Use RF connector adapters as port savers
SMA and K-type RF connectors have a limited lifetime. It is typically limited
to 500 connector mating cycles, due to normal wear. After this number of
mating cycles, the connectors must be replaced.
●
The
SMA connectors on the 8 DUT ports
at the front panel of the
R&S
OSP-B157W8 and R&S
OSP-B157W8PLUS
are soldered in
.
Therefore, their replacement is a costly and time-consuming procedure,
which must be handled by Rohde
&
Schwarz
.
To save the lifetime of these RF connectors, use the 2.92
mm K-type RF
connector adapters as port savers on the original connectors. A set of 8
adapters is included in the delivery. Fix the adapters with a torque of
0.8
Nm to 1.1
Nm.
Leave the port saver adapters on the ports and connect your DUT chan-
nels to these adapters, until the lifetime of the adapters is reached, due
to wear. Then replace the worn port saver adapters for new ones.

●
If any SMA or K-type connectors of the R&S
OSP-B157WX are worn,
replacing these connectors is much more simple, because they are not
soldered in.
