N2276B Microwave MUX/Attenuator Module
The Agilent N2276B contains microwave switch and attenuator driver
circuits. The microwave switches or attenuators can be mounted to the
rear panel of the module or connected with an auxiliary cable for
convenience.
The N2276B is shipped without any switches, allowing for custom
configuration. Several microwave switches and attenuators are available
for use with the module.
The N2276B is a three slot module and cannot be used in the 3499B two-
slot mainframe.
Due to the drive circuitry, each N2276B causes about 0.5 second’s delay
during power up. Your 3499A/C may seem to turn on slower after you
add N2276B modules.
An 8-bit DIP switch on the module sets the configuration for the switches
and attenuators. Four connectors are located on the module; two 16-pin
connectors (labeled as switch0 & switch1) for connecting switches and
two 10-pin connectors (labeled as attenuator0 & attenuator1) for
connecting attenuators.
Note The Agilent N2276B can only be used with the SCPI Mode of 3499A/B/C
Firmware Revision 3.0 or later. See page 59 for details about the
firmware revisions.
Caution The driving circuitry of the module is capacitive. Turn off power before
installing or removing the module, switches, or attenuators.
Specifications for the N2276B are given on page 325.
