Instrument calibration is one of the primary processes used to maintain instrument accuracy. Calibration is a comparison between measurements one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.
The device with the known or assigned correctness is called the standard.
The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.
The formal definition of calibration by the International Bureau of Weights and Measures is the following: “Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication.
RF Power Calibration Improves Performance of Wireless Transmitters.
Measurement and control of RF power is a critical consideration when designing a wireless transmitter.
High-power RF amplifiers (HPAs) rarely operate in open-loop mode, that is, where the power to the antenna is not in some way regulated.
