Analog Output Adjustments

The following analog output adjustment procedures are to be performed following a 1 hour warm up period.

This procedure results in the L4451A setting a zero adjustment and a gain adjustment constant for each DAC output. You must perform all the adjustments on one analog output channel before adjusting the other analog output channels. The procedure can be aborted at any time using the command:

CALibration:ABORt (@<channel>)

Each of the four DAC channels is calibrated separately for voltage and current. A DMM capable of measuring up to ± 12V and ± 22 mA is required. A calibrated 6.5 digit DMM is recommended.

There are 88 calibration points required to calibrate the voltage and current on all four DAC channels, so automation of the procedure is highly recommended.
