Product name：Crystal Vibration Tester 1HZ~100MHZ

1 It's using reciprocal counting technique, high accuracy, wide measuring range, truly equal precision measurement, fast speed measurement,high sensitivity.
2 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.

Measuring range
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 F_U, lower limit F_L 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

Measurement error
The frequency or period measurement error: ± time base error ± trigger error ± LSD 100ns
When: LSD = _× measured frequency (or test period)

Gate time

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

gate time
