DC Routes

The output multiplexer can make the route between a

pogo pin and the SYNC CLK pin. This enables DC measure-

ment by using a Pin PMU on a digital channel connected

with the SYNC CLK pin. Hence, if you wire a digital

channel with the SYNC CLK pin on the DUT board, you

can perform DC measurement at the DUT pin connected to

the AWG by using a Pin PMU. The following figure shows

the possible routes between the pogo pins and SYNC CLK

pin, which are represented with bold lines. When the DC

route is made, the output amplifier is disconnected from

any pogo pins.

Loop Back Routes

The output multiplexer can make the loop back route

between A+ and B+, between A- and B-, between C+ and

D+, and between C- and D-. When a loop back route is

made, it is disconnected from other routes. Hence, you can

make multiple loop back routes, or also make a loop back

route and another route (output route or DC route) using

other pins at the same time. In the following figure, the

possible loop back routes are represented with bold lines.
