Option H39 Mode Parameters
Table 2-1 shows the nine S-parameters and their relationship to the
ports selected.
When the analyzer is in dual- or quad-channel mode, uncoupling the
channels uncouples channels 1 and 3 from channels 2 and 4. Channels 1
and 3 cannot be uncoupled from each other. Channels 2 and 4 cannot be
uncoupled from each other. The uncoupled channels indicate the selected
port S-parameter on the display. Under the Meas menu, the active
channel shows the S-parameters that can be measured.
The Option H39 can be controlled in a number of different ways using
the 3 PORT mode. The following information is provided as a guide on
how to control the analyzer in this mode:
• through the front panel menus
• through GPIB commands
