HP E1370A VXI Microwave Switch/Step Attenuator Driver

Product Summary

The HP E1370A switch/step attenuator driver is a B-size, 2-slot, register-based VXI module. It provides room for you to install a single-pole multithrow microwave switch or a programmable step attenuator.

The HP 8766/7/8/9K single-pole, multithrow switches can be installed, providing 3-, 4-, 5-, or 6-throw switching. Alternatively, the HP 33320G/H, 33321G/H, 33322G/H, and 33323K step attenuators can be installed providing broadband accuracy, high repeatability over a long life, and rapid switching flexibility. Whichever device you choose, you must order each one separately.

This module contains the control, drive, and power circuitry for mounting and controlling the microwave switches or step attenuators. Additionally, it comes with a 14-pin DIP socket for connecting one microwave switch or step attenuator either in the module or remotely.

Cabling
For frequencies up to 18 GHz, use a good quality flexible cable and SMA connectors. For frequencies above 18 GHz, use semirigid type cable and APC 3.5 connectors.

C-size Adapter
For installation in a C-size mainframe, see the HP E1403B active adapter.

Product Features

• Switching and attenuation up to 26.5 GHz
• Drive any HP 8766/7/8/9K microwave switch
• Drive any HP 3332XG programmable step attenuator
