8 x 8 Blocking Matrix Switch Covering DC-18GHz

/in , /by

JFW model 50MS-404 is an 8 x 8 blocking matrix switch operating DC-18 GHz.  It is constructed using electro-mechanical switches on the input half and output half of the matrix.  This type of construction results in low insertion loss and high port-to-port isolation.  All unused input ports and unused output ports are absorptive (i.e. self-terminating into 50 Ohm terminations).  The matrix can be set manually using the keypad or remotely via an Ethernet or Serial connection.

  • Configuration:  8 x 8 blocking matrix
  • Frequency Range:  DC-18 GHz
  • Input Power:  1 Watt (hot switch), 30 Watts (cold switch)
  • RF Connectors:  N female or SMA female
  • Remote Control:  Ethernet or Serial
  • 19 inch rack mount enclosure

Here are some brief examples of our remote commands for controlling the matrix.  We provide a firmware manual with all test systems that show command syntax and examples. <CR> denotes a carriage return.  <LF> denotes a line feed.

Syntax for Setting Paths:
SI x1 y1, x2 y2, …, x8 y8<CR>       Set input port command
SO x1 y1, x2 y2, …, x8 y8<CR>     Set output port command

Syntax for Reading Path Settings:
RI x1, x2, …, x8<CR>       Read input port setting.
RO x1, x2, …, x8<CR>     Read output port setting.

Remote Command Examples:
SI 2 1<CR>             Set input port 2 to output port 1
RI 2<CR>               Read input 2
Input 2 <-> Output 1<CR><LF>    Response
SI 1 5, 2 6<CR>     Set input 1 to output 5, and input 2 to output 6
SO 4 1<CR>           Set output port 4 to input port 1
RO 4<CR>             Read output 4
Output 4 <-> Input 1<CR><LF>    Response
