Tektronix CMC251
Frequency Counter 1Hz to 1.3GHz
Description
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 has 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. The temperature-compensated, crystal-controlled time base is stable to ±1 part per million per year.
