If you're working with precision test equipment like the HP or Agilent 53131A, 53132A, or 53181A frequency counters, you know that accuracy is everything.

This is a high stability OCXO (Oven Controlled Crystal Oscillator) replacement module for those exact units.
Over time, the internal timebase can drift, affecting your measurements.

Swapping in this new OCXO can restore or even improve the accuracy of your counter.

It's a brand new, generic/unbranded part that's designed to be a direct replacement.

It comes in simple anti-static packaging, ready to be installed.

If you rely on your Agilent gear for critical work and need that rock-solid frequency reference, this is the component you need to keep your measurements spot-on.

Don't let an old oscillator compromise your lab work.
