SCXI-1120/D Calibration Procedure
6.
Connect the DMM to the output of the same channel to which the
calibrator was connected in step 5. Refer to Figure 4 to determine the
pins on the 50-pin rear connector that correspond to the positive and
negative outputs for the specified channel. For example, the positive
output for channel 0 is pin 3, which is labeled
MCH0+
. The negative
output for channel 0 is pin 4, which is labeled
MCH0–
.
