Tektronix / CDS VX4286 32-Channel Analog/Digital Input Module

  • Single-Slot, C-Size, VXI Module
  • Digital or Analog Modes
  • Time-Tagging (Analog Mode)
  • High Threshold Resolution and Accuracy
  • Wide Voltage Input Range


The Tektronix / CDS VX4286 32-Channel Analog/Digital Input Module is a single width, C-Size printed circuit board assembly for use in a C-size or larger mainframe conforming to the VXIbus specification. The thirty-two inputs of the VX4286 Module can be configured under program control to function either as thirty-two digital inputs (Digital mode), as thirty-two comparator inputs with time-tagging (Analog mode), or as sixteen channels of each (combination Analog/Digital mode).

In either mode, all input channels have individually programmable threshold voltages and can be programmed to active high or active low logic. Two logic threshold ranges are provided: ±10V with an accuracy of 40mV and resolution of 5mV, or ±50 V with an accuracy of 100mV and resolution of 25mV. Each channel may be programmed to use either range or it may be instructed to autorange, selecting the most sensitive range suitable for a specified threshold voltage. The VX4286 also includes facilities for input signal conditioning modules, such as pullups for open collector outputs, A/C detection, or user-designed input circuitry.

The front panel display shows which channel, if any, is on the "wrong" side of its threshold.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
