Product Overview

The 34950A is a 64-bit digital I/O Module with memory and counter. This module can be used to simulate or detect digital patterns. It has eight 8-bit digital I/O channels with handshaking, pattern memory, two 10MHz counters with gate functions and a programmable clock output. The digital I/O bits are organized into two banks of 32-bits. The I/O bits can be configured and programmed as inputs or outputs in 8-bit channels. The digital outputs can be configured as active drive or open drain outputs with a 10kΩ pull up. User supplied pull up resistors for up to 5V outputs are also acceptable. The digital inputs have programmable thresholds up to 5V for compatibility with most digital logic standards. The on-board pattern memory can be used to select and output digital stimulus or bit-stream patterns or to capture external digital data. Each bank has independent memory and directional control so that one bank can output data while the other captures data.
  • Configurable handshaking protocols including synchronous and strobe
  • Programmable polarity
  • Internal alarming for maskable pattern match
  • Connections via standard 78-pin D-sub cables or detachable terminal block
  • 1 Hardware pattern interrupt per bank
  • Variable active high drive output from 1.65 to 5V or open drain
  • Variable input thresholds from 0 to 5V
  • Source or sink up to 24mA with an Imax of 400mA per module
  • 1038-channel/second Measurement into memory
