DC Routes
The input multiplexer can make the route between a pogo
pin and the SYNC CLK pin. This enables DC measurement
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 a
digitizer 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 input amplifier is disconnected from
any pogo pins.
