International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / At present, there is no means of instrument direct measurement to frequency deviation
when it is up 500kHz. But the frequency deviation of high bit rate telemetry transmitter is
700kHz or more. In this paper, an indirect measurement method using spectrum analyzer
and counter is put forward. It effectively solves the measurement problem of frequency
deviation and frequency response of high bit rate telemetry transmitters. Measuring theory,
summary of experiences and difficulties in measuring work, have been deeply studied with
the viewpoint of how to avoid the limitation of different methods of measurement. Focused
on the establishment of an automatic measuring system, expert system, skilled data and
software of the system are studied in detail. The data for comparison is also supplied.
Finally, the analysis to the measuring error and general uncertainty is given.
