Installing a Switch or Attenuator on the HP E1370A Microwave Switch/Attenuator Card

Installing a Switch

or Attenuator on

the Module

Because the HP E1370A Microwave Switch/Attenuator modules do not have a Microwave Switch of Attenuator installed by the factory, it is necessary to install or connect a switch or attenuator before operating. Determine whether the switch or attenuator is to be installed on, or connected to, the module and proceed as instructed below.

Installation of a Microwave Switch of Attenuator is described below. Figure 2-7 shows the wiring diagram and mounting hole centers for the switch of attenuator installed.
