2 Base Matrix Configuration
166 Keysight 34934A User’s Guide
These “row connections” are the traditional access points from field wiring to the
matrix rows. In practice, your arrangement of test instrumentation and DUT test
points will determine if you wish to make row connections at the D-subs, at the
blue 20-pin extension connectors, or both.
Setting these jumpers provides you the flexibility to plan how to route your custom
cabling.
The following illustration shows the jumper block J8, along with the relevant
guidance provided on the board’s silk-screen for jumper placement.
If you plan to connect row signals to D-sub connector P2, place two 2x8
jumpers on block J8, as shown below.
If you do not need to connect row signals to D-sub connector P2, place two 2x8
jumpers on block J8, as shown below.
Note that by not routing signals to the D-sub connectors, module bandwidth may
be preserved and capacitive loading minimized.
Placing Row Setting Jumpers on the 34934C-002 Configuration Block
The jumpers in 3x16 jumper blocks J 15 and J16 (left and right of lower board
center) set the row depth (i.e. 8-rows or 16-rows) for the expanded matrix. In
conjunction with the CONFIG jumpers, these jumpers set the matrix configuration.
