With RF MUX switches, you cannot open switches programmatically. You can only close a channel. When you close one channel, another channel automatically opens. Therefore, only one channel relay in each bank is closed at any time. Keysight 34941A-34942A User’s Guide... - Page 11 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.
