Installing SMA Connectors
When installing SMA connectors on the 34941A module, it is recommend
that you tighten them to 0.8 - 1.1 Nm (7- 10 in- lbs) of torque.
Isolating Connector Banks
You can configure each bank on the RF MUX modules to be either
isolated or chassis- grounded. The modules come with chassis- grounded
metal shoulder washers installed on all connectors in each bank of
relays. If you want to isolate a bank from the other banks and from
chassis- ground, you must remove the five metal washers in that bank
and replace them with the provided plastic shoulder washers.
C A U T I O N
SMA connectors are easily damaged, especially when tightening a
neighboring connector with a wrench. To help prevent damage and
contamination, do not remove a connector's protective cap until
immediately prior to installing a cable on that connector.
To isolate a bank from other banks
and chassis-ground, install the
provided plastic shoulder washers
on the connectors in the bank to
be isolated. When installing the
plastic shoulder washers, use
7 in-lbs of torque.
The 34941A and 34942A are shipped
from the factory chassis-grounded
with metal shoulder washers
installed on all connectors in each
bank of relays.
