Power and Attenuation Measurements and Instruments

There are a variety of instruments available which measure power. The instrument which gives the most accurate measurement is the power meter and a power sensor. The power sensor is an “RF power to voltage transducer”. The power meter displays the detected voltage. This value of power may be in log (dBm) or linear (watts) […]

Difference Between Active And Passive Instruments

Difference Between Active Instruments and Passive Instruments

Instruments are segregated into two categories; one is Active Instruments and second is Passive Instruments. This segregation is according to whether the instrument output is completely produced by the quantity being measured or the quantity being measured simply modulates the magnitude of the some external power source. Passive Instruments Example of the passive instrument is […]
