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.
