3.7 GHz Frequency Counter

Description
3.7 GHz frequency counters usually measure the number of oscillations or pulses per second in a repetitive electronic signal. It is mainly made up of time-base circuit, input circuit, counter display circuit and control circuit. This device can be used for developing, testing and repairing electronic equipment.

Notes
1. 3.7 GHz frequency counter should be equipped with suitable line voltage.
2. To avoid electrical shock, the protective grounding conductor of power cord should be connected to ground.

Maintenance
1. To maintain good ventilation, regular cleaning should be carried out.
2. Do not spray cleaner directly onto the instrument when cleaning it and use a soft cloth with mild detergent and water instead.
