Selecting Switch Power

After the coaxial switches have been installed (refer to “ Installing Switches on the HP E1369A” earlier in this chapter), the correct operating voltage must be selected. See installed switch specifications.

The Microwave Switch modules are capable of providing +5V (set at factory) or +12V using the mainframe power supply, or external voltages of up to 42Vpk can be connected. Determine the required operating voltage and proceed as instructed below. Refer to Figure 2-5 as required.

Caution MAXIMUM CURRENT. 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.

Internal Power Verify that the F3 fuse (P/N 2110-0712) is installed. Position jumpers as instructed:

∙For 5V, jumper JM2 installed, and jumper JM151 removed.

∙For 12V, jumper JM151 installed, and jumper JM2 removed.

External Power Verify that the F3 fuse (P/N 2110-0712) is removed (unsolder if necessary). Connect the positive lead to EXT B+ on TB1, and the negative lead to EXT GND on TB1. Connect leads to external power supply. Observe polarity.

Caution MAXIMUM VOLTAGE. The maximum voltage that may be applied to the EXTernal POWER terminal is 42Vpk.

∙Maximum wire size is No. 16 AWG. Wire ends should be stripped 6 mm (~ 0.25 in.) and tinned to prevent single strands from shorting adjacent terminals.

∙It is recommended that each channel wire be identified (color coded or marked) as the connection is not visible when the Microwave Switch module is installed.

∙Verify that wires make good connections on screw terminals.
