2 Base Matrix Configuration
104 Keysight 34934A User’s Guide
The supplied 20-pin terminators are identical. For 4x128, you can only make row
connections to header J24. 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 header J24, 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).
As no row access is provided for J25, keep the supplied safety interlock terminator
installed in J25.
Note that each row signal (R1 through R4 (H,L) is routed out on two pins on J24.
You can make row signal connections to either row (upper, lower) of the
connector.
