Phase Matrix 548B

The 545B and 548B frequency counters are popular in R&D labs and production test settings because they perform multiple duties and a variety of applications. They provide the capability to selectively measure individual signals in a multi-signal environment. Additionally, they can simultaneously measure the average power level of the isolated input signal.

The 545B measures CW, FM, and AM frequencies from 10 Hz to 20 GHz, and the 548B extends the range to 26.5 GHz. Optionally, the 548B's range can be further extended to 110 GHz.

All Phase Matrix EIP® brand frequency counters are based on a unique heterodyne architecture that incorporates a YIG-based preselector. The YIG-preselected input provides unparalleled performance, in amplitude discrimination, frequency selectivity, kickback noise, and burnout protection.
