  • Notes
  • Low Frequency Spectrum Analyser Plug-In for the 5000 series chassis scopes. Covers frequencies 100 Hz to 100 kHz plus a Log span from 20 Hz to 25 kHz. Used mainly for audio testing. The 5L4N is a 0- to 100-kHz spectrum analyzer that offers both high performance and economy. The analyzer features selectable input impedances, 80 dB of dynamic range, and a built-in tracking generator. This analyzer is especially suited for noise and distortion studies in the audio range and comes equipped for 20 Hz to 20 kHz log sweeps.
    Many educators prefer this economical analyzer to teach frequency related theory and demonstrate practical application in the areas of speech, sound, music, vibration, audio, broadcasting, and many others.
    The 5L4N can be used with any 5000-Series Oscilloscope Mainframe. Only two compartments are occupied by the analyzer so that, with the addition of a vertical plug-in, basic oscilloscope functions may be obtained. We recommend the use of a 5111 Storage Oscilloscope for maximum utilization of the analyzer.
    FREQUENCY CHARACTERISTICS Range — 0 to 100 kHz
    Accuracy ~-3 kHz (fine tune control midrange and span/div calibrated for 10 kHz)
    Resolution Bandwidth — The resolution bandwidth is continuously variable from 3 kHz to 10 Hz
    An AUTO mode provides the best resolution for the frequency scan and sweep rate selected. Signal level change over the resolution bandwidth range is 2 dB or less. Line frequency modulation of 50 Hz or more can be resolved up to 70 dB below the signal level.
    In the log sweep mode the resolution bandwidth changes with frequency giving an effect similar to octave bandwidth sweeps.
    Stability — Within 30 Hz over a 10 min period, at a fixed ambient temperature.
