2 Base Matrix Configuration
140 Keysight 34934A User’s Guide
Typically, you could make both row and column connections to each module by
fabricating custom cabling terminating in female D-Sub connectors. These attach
to the configuration block’s male D-Sub connectors P1 and P2. For 8x32, all rows
connect to P2.
Alternately, you may choose to connect only columns (typically test points on
your DUT) to the D-Subs. There may be physical or electrical advantages in
making your row connections (typically measurement devices) to the
configuration block’s blue extension connectors J3, J4, J5 and J6. To provide this
flexibility, two extension headers are provided on each side of the configuration
block.
You must have set the jumpers (in “Placing Row Extension Jumpers on the
34934C-002 Configuration Block” on page 136) to extend rows to two of the four
headers. We’ll call these the “live” headers.
