Analog Bus ADC Calibration
Description
This test is used to calibrate the gain of the ABUS. The ABUS is connected to the ground
node (ACOM) and the ADC is zeroed. The ABUS is then connected to the 10 V reference
and measured. The result of the measured value divided by the ideal value is the ABUS
gain calibration constant. This value is then saved in the signal generator’s firmware.
Required Test Equipment
• HP/Agilent 3458A Digital Multimeter
