Operation - Option H39 Parameters
“3 PORT” Mode
Firmware revisions 8753E 7.60, 8753ES 7.60 and above give the
analyzer new functionality, making it easier to control the port states of
the Option H39 test set. When the instrument is shipped, Option H39 is
visible in the option field of the display and the 3 PORT mode is turned
on. With the 3 PORT mode on, the port status can now be controlled
through the Meas key and the SELEPORT GPIB commands. To turn off
the 3 PORT mode, follow the System menu in Figure 2-2. Toggle the
3 PORT MODE key from ON to OFF. With the 3 PORT mode off, the
functionality of the analyzer is the same as earlier versions of the
firmware and is backwards compatible. To reactivate the Option H39
features, toggle the 3 PORT MODE key to ON. See Figure 2-3, “Meas Key
Menu Map,” “Option H39 Mode Parameters” on page 2-8, and
“Option H39 Mode GPIB Commands” on page 2-12. Other keys in the
Option HXX Config menu are not active. If the keys are pressed, the
message OPTION FUNCTION; NOT INSTALLED will appear.
