Keysight Technologies 34950A Data Acquisition Terminal Block for 34980A Data Acquisition System

The Keysight 34950A module for the 34980A Multifunction Switch/Measure Unit has 64 bi-directional lines configured as eight 8-bit channels. Each 8-bit channel has programmable polarity and thresholds up to 5V. The memory is useful for simulating and capturing digital patterns up to 10 MHz. It provides configurable handshaking protocols for a wide variety of applications.
In addition, the two counter/totalizer channels can be used to count events, frequency, period, duty cycle, totalizer, and pulse width.
Standard 78-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
