Example: Multiple

Channel Switching

using EXTernal

POWER

This example illustrates closing and opening coaxial switch channels 00
through 04 in a HP E1369A Microwave Switch Driver module. For the
example, the switches are not installed on the HP E1369A card, and have
24Vdc drive requirements (HP 33311B or 8762B). Figure 3-4 shows how
to connect an external power supply to the EXTernal POWER terminals to
provide the necessary 24Vdc drive for the coaxial switches, and how to
connect the 14-pin cable to the external switches.

To close channels 00 through 04, execute:

CLOS (@100:104)

Connect channels 00, 01, 02, 03,
and 04 switch port 2 to port C, and
terminate port 1 into 50; 1 is the
card number and 00-04 are the
channel numbers.

To open channel 00 through 04, execute:

OPEN (@100:104)

Connect channels 00, 01, 02, 03,
and 04 switch port 1 to port C, and
terminate port 2 into 50; 1 is the
card number and 00-04 are the
channel numbers.
