crystal vibration test machine for electronic component tester
Main feature
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

Upper and lower limit measurement: according to the parameters set
by the user of upper limit FU, lower limit FLparameters 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 F0set by the user, automatically binned measurements.
Binning value: Pr1 ~ Pr8 can be set between 1 ~ 999ppm
quantity of Binning: according to center frequency F0is 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
Fixed gate: 10ms, 100ms, 1s, 10s four types optional
Adjustable Gate: 50ms ~ 95ms in 10 files, each file interval of
5ms.
