●
Except otherwise stated, the accessories shown above are
not
part of
the delivery and must be ordered separately. Use your own cables,
adapters and splitters, if you like. For most converters, the RF IN and
LO IN frequencies do not exceed 20
GHz and hence 3.5 mm cables are
sufficient. Only RPG
ZC750 and RPG
ZCZC1100 require LO frequen-
cies up to 21 GHz and 23 GHz, respectively.
●
In addition, the standard setup relies on the frequency converter control
software option R&S
ZNA-K8 (available for R&S
ZNA firmware V1.90
and higher). Without this option, configuring the port powers and fre-
quencies is extremely tedious and error-prone, and can be hazardous
w.r.t. excessive RF and LO input power levels at the converters.
Tightening RF cables
Tightening RF cables too strongly, can damage cables and connectors. Loose
tightening can result in inaccurate measurement results.
