Installing Switches on the HP E1369A
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.
Installing Switches
on the Module
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.
Note 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).

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.
