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.

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.

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.

The 34941A and 34942A are shipped from the factory chassis-grounded with metal shoulder washers installed on all connectors in each bank of relays.

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.
