Calibrator is a special reference measure designed for verification , calibration or calibration of measuring instruments , installations by comparison. Typically, calibrators refer to reference sources of electrical radio signals, although there are calibrators that reproduce other physical processes or phenomena with specific, precisely defined parameters.
Content
Some types of calibrators
- Microwave power calibrators - for checking wattmeters , microwave power meters , EMC power converters
- Voltage and current calibrators - for checking voltmeters , ammeters , electrical signal converters
- Calibrators of electrical resistance , capacitance , inductance - for checking ohmmeters , immitance meters
- Frequency calibrators - sources of electrical signal of precision frequency
- Oscilloscope calibrators are pulse generators , precision in amplitude and frequency. Such a device is usually built into the oscilloscope and is designed to calibrate it by horizontal and vertical deviation before starting work
- Calibrators of radio altimeters , radio rangefinders - delay lines that simulate the delay of a radio signal when it passes a certain distance in space
- Temperature and pressure calibrators - for checking thermometers , manometers , barometers
- Acoustic calibrators - precision sound sources for checking and calibrating sound level meters
