Installing Switches on the HP E1369A

Installing Switches on the Module

Note

Because the HP E1369A Microwave Switch modules do not have Microwave Switches installed by the factory, it is necessary to install or connect switches before operating. Determine the number of switches, and whether the switches are to be installed on, or connected to, the module and proceed as instructed below.

Installation described for up to three coaxial switches (channels 00-02) is below. Figure 2-3 shows the wiring diagram and mounting hole centers for each switch installed.

HP SWITCHES. The following 5V HP 333XX series and HP 876X series switches will function in the HP E1369A Microwave Switch module.

The corresponding HP 876X and 333XX series switches shown in the table below are electrically and physically identical. The HP 8761, 8766 (33363), 8767 (33364),8768 (33365),8769 (33366) series coaxial switches will not function in the HP E1369A Microwave Switch module because the switch coils are not split (separate for each contact).

33314B/011 or 8765B/005/100	DC to 20 GHz	50Ω	3	No ports	No	B
33314C/011 or 8765C/005/100	DC to 26.5 GHz	50Ω	3	No ports	No	B

NON-HP SWITCHES. K&L Microwave Inc., Dynatech Microwave Technology Inc., and RLC Electronics Inc. currently manufacture split coil coaxial switches that will physically mount in the HP E1369A Microwave Switch module rear panel. All switches mount using the "A" hole centers (see Figure 2-3). When selecting switches, refer to the diagram shown in Figure 1-1 to verify that the switch will electrically function in the HP E1369A Microwave Switch module. Remember, switches must have split coil operation with 42V maximum drive level.

Caution The maximum current that the control circuit can accommodate is 1 amp per switch. Maximum current also depends on the output capacity of the mainframe or power supply used.
