SCXI-1122 Calibration Procedure
11. If you have an SCXI-1322 terminal block, connect the calibrator to the
CH0+ and CH0– inputs of the terminal block. If you are not using a
terminal block, connect the calibrator to analog input channel 0.
Refer to Table 1 to determine the pins on the 96-pin front connector
that correspond to the positive and negative inputs of the specified
channel. For example, the positive input for channel 0 is pin A32,
which is labeled
CH0+
. The negative input for channel 0 is pin C31,
which is labeled
CH0–
.
