It's using reciprocal counting technique, high accuracy, wide measuring
range, truly equal precision measurement, fast speed measurement,high sensitivity.
single-chip microprocessor technology cycle frequency measurement and
intelligent management, making the instrument has high reliability and
excellent performance / price ratio.
3 It's using LSI design, the
use of CPLD devices, instrument components greatly reduced, reliability
has been greatly improved, the average time between failures ≥10000h.
The machine looks nice, small size, light weight, easy to use.
Frequency Measurement: A Channel:1Hz ~ 100MHz;
B channel: 100MHz ~ 1.6GHz (optional)
Period Measurement: A Channel: 10ns ~ 1s
PPM measurement: -9999 ~ 9999ppm
Upper and lower limit measurement: according to the parameters set by the user of upper limit FU, lower limit FL parameters to measure the measured frequency whether exceeds the lower
limit and upper limit value. if exceed, it will be alarm.
Binning measurement: according to the center frequency F0 set by the user, automatically binned measurements.
Binning value: Pr1 ~ Pr8 can be set between 1 ~ 999ppm
quantity of Binning: according to center frequency F0 is divided into 16 stalls around the midpoint

The frequency or period measurement error: ± time base error ± trigger error ± LSD 100ns
When: LSD = _× measured frequency (or test period)
Trigger error: When the measured signal to noise is 40dB, the trigger error is ≤0.3%
PPM measurement error: ± time base error ± trigger error ± LSD
When: LSD = (100ns / gate time) ×106ppm
For example: When the gate time = 1s, LSD = 0.1ppm
When the gate time = 0.1s, LSD = 1ppm
counting error: ± 1
