Low Frequency (LF) Output Calibration

Description

The LF output provides a calibrated audio frequency signal. This test is used to set the

full-scale amplitude of the LF-OUT DAC on the reference board. When the calibration is

complete, the voltage on the LF output should be equal to the input voltage, plus or minus

1 mV. The resulting DAC values are then stored in the signal generators ﬁrmware.

Required Test Equipment

• HP/Agilent 3458A Digital Multimeter
