Frequency calibrator VCH-313 is intended for calibration and verification of different types of frequency standards, using precision signal, transmitted by satellite navigation systems GPS/GLONASS. The device can also perform periodical frequency correction of a calibrated frequency standard in special automatic mode.
Input signals from the external frequency standard: 1 MHz – 20 MHz with the amplitude 0,7 – 3,5 V on 75 Ohms load. Input signal frequency is to be set by the user manually with the step 0,001 MHz.
Frequency calibration error of an input signal (frequency calibrator mode) depends on measurement time.
Minimal frequency calibration error for measurement time more than 10 days, is 1x10-13.
Calibrator forms the signal for an external standard frequency correction in digital or analog form. Adjustment slope is to be determined by user.
Power: AC 220V; 50 – 60 Hz, or DC 48 ± 10V (depends on order).
Power consumption <15W.
Start up time <15 min.
Dimensions (without antenna and a cable): 340x235x140mm.
Weight: <3,5 kg.
