  • Page 12: General Description

    You may connect E1475A Expander or E1473A Expander to the E1472A or E1474A Multiplexer. The drivers on both modules can support either of the expander relay modules.

  • Page 13: Typical Configuration

    Typical The RF Multiplexer and Expander relays are configured in a “tree” structure which provides high isolation and low VSWR (voltage standing wave ratio). Configuration Each channel can switch user inputs up to 24 Watts (42V peak). User input frequencies to the 50 Ohm RF Multiplexer and Expander modules can be from DC to 3 GHz.

  • Page 14: Programming The Rf Multiplexers

    Programming the RF Multiplexers To program the RF Multiplexers using SCPI, you must select the controller language, interface address, and SCPI commands to be used. Guidelines to select SCPI commands for the RF Multiplexers follow. See the specific command module manual for interface addressing and controller language information.

  • Page 16 Channel Numbers The channel numbers are 00-03, 10-13, 20-23, 30-33, 40-43, and 50-53. The channel is addressed using channel numbers. Use commas (,) to form a channel list. Only valid channels can be accessed in a channel list. NOTE The RF Multiplexer will accept and execute channel ranges (ccmmnn:ccmmnn) without generating an error, but the result is to close the last channel in each bank within the range specified.

  • Page 17: Initial Operation

    Initial Operation You can use the following program example to verify initial RF Multiplexer operation by closing a channel and querying channel closure. The example first resets the switchbox and then closes channel 02 of a single RF Multiplexer module (card number 1) in the switchbox. The program next queries the channel closure state.

    Setting the Address Switch The logical address switch (LADDR) factory setting is 120. You may have changed the setting during module installation. Valid address values are from 0 to 255. If the RF Multiplexer is used with a command module in a C-Size mainframe, see the command module user’s guide for addressing information.

  • Page 20: Selecting The Interrupt Priority

    Selecting the Interrupt Priority The RF Multiplexer module generates an interrupt after a channel has been closed. These interrupts are sent to, and acknowledgements are received from, the command module via the VXIbus backplane interrupt lines. For most applications where the RF Multiplexer module is installed in a C-Size mainframe, the interrupt priority jumper does not have to be moved.
