This adjustment calibrates the LF Output path on the A11 Pulse/Analog Modulation Generator for an accurate output voltage.
During this adjustment, the source LF Output is connected to a DVM. One of the two internal modulators on the A11 Pulse/Analog Modulation Generator is set for a 1 kHz, 1 V-peak sinewave. The internal path is switched so that the modulator output is routed to the LF Output. A DVM reading is taken, the DAC is set to the new value, the LF Output voltage is measured to verify the adjustment, and calibration data is stored.

Setup for Low Frequency Output Calibration
If this adjustment fails, perform the following steps in order:
Check the equipment setup (see above). If the setup is incorrect, make the necessary corrections and rerun the adjustment.
If this adjustment fails with the equipment set up properly, refer to the troubleshooting section of the signal generator's service guide. If you do not have a printed copy of the service guide (Option OBW), one is available either on the CD-ROM that came with your signal generator shipment or on the Keysight Website.
If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
