It is classical continuous wave spectrometer [34] using klystron source operating at X band and with standard sensitivity around [10.sup.10] paramagnetic particles in the interaction volume of [TE.sub.011] resonator.
The second stage consisted of a frequency multiplying klystron (a linear beam vacuum tube), wherein frequency was modulated by a 13.8 MHz oscillator that multiplied the signal to about 2.983 GHz.
Aerodist master units essentially comprised: a klystron oscillator that set the carrier signal frequency that allowed voice communication with remote units, and later broadcast the measuring pattern frequency signals; a triode power amplifier that amplified carrier and measuring signals for transmission through the aircraft antenna system; and ovens for the crystals that determined the pattern frequencies that were automatically switched over the carrier frequency to give the measuring signals for relevant distant components.
