N2272A 1 GHz RF 1-to-9 MUX Module
The Agilent N2272A is a 1 GHz RF 1-to-9 Multiplexer well suited for use
in RF test and measurement applications. Seven channels are standard
branch channels. One channel, CH08, has smaller insertion loss and
lower VSWR and can be used either as standard branch channel or an
auxiliary channel.
Using the auxiliary channel, CH08, multiple N2272A modules can be
cascaded to form larger RF multiplexers while minimizing performance
degradation. For example, by connecting CH08 to the COM of a second
N2272A, a 17:1 multiplexer can be configured. Adding another N2272A
to channel 8 of the second N2272A allows a 25:1 multiplexer to be
configured, and so on.
Only one channel can be closed at a time. The Agilent N2272A does not
support the OPEN command (one channel must always be closed).
Closing a channel opens any other closed channel.
Note The Agilent N2272A can only be used with the SCPI Mode of 3499
Firmware Revision 3.0 or later. See page 59 for details about the
firmware revisions.
Specifications for the N2272A are given on page 323.
