- Brief description: This frequency counter is based on CPU with 8 digits LED display. The range is from 10Hz~2.5GHz. It has frequency counter, pulse counter and crystal test functions.
- Specifications: Frequency measurement has been divided into 3 range: 10Hz~4M. 4M~50M (Input A, input impedance: 1M Ω ), 50M~2.5G(Input B, input impedance: 50 Ω ). Gate time is divided to 4 ranges: 0.1S, 1S, 5s, and 10s.
- Resolution:
- 5Hz ～ 4M: 0.1Hz ～ 10Hz ；
- 4M ～ 80M: 1Hz ～ 100Hz ；
- 50M ～ 2.5G: 100Hz ～ 1KHz.
- Accuracy : base time X frequency ± 1 digit.
- Crystal test: 3.5M ～ 16M
- Input sensitivity:
