5, (@4001,4002) !Selects
the voltage level
SOUR:MODE CURR,(@4001,4002) !Switch
to current mode
The following query returns the output mode in use on DAC channels 1 and 2 in slot 4.
SOUR:MODE? (@4001,4002)
Typical Response: CURR,CURR
