Microwave Measurement Devices
Slotted Line: It is used to measure standing wave ratio.
The slot in slotted line is cut at the center, because maximum field will be induced to penetrate probe.
Tunable detector: It helps to detect the low frequency square wave modulated microwave signal.
VSWR meter: It is used to measure VSWR. This meter is not useful for VSWR > 10
Power meter: It is used to measure microwave power.
It has power sensor that converts power into heat energy. Temperature change provides an output current that indicates power.
Wave meter: It is used to measure frequency of microwaves in a system by selective basorption of microwave energy in solids.
Spectrum Analyzer: It gives a display of frequency spectrum of input signal. (Gives a plot of signal amplitude vs time)
Network Analyzer : It measures both amplitude an phase of microwave signal over a wide frequency range.
