DESIGN AND CALIBRATION OF AN AIRBORNE MULTICHANNEL SWEPT-TUNED SPECTRUM ANALYZERHamory, Philip J., Diamond, John K., Bertelrud, Arild 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the design and calibration of a four-channel, airborne, swept-tuned
spectrum analyzer used in two hypersonic flight experiments for characterizing dynamic
data up to 25 kHz. Built mainly from commercially available analog function modules, the
analyzer proved useful for an application with limited telemetry bandwidth, physical
weight and volume, and electrical power. The authors discuss considerations that affect the
frequency and amplitude calibrations, limitations of the design, and example flight data.
