Optoelectronics 3000A Plus 10Hz-3GHz Frequency Counter

  • Digitally Filters RF Signal Measurements
  • Internal Memory for Up to (3) Filtered Frequencies
  • (4) Separate Input Amplifiers


The Optoelectronics 3000A Plus 10Hz-3GHz Frequency Counter combines computing power of a microprocessor with the OE10 high speed counter IC to provide unparalleled counting capabilities. The 3000A Plus can capture off-the-air signal frequencies completely without operator intervention - and record the result in internal memory.

The microprocessor digitally filters the RF signal measurements and reduces spurious counting. All of this is done without relying on the signal strength to exceed some arbitrary level, ensuring reliable performance in today's dense signal environments. Proprietary software monitors the incoming RF for stable coherent signals, and only when these conditions are satisfied will the count be presented to the user. Internal memory allows the 3000A Plus to store the last three filtered frequencies for later examination. At any time later, the 3000A Plus memories can be recalled to check the results of an extended monitoring period.

The 3000A Plus has four separate input amplifiers to push sensitivity to new levels. This was done for a very simple reason: the wider the bandwidth of a counters front end, the higher its inherent noise floor and the lower the sensitivity.

This does not mean the 3000A Plus sacrifices bandwidth for sensitivity. However, the input circuitry has been designed to cover the 10Hz - 3GHz range in bands, chosen to optimize sensitivity for each application.

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!
