N67xx DUT Power Supply Installation 1-9
Connecting to the ASRU Card
Connecting to Channels 1 through 4
The N6751 is a 4-output DUT power supply. One ASRU channel is required for each
output.
1 Locate the highest numbered module with channels 1 through 4 available on
the ASRU Card.
If channels 1 through 4 are not available, see Connecting to Channels 5 and 6
on page 1-10.
2 Connect the DUT Power Supply cable to the ASRU Card and to the N6751
power supply, as illustrated in Figure 1-5.

Connecting to Channels 5 and 6
If channels 1 through 4 are not available in any module, cable the N6751 supply to
a bank where both modules have channels 5 and 6 available. Split the outputs as
shown in Figure 1-6. Notice that output 3 goes to channel 5 and output 4 goes to
channel 6 on the ASRU Card in the higher numbered module. It is possible that
there will not be enough ASRU Card channels available to use all of the power
supply outputs. Output 1 goes to channel 5 and output 2 goes to channel 6 on the
ASRU Card in the lower numbered module in the same bank.
To connect all of the outputs, two cables are necessary since the outputs will go to
two modules. Remember to connect the banana plug ground on the back of the
power supply and the ground lug connector to the ASRU Card.
