Matrix Switch for use with 75 Ohm Network Analyzers

75 Ohm Matrix Switch

Three new 75 Ohm blocking matrix switch models have been added to the JFW website.  Model 75MS-029 is a solid-state 2X8 blocking matrix that operates 3-1000MHz.  Model 75MS-030 is a solid-state 2X6 blocking matrix that operates 3-1000MHz.  Model 75MS-037 is an electro-mechanical 2X12 blocking matrix that operates DC-1700MHz.  These 75 Ohm matrix switches can be used to fan-out connections from a 2-port 75 Ohm network analyzer to allow for automated multi-port 75 Ohm testing.  Connecting the 2X12 matrix in series with a 2-port network analyzer, creates a twelve port test set.  For all three models, the unused output ports are self-terminating at 75 Ohm impedance to keep the DUT properly impedance matched at all times.  All three models are remotely controlled via serial or TCP/IP connections.  The remote command set consists of simple ASCII formatted commands.  The remote command set for our 3.x.x firmware is available for download.  If you have any technical questions about these 75 Ohm matrix switches, please contact our engineering department for assistance.
