It is a high-resolution multifunction intelligent frequency counter based on microprocessor. Features include frequency, period and equal-precision measuring. Also, 3 step function selection, work state, unit and eight-digit LED display. All function depend on a single CPU. A crystal controlled temperature circuit provides constant compensation for temperature change thereby reducing measurement errors typically caused by temperature drift. The CH.B input has an attenuator(X1,X20), &AC/DC coupling for The instrument measures signals over a wide range from 0.01Hz to 2.4GHz. The gate time is continuously The instrument provides high performance stability, & function at a low cost. Note: Read this chapter carefully before using your instrument retain these instructions. 1) 8-digit LED display, clear reading 2) Selective range, high stability 3) Frequency measurement: 0.01Hz ~2.4GHz 4) Cyclic measurement range: 0.5nS~10S 5) Gate adjustment range: 100mS~10S continuous adjustable   frequency range : DC couple 0.01Hz to 100Hz                      AC couple 100Hz to 50MHz   Sensitivity     :"AC" 100Hz-50MHz<=80m Vrms                     "DC" 0.01Hz-1Hz<=500m Vp-p                     1Hz-100Hz<=80m Vrms.   Max.safety voltage: 30V (DC/AC peak)   Frequency range  : from 50MHz to 2.4GHz   Sensitivity      : 50MHz-1.2GHz<=80m Vrms   1.2GHz-2.4GHz>80m Vrms   Coupling         : AC only 3) Resolution       : Resolution depends on gate time control setting.    Step        Coupling        Freq.Range                          Resolution                                                              Gate time min.         Gate time max.     1            AC            1GHz-2.4GHz                   1kHz                 100Hz     1            AC            50MHz-1GHz(excluding 1GHz)    1KHz                  10Hz     2            AC             2MHz-50MHz                   1KHz                  10Hz     3            AC            100Hz-2MHz                    10Hz                  0.1Hz     3            DC            0.01Hz-100Hz(excluding 100Hz)            0.001Hz   short time stability        : +/-3*10 ^-9/second   Long time stability        : +/-2*10 ^-3/month   Temperature drift coefficient: +/-1*10 ^-7,10C-40C   Line voltage variation      : +/-1*10 ^-7 for line voltage +/- 10% 5) Gate time                   : Continuously variable,from 100ms to 10s. 6) Display                     : 8digit, 19*12.5mm LED with steps, frequency, period, kHz/s and MHz/ms, indicator. 7) Precision                   : standard time error(t)* frequency(f) +/-1d 8) Power supply                : 220V/110V +/-10%, (50Hz/60Hz) +/-5% 9) Preheat time                : 20 mins 10) Operation environment      : 0C-50C, 10-90% R.H. 11) Weight                     : Approx. 1.6kg All our SP serial Frequency Counters are provided one year warrantee by us from the date you make a purchase.
