Base Matrix Configuration 2
Keysight 34934A User’s Guide 51
The supplied 20-pin terminators are identical, but the pin assignments for 4x32
are not (Matrix 1 rows are on J24; Matrix 2 rows are on J25). The terminal
numbers—corresponding to the headers—are shown below. Pay careful attention
to the indexing keys on the connectors, to correctly identify terminal #1.
You must fabricate custom cabling to make row signal connections to the central
16 pins (3-18) of these headers, using the pin assignments below. The supplied
blue terminators accommodate 22 AWG coated wire, fitted to “crimp-to-wire”
contacts with latch tabs (FCI part #76357-301LF or equivalent).
