34950A 64-bit Digital I/O with Memory and Counter for 34980A
The 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, totalize, and pulse width. Standard 78-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
