Lascells Complete Microwave Set

3cm Microwave Apparatus - Complete Set-All self-contained; no external apparatus required or complicated setting up. This complete system provides a rugged set of units to enable students to investigate the wave properties of 10GHz (3cm) microwaves. Directional Horn Transmitter- This utilises 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 plugtop unit (supplied). Wide Angle Receiver-This uses a plate antenna which gives high sensitivity over a broad area. 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. Precision Probe Detector-This 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 the same type of plug-top supply as used by the receiver unit (above). An additional power supply unit can be supplied if requested.
