Description:
Plug-In Spectrum Analyzer
Information
These Analyzers are designed Co provide coverage of three
frequency ranges; 10 cps to 20 kc, 35 cps to 100 fcc, and
150 cps to 500kc. models 011, 012 and 013 are provided with
calibrated Center Frequency and Dispersion dials, while
models 001, 002 and 003 are uncalibrated.
These units are designed so that they may be conveniently
plugged into any Oscilloscope which accepts the Tektronix
letter series plug»ins. By simply installing one of these
Plug-In units, the Oscilloscope becomes a complete Spectrum
Analyzer. In use, the sawtooth output of the Oscilloscope is
utilized to provide a signal for sweeping the Spectrum
Analyzer Oscillator. Ail voltages for Spectrum Analyzer
operation are obtained automatically when the Analyzer is
plugged into the Oscilloscope.
