Radio measurement terminology and definitions
1 Basic Terminology
1.1 Time Domain timedomainmeasurement
Signal amplitude measurement of change over time. Including the signal waveform measurements and the measured object measured response time characteristics.
1.2 frequency domain measurements frequencydomainmeasurement
Signal amplitude versus frequency measured change. Including the frequency spectrum of the signal and the measured object measured response characteristics.
1.3 Data Domain Measurements data-domainmeasurement
The timing and status of signal data flow measurements. Such as logical analysis.
1.4 modulation-domain measurements modulationdomainmeasurement
Frequency signal, the measurement time interval or phase changes with time.
1.5 frequency characteristics frequencycharacteristic
Relationship between measured object parameters and frequency. Frequency characteristics include amplitude-frequency characteristics and phase-frequency characteristics.
1.6 response responsecharacteristic
Under certain conditions, the relationship between the excitation and the corresponding response.
1.7 Selective selectivity
Characterization of signal interference measurement capability with other signals of a frequency phase difference means required. The receiver
Introduction selectivity is the ability to choose from a number of signals of different frequencies in the signal out of the required characterization of the receiver.
1.8 real-time measurement of real-timemeasurement
Measured in real time process occurs, collect all the required raw test data, followed by (or over a period of storage
Later time) by the measurement data processing are given all the necessary measurements.
1.9 reflection parameters reflectionparameter
Used to describe the parameters of the reflective properties of the network ports.
Described reflection characteristic impedance parameters in addition, there is a voltage standing wave ratio (the VSWR), reflection coefficient (Gamma) and back
Wave loss (LR).
1.10 transmission parameters tran
