The Keysight 34934A module for the 34980A Multifunction Switch/Measure Unit offers the highest density matrix for connecting paths between your device under test and your test equipment, allowing for multiple instrument connections to multiple points on your device under test at the same time.
The matrix modules can be expanded with the row expansion kit allowing for up to 4096 cross points in a single mainframe. And with the unique row disconnect feature, you don´t have to worry about the added capacitance when connecting multiple matrix modules.
This matrix is easily configured in 1- or 2-wire configurations. The optional configuration block and high density screw terminal block provide ample space for wiring and ensure robust connections to your device under test. The standard 78-pin Dsub connectors also allow for easy connection using standard Dsub cables or mass interconnect solutions.
