Please read this instruction sheet carefully before putting the unit into operation!

Prescribed use

The Gunn oscillator is used to generate microwave power for experiment purposes in voca-

tional training and education.

• Avoid looking directly into the end of the radiating waveguide.

• Any eventual disassembly of the oscillator during experimentation into its 4 main com-

ponents is performed using the quick connectors and the thumb screws. Any further di-

sassembly of the componets may not be carried out.

• During operation make sure that all of the components of the Gunn oscillator are securely

fastened, i.e. tighten the thumb screws securely.

• The DC power supply of the Gunn oscillator may only be supplied using the LD power

supply equipment. This rules out any accidental interchanging of the polarity. Any excess

voltage – even in the form of a "brief voltage surge" – leads to irreparable damage to the

Gunn diode.
