3cm Microwave system

Description

All self-contained; no external apparatus required or setting
up complications. The transmitter has its own internal
modulator with variable frequency. The receiver has its own
internal amplifier, loudspeaker and gain control. The probe
receiver has its own internal amplifier, gain and sensitivity
controls and loudspeaker. This complete system provides
a rugged set of units to enable students to investigate the
wave properties of 10GHz (3cm) microwaves.
The 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).
Transmitter measures 110 x 110 x 150 mm high

The Receiver
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. Receiver measures
60 x 110 x 150 mm high.
