The device may be the main error of frequency on a scale of 1%. Additional error when the temperature is 10 º C - 0.7%.
Generator G4-42 subject to the following changes of frequency:
- When adjusting the signal level - 0,03 F;
- After warming up during the 1:00 - 0,0002 F +20 Hz;
- Parasitic frequency deviation in either CW - 0,003 F.
The limits of the output voltage calibrated, which allows the generator G4-42 is in the range of 0.1 mV - 110mV. The highest level of uncalibrated voltage is 1V.
Generators G4-42 allow the following error:
- Set the reference voltage - 4%;
- Setting attenuator - 11%.
The instability of the reference voltage after the warm-up was 2.5%. Harmonic Distortion generator output is 5%.
Parasitic amplitude modulation either CW - 1%. The frequency of the internal amplitude modulation of 0.4 kHz, 1 kHz. Limits set the modulation depth - 10% - 95%. The basic error of the depth of modulation generator G4-42 is 5%. The basic error of the depth of modulation for external modulation - no more than 10%.
Voltage of the modulating signal G4-42 - up to 80V. External modulation frequency range - in the range of 0.05 kHz - 10 kHz. Change limit external modulation depth - 10% - 95%. Total harmonic distortion of the output signal generator G4-42 is 5%.
Generator G4-42 is ready for operation after 30 minutes. Operating temperature of the device is in the range from -10 º C to 40 º C. Relative humidity - 90%.
