4 x 4 Non-blocking matrix example
Using a Model 2750 and four Model 7711/7712 cards, a 4
×
4 non-blocking matrix can be created. Figure 5 shows how to
connect the 7711/7712 modules. This configuration provides a convenient way to simultaneously connect up to 4 DUTs to 4
different test instruments. Use a short coaxial cable to connect the OUTs of each module as shown. contains a couple of
sample commands to control the matrix.
To use , select the IN connection (IN 1 – IN 4), and then in the same square select the OUT connection (OUT1 - OUT4). Send
the
ROUTe:MULTiple:CLOSe
command with the channels in both “Ch” columns.

ROUTe:MULTiple:CLOSe (@101,405) Routes signal from IN1(OUT A of slot 1) through
OUT4 (OUT B of slot 4).
ROUTe:MULTiple:CLOSe (@101,405,108,302) Routes signal from IN1 (OUT A of slot 1) through
OUT4 (OUT B of slot 4), and also from IN2 (OUT B
of slot 1) through OUT1 (OUT A of slot 4).
