This selects the rear panel AUX INPUT to drive the analog bus for voltage
and frequency measurements It can be used to look at test points within the
instrument, using the analyzer’s display as an oscilloscope. Connect the test
point of interest to the rear panel AUX INPUT BNC connector.
This feature can be useful if an oscilloscope is not available. Also, it can be used
for testing voltage-controlled devices by connecting the driving voltage of the
device under test to the AUX IN connector. Look at the driving voltage on one
display channel, while displaying the S-parameter response of the test device on
the other display channel.
