44476B Microwave Switch Module
The 44476B is not supplied with microwave switches. You must provide
your own microwave switches, mount them on the assembly, and connect
one of the module’s Form C relay drive circuits to each switch.
The 44476B panel has two 53.8 X 9.6 mm cutouts for a set of microwave
switches. The recommended Agilent microwave switches are listed
below.
The 3499A/B/C identifies this module as a 44471A on the front-panel
display. Changing the state of channels other than channels 00 through
02 does not generate an error, but has no effect.
Specifications for the 44476B are dependent upon the switches used.
Refer to the switch data sheets for more information.
