Standard arrangement with 4 external test sets
With four external test sets, using 2 times the left diplexer variant (Var 12) on the
left side would be impractical. If their 1
mm connectors must be placed close to
each other, e.g. for on-wafer probing, the RF cables connected to the
of the outer test set would have to be bent unduly to bypass the inner test
set. Same problem with 2 times Var 18 (right) on the right side.
For this reason, the R&S
ZNA67EXT with four external test sets uses a Var 18
diplexer for the outer left test set, and a Var 12 diplexer for the outer right set.
Figure 6-7: Standard arrangement for 4 external test sets
For both outer test sets, a cable deflector is mounted on the connector panel.
Semi-rigid cables redirect the corresponding RF connectors towards the VNA.
6.3.1
Test port
1
mm (m) connector on the front side of the diplexer, serves as an
output for RF stimulus signals and as an input for the measured
RF signals from the DUT (response signals).
