Microwave Kit complete with accessories.Kit contents:1 x Microwave Receiver1 x Microwave Transmitter1 x Microwave Probe ReceiverAccessory Kit: 2 x Aluminium Reflectors (210 x 210mm) 1 x Aluminium Reflector (210mm x 60mm) 1 x Hardboard semi-silvered reflector (210mm x 210mm) 1 x Polarisation GrilleThe Microwave Probe Receiver gives a localised precision receiver which finds particular application in identifying areas of peak and low amplitude in interference reflection and refraction experiments. There are two controls one for sensitivity and the other for volume of output to the internal loudspeaker. Power is from a mains plug-top unit. Output can be monitored by a CRO connected to the 4mm sockets for quantitative measurements.The Microwave Receiver uses a plate antenna which gives high sensitivity over a broad area. The output is to an internal loudspeaker and power is derived from a mains plug-top unit (supplied). A control allows the user to adjust the sensitivity to cater for different circumstances and distances.The Microwave Transmitter utilizes a Schottky diode oscillator module feeding a tuned waveguide and horn to give a directional microwave beam. The beam is modulated with a variable frequency audio signal which can be adjusted by the control on the top panel. Power is from a mains plug-top unit (supplied).
