Analog Output Verification Test
calibration of the analog outputs on the 34951A 4-channel DAC Module.
Verification checks are performed only for those output values with unique
calibration constants.
1 Using the input test connector described on

3 Set each output voltage value in the table below and make a measurement.
It is not necessary to test the voltage output at the full rated 10 mA load. If you

test the output using a load, connect the sense terminals.
4 Make current measurement connections to channel 1 of the module. Set the

terminal open. Set the DMM to the 100 mA range. Make and record a current
measurement. This value will be used as an offset value during the output
current zero verification.
Compare measurement results to the appropriate test limits shown in the
table.
DMM to the 100 mA range.
Compare measurement results to the appropriate test limits shown in the
table. When measuring the 0 mA output value, apply the offset value from
step 1 to the measured value.
