Valid Gain Adjustment Input Values; Ac Voltage Low Frequency Gain And Flatness Calibration - Keysight Technologies DAQ970A Service Manual

2 Calibration Procedures

Valid gain adjustment input values

Gain calibration can be accomplished using the following input values:
[a] Valid frequencies are nominal frequencies ±1%.
