Step 4. Channel 2 input offset voltage calibration adjustment
1. Install a triaxial shielding cap on the channel 2 INPUT connector.
2. Send this command to calibrate channel 2 input offset voltage:
:CAL:PROT:SOUR2:OFFS
Step 5. Channel 2 voltage source calibration adjustment
Follow these steps to calibrate the channel 2 voltage bias source.
summarizes
channel 1 calibration voltages and commands.
1. Connect the DMM to the Model 6482 channel 2 OUTPUT and INPUT LO terminals, as shown
in
2. Select the DMM DC voltage function, and enable autorange.
3. Send this command to turn on the channel 2 output:
:OUTP2 ON
4. Send the following command to select the channel 2, 10 V voltage bias range:
:SOUR2:VOLT:RANG 10
5. Send the following command to 10 V:
:SOUR2:VOLT 10
6. Note and record the DMM reading, and send that value as the parameter for the following
command:
:CAL:PROT:SOUR2 <DMM_Reading>
