  • Notes

  • Standard Sine Wave Source, Type LO.800A

    The device produces high-quality sine waves even at very low frequencies, below 10 Hz (cycles per second).

    • It utilises two high-frequency (H.F.) oscillators with minimal "pull-in" between them to generate the low-frequency output.
    • The waveform quality is described as "almost perfect" across its entire frequency range.
    • The output voltage remains consistent within a few percent throughout the frequency range.
    • A three-range Output Voltmeter incorporated: 0 -250, 0-50, & 0 -10.
    • Four output impedances, 5,000, 1,000, 600, and 15 ohms.
    • Output up to 5 watts, 10 cps.

    Available in 3 models.

    0 – 15,000 cps
    0 – 25,000 cps
    0 – 50,000 cps
