16x32 Matrices
16x32 Topology 
You can select the 16x32 matrix configuration by setting jumpers on the 
appropriate terminal block or configuration block, or by D-Sub wiring. 
Once configured for 16x32, the 34934A creates a single matrix, with 512 
crosspoint non-latching reed relays organized in a 16-row by 32-column 
configuration. On the 34934T-002 terminal block, the columns are numbered 
1-32; the rows R1-R16. In the pin assignment diagrams and tables, the 
numbering is C1-C32 and R1-R16.
The matrix is created by jumpering the columns
 on all four of the 4x32 relay banks 
together. This is done automatically through the “CONFIG” jumpers on the 
terminal and configuration blocks, or by shorting pins between your D-Sub 
cables. The column jumpers are not indicated in the example.
On the 34934T-002 terminal block, there are redundant sets of terminals provided 
for columns 1-32, one set on each side of the block. Unlike the 8x32 and 8x64 
modes, the like-labeled terminals on both sides of the block are not shorted to 
each other by traces in the block; you must supply a wire jumper for each column. 
Details on providing these jumpers are on page 185. After these jumpers are 
placed, you may connect any column to the appropriate open terminal.
16x32 Test Circuit Example
The example below shows two circuit paths through the matrix. The upper path 
shows the DUT and test instrument both connected to columns through row R10; 
the other path shows the test instrument connected through a Row Protection 
Resistor on row R14. That circuit path may include series resistance, depending 
on the programmed mode for row protection (see “Row Protection” on page 15).
