Microwave Switch/Attenuator Driver

34945A Microwave Switch/Attenuator Driver

The 34945A consists of a plug- in driver interface module (34945A) and
one or more external remote modules (34945EXT). The first remote
module is electrically attached to the driver module using a provided cable
(equipped with 9- pin D- Sub connectors). The first remote module attached
to the driver module is referred to as the

master

module. Any additional

external remote modules are referred to as

slave

modules.

Additional remote modules (34945EXT) are connected in a daisy- chain
fashion using RJ- 45 connectors and cables. A cable is provided with each
additional remote module. Up to eight remote modules can be controlled
by a single 34945A and up to eight 34945As may be installed in a 34980A
mainframe. However, the maximum number of 34945EXTs allowed per
mainframe is eight in any configuration.

Each remote module is divided into four banks for switch control.
Each bank has a connector for a distribution board. The distribution
boards provide an electrical connection between the user- supplied
microwave switches or attenuators and the remote module. A variety
of distribution boards are available that provide the most common
connections to Agilent microwave switches and attenuators. A screw
terminal distribution board is also available for other devices. A list of the
available distribution boards is shown on

page 224

. The microwave

switches or attenuators and the cables connecting them to the distribution
boards are not supplied with the 34945A.

The cables and the remote modules allow the microwave switches and
attenuators to be located closer to the device under test. This helps to
keep the signal transmission paths shorter and corresponding signal
losses lower.

Microwave switches and attenuators have larger power requirements than
other switch devices. In many cases, the 34980A mainframe is able to
power 24 Volt switches or attenuators on the first remote module (master).
Any additional remote modules (slaves) require an external power supply
since no power is supplied through the expansion bus cable. The first
remote module may use either an external power supply or the mainframe
power to supply high power devices or devices requiring drive voltages
other than 24 Volt. Each remote module has screw terminals for the
external power supply connections.
