2. The frequency reference adopts temperature-compensated voltage-controlled crystal oscillator (2.5 ppm VC-TCXO).
3. Unique gate control method and precise time algorithm (non-timed interrupt method) are adopted.
4. Gate (display refresh) time 0.01 sec/0.1 sec/1.0 sec selectable, real-time display frequency value.
5. Single-ended input design, frequency measurement of three channels (low channel / high channel / automatic channel) optional.
6. Double IF design, IF value and plus/minus mode can be preset individually.
7. Eight 0.56-inch high-brightness digital tube display, eight levels of adjustable brightness.
8. Invalid zero automatic blanking, invalid frequency value display filtering optional, the last blanking optional.
9. Simple circuit, reasonable structure, dual-key control, simple operation.

2.Measurement channels (high and low channels are high resistance)
*Low channel
Measurement range: 0.1 MHz ~ 60 MHz
Measurement accuracy:
± 100Hz (at 0.01 sec gate)
±10Hz (at 0.1 sec. gate)
±1Hz ( 1.0 sec. gate)
Low channel sensitivity:
0.1 MHz ~ 10 MHz: better than 60 mVPP
10 MHz ~ 60 MHz: better than 60mVPP
60 MHz ~ 75 MHz: Not tested
*High Channel (64 divisions)
Measurement range: 20 MHz ~ 1.2 GHz
Measurement Accuracy: ±6400Hz (at 0.01 sec gate)
±640Hz ( at 0.1 sec gate)
±64Hz ( 1.0 sec gate time)
High channel sensitivity:
20 MHz ~ 30 MHz: better than 100mVPP
30 MHz ~ 60 MHz: better than 50mVPP
60 MHz ~ 2.4GHz: not tested
*Auto channel: automatically select high channel or low channel according to the input signal frequency, the recognized frequency is 60 MHz. if the input signal amplitude greater than 60 MHz is insufficient to automatically select the high channel, the high channel should be manually selected for frequency measurement.
