Buying Guide

How to Choose a Frequency Counter

Match the instrument to your measurement requirements.

Frequency Range

General-purpose bench counters cover DC to 225–350 MHz. RF and microwave applications require counters rated to 3 GHz or higher. Always select a counter with at least 20% headroom above your highest signal frequency.

Resolution & Speed

Resolution (digits per second) determines how precisely the counter distinguishes close frequencies. The Keysight 53132A delivers 12 digits/s — sufficient for most calibration and production testing.

Refurbished vs. New

All Micro Precision Test Equipment refurbished units pass ISO/IEC 17025 calibration verification. Refurbished Keysight counters deliver OEM performance at 60–80% below list price, backed by our 30-day return policy.

FAQ

Frequently Asked Questions

Are your refurbished frequency counters calibrated?

Yes. Every refurbished unit sold by Micro Precision undergoes full ISO/IEC 17025 accredited calibration. Each instrument ships with a calibration certificate traceable to NIST standards.

What is the difference between a universal counter and a frequency standard?

A universal counter (e.g. Keysight 53132A) measures external signal frequencies. A primary frequency standard (e.g. Keysight 5071A) generates an ultra-stable reference frequency used to calibrate other instruments.

Can I request a quote for high-value instruments like the Keysight 5071A?

Yes. For instruments priced above $5,000 we recommend requesting a quote for volume discounts, financing options, or bundled calibration packages. Use the Request a Quote button on the product page.
