25B & 28B

The 25B and 28B CW frequency counters are ideal for communications applications. These portable, rugged, all-die-cast-body units combine durability and small size with high-performance features typically found in larger, benchtop instruments. The 25B measures CW, FM, AM as well as complex modulated frequencies from 10 to 20 GHz, and the 28B extends the range up to 26.5 GHz.
