Phase Matrix's EIP®-brand of frequency counters brings the highest levels of capability and reliability to microwave and millimeter-wave measurements. With the broadest frequency ranges available, very high sensitivity, and 32-watt continuous input protection, EIP® frequency counters are ideal for applications ranging from basic carrier measurements in communcations systems and automatic VCO measurements to the most sophisticated chirped radar profiling.

Our counters are designed around a unique heterodyne architecture that incorporates a YIG-based preselector. The YIG-preselected input provides excellent performance in amplitude discrimination, frequency selectivity, kickback-noise and burnout protection.
