451 EIP Microwave Frequency Counter

The 451 is a Frequency Counter from EIP Microwave. When an engineer needs a piece of electronic test equipment that will accurately measure frequency, he or she uses a frequency counter. Frequency counters measure a repetitive electronic signal’s oscillations per second. This tool uses a frequency counter, which analyzes the number of oscillations or pulses in a specific time. There are frequency counters designed for radio and microwave frequencies, depending on the application.
