2 Base Matrix Configuration
56 Keysight 34934A User’s Guide
For a base configuration of 4x32,
place sixteen horizontally
positioned jumpers as shown at
right.
This board configuration “extends” the four row signals either left to connectors J5
and J6 or right to connectors J3 and J4, depending on the placement of jumpers
in block J7. The row signals will also be extended to male D-Sub connectors P1
and P2, if “enabled” by placement of jumpers in block J8.
Placing Row Extension Jumpers on the 34934C-001 Configuration Block
The jumpers in 16x3 jumper block J7 (at board center) determine if row
connections can be made from the left or right side of the board (i.e. they “extend”
the row signal connection points out to only one of the two pairs of blue 20-pin
connectors at the sides of the configuration block).
Note that “row connections” at minimum include the connections between
modules in the matrix, but may also include your access from field wiring to the
matrix rows.
Setting these jumpers provides you the flexibility to plan how to route your custom
cabling, depending on slot placement of the individual 34934A modules and their
corresponding 34934C-001 blocks.
The following illustration shows the jumper block J7, along with the relevant
guidance provided on the board’s silk-screen for jumper placement:
NOTE
The arc shown on the silk-screen—joining the two pairs of CONFIG JUMPER
blocks—is a reminder that you must set all four blocks J10, J11, J12 and J13
identically.
