Tektronix CMC251

1 Hz to 100 MHz, Multifunction Counter
The Tektronix CMC251 is one of our Multifunction Counters that has a frequency of 1 Hz to 100 MHz.

The Tektronix CMC251 1.3 GHz Multifunction Counter measures the frequency of sine, square and triangle waves from 1 Hz to 1.3 GHz. The CMC251 also provides period, totalize and pulse width measurements.

The counter has two input channels. Channel A is a standard 1 MΩ input for frequency measurements up to 100 MHz. Channel B is a 50 Ω terminated input for use in high-frequency systems.

This counter is of interest to radio amateurs because of its ability to measure high-frequency systems. The temperature-compensated, crystal-controlled time base is stable to ±1 part per million per year.
