Turn on the FG. The ON/OFF button is in the lower left.
Wait 20 secs for it to boot and clear the display.
Enable the Output by pushing the Output Button located near lower right.
Set for High Z. Press Utility, Output Setup, High Z, and Done.
Set for desired Frequency, Amplitude, and Dc Offset.
Amplitude Frequency Response
The Agilent 33220A FG may be used to obtain the amplitude frequency response of a
two port network in conjunction with the Agilent 34401A Digital Multimeter. Connect
the input of the circuit to the output of the FG and the output of the circuit to the input of
the DMM. The output of the circuit should be monitored with a scope to make sure that it
doesn’t clip, oscillate, or severely distort. The programs assume that the gain or
magnitude of the transfer function, viz. the amplitude frequency response, is the ac
voltage measured by the DMM divided by the rms value of the voltage produced by the
FG. Either LabVIEW or VEE may be used. These programs should always be the chosen
when phase plots are not needed because the phase plots require the scope which is
slower and less accurate.
