16 Matrix Configuration
The 16
×
16 matrix configuration gives you control over the entire
switch matrix with no subdivisions. All 256 crosspoints are treated as a
contiguous block. This configuration provides an easy way to create a full
256 crosspoint matrix for applications requiring equal rows and columns.
Figure 2-9 is a 1-wire representation of the SCXI-1129 configured as a
16
×
16 matrix. The diagram shows connections for a general test setup that
connects several instruments to one complex DUT. In this way, you can use
the same instrumentation to test many different portions of the DUT. You
can access t
he HVAB at up to four rows at a time
. To connect signals to the
HVAB, connect the chosen rows to COM0–COM3, then connect
COM0–COM3 to AB0–AB3. Refer to Figure 2-10 for the channel names
that NI-SWITCH uses.
