DC Function Offset Verification
This test verifies the DC offset and DC output specifications.
Set the function generator for each output indicated in the table below.
Use a DMM to measure the function generator dcV output. Compare the
measured results to the test limits shown in the table. This is a HIGH Z
output termination test.
Agilent 33120A Measurement
Function OUT TERM 1Ampl Nominal Error
QDC Volts HIGH Z 10.0 Vdc 10.0 Vdc 0.20 Vdc
DC Volts HIGH Z -10.0 Vdc -10.0 Vdc 0.20 Vdc
AC Amplitude VerificationThis procedure is used to check the output amplitude calibration of the
function generator. Verification checks are performed to check the
accuracy of the pre-attenuator and post attenuator. Make sure you have
read “Test Considerations” on page 53.
Set the function generator for each output indicated in the table on the
next page. Use a DMM to measure the ACrms output voltage of the
function generator. Compare the measured results to the test limits
shown in the table. This is a HIGH Z output termination test.
1Output termination set using front panel controls. HIGH Z assumes no load on
output. 50W assumes a 50W 0.1W load on output.
