Using temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO).
Unique gate control and precise time algorithm (non-timed interrupt).
Gate (display refresh) time 0.01 seconds / 0.1 seconds / 1.0 seconds, real-time display frequency value.
Single-ended input design, three-channel frequency measurement (low channel / high channel / Auto Channel).
Dual frequency design, value and IF / down mode can be preset separately.
Using eight 0.56 inches high brightness digital display, eight adjustable brightness.
Circuit is simple and reasonable structure, two-button control, simple operation.
The settings are automatically saved, boot directly call.
1:Gate time
2:Measurement channels (Both high and low channels are low impedance)
low channel
Measuring range: 0.1 MHz ~ 60 MHz
± 100Hz (0.01s gate time)
 ± 10Hz (0.1s gate time)
 ± 1Hz (1.0s gate time)
Low channel sensitivity:
0.1 MHz ~ 10 MHz: better than 60mVPP
10 MHz ~ 60 MHz: better than 60mVPP
60 MHz ~ 75 MHz: No tested
high channel (64 divider):
Measuring range: 20 MHz ~ 2.4 GHz
± 6400Hz (0.01s gate time)
 ± 640Hz (0.1 1s gate time)
± 64Hz (1.0 1s 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
Automatic Channel:
Automatically selected according to the input signal frequency high or
low channel channel, identifying the frequency of 60 MHz. Such as
when the input signal amplitude is greater than 60 MHz shortage
can not automatically select high channel,
the channel should manually select high frequency measurement.
3.IF settings
Independent double-IF design, adjust the minimum frequency step of 100 Hz,
frequency range 0 ~ 99.9999 MHz,
can be set to increase or decrease the IF frequency mode.
4. Frequency reference
Using 5032 package 13.000MHz Warming voltage controlled crystal oscillator (VC-TCXO),
frequency stability of ± 2.5 ppm.
5. Operating voltage
DC Input: DC 9V ~ 15V (with reverse polarity protection)
6 Current Maximum 160 mA (test conditions:  
DC12V power supply;  red LED;  eight brightness)
7.Eight LED display, the highest display eight digits.
8.Eight LED brightness is adjustable,
factory set to maximum brightness.
