Features
- Frequency reference with temperature compensation type voltage controlled crystal oscillator (2.5 ppm VC-TCXO).
- Adopts gate control mode and the accurate time algorithm is unique.
- Gate (refresh) time is 0.1 seconds, real-time display of frequency.
- The precision of frequency measurement 10Hz/100Hz (Rotated the right one) optional.
- Dual frequency design, intermediate frequency value and plus / minus mode can be preset, and do not influence each other.
- Display driver using the LED chip digital tube display, high brightness, less external interference.
- Adopts six 0.56 inch digital tube display, automatic blanking invalid zero, eight stage adjustable brightness.
- Simple circuit, reasonable structure, double button control, simple operation.
- All settings are automatically saved, boot directly call.
