PNA test set block diagram
Simplified receiver block diagram
With Option 017, the signal is routed out of
the PNA from the front panel jumpers rather
than the ports. Without Option 017, the signal
is routed from the front panel ports to the
combiner assembly, allowing access to the
PNA’s internal bias-tees.
