34932A Dual 4x16 Armature Matrix
The 34932A dual 4x16 armature matrix contains two matrices, each with 64
2-wire crosspoint latching armature relays organized in a 4-row by 16-column
configuration. Every row and column are made up of two wires each, a high (H)
and a low (L). Each crosspoint relay has a unique channel number representing
the row and column that intersect to create the crosspoint. For example, channel
315 represents the crosspoint connection between row 3 and column 15 (all
columns consisting of two digits; in this case the digits are 15). See the simplified
schematic on
You can connect any combination of inputs and outputs at the same time.
However, only Matrix 2 in this module connects to the Analog Buses. By closing
channels 921 and 922 you can connect rows 5 and 6 respectively to the internal
DMM of the 34980A mainframe for voltage and resistance measurements. You
can connect multiple matrix modules externally and/or through the Analog Buses
for applications that require large matrices. For information on linking multiple
matrix modules, refer to
of this manual.
When the power is off, matrix relays maintain state, and Analog Bus relays open.
NOTE
When the DMM is scanning, it controls ABus1 and ABus2 relays, which are on
Matrix 2. Therefore, consider this behavior when you are connecting matrices.
