FET1854 frequency extension modules allow for measurement of the DUT S-parameters in the frequency range between 18 to 54 GHz. See the FET Operating Manual for a detailed description of the module.
The front and rear panels of the Module are shown in the figures below. The test port and ground terminal are located on the front panel. The rear panel contains a status indicator, a control cable connector, and a group of connectors for connecting the module to the Analyzer:
•Test signal (RF IN)
•LO signal (LO IN)
•IF signal of the reference channel (IF REF)
•IF signal of the test channel (IF TEST)
