CALIBRATION USING REMOTE SCPI COMMANDS VIA GPIB OR RS 232 INTERFACE

The primary means of adjustment are the CAL:DATA commands. Basically these commands
are fine and coarse adjustments, however there are slight differences in how they work for dif-
ferent types of calibrations.
a. ZERO Calibrations (always done first). The only means of adjustment is the
CAL:DATA <VALUE> command which provides a total of 4095 increments of adjustment start-
ing at 0, with 2047 increments in either direction to achieve maximum output levels of ±2.5% of
E . Adjust the output to obtain the closest value to zero.
Onom
b. MAX and MIN Calibrations. The primary means of adjustment is the CAL:DATA <VALUE>
command to either increase (CAL:DATA 1) or decrease (CAL:DATA -1) the output value.
Adjustment can be done in larger increments by increasing the numeric value, e.g.,
CAL:DATA +10 or CAL:DATA -10. Adjust the output to obtain the closest value above the full
scale value.
c. VPR and CPR Calibrations. The only means of adjustment is the CAL:DATA <VALUE>
command which provides a total of 4095 increments of adjustment from zero to maximum.
Adjust the output to obtain the closest value above the full scale value.
