Tektronix CMC250 1.3ghz Frequency Counter 4 Parts/Repair
The CMC250 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 M input for frequency measurements up to 100 MHz. Channel B is a 50 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.
