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
