  • Notes

  • ADVANTAGES:
    No zero setting, Great stability, Constant output, Wide frequency range, Logarithmic scale, Low distortion, Light weight

    USE THEM FOR:
    Amplifier testing, Broadcast transmitter audio response, Source of voltage for bridge measurements, Modulating signal generators, Supersonic voltage source, Driving mechanical systems Synchronizing pulse generators, Loud speaker resonance tests

    Frequency Range:
    Ax1 6 cps – 20 cps
    Bx1 20 cps – 60 cps
    Ax10 60 cps – 200 cps
    Bx10 200 cps – 600 cps
    Ax100 600 cps – 2000 cps
    Bx100 2 kc – 6 kc

    Stability:
    Under normal conditions the frequency drift is less than ±2% even including initial warm-ups. Plus or minus 20% line voltage variations change the frequency less than ±0.2%, at 1 kc. No zero setting is necessary on these oscillators. If the ranges are standardized against a suitable frequency standard from time to time, accuracy better than 1% can be maintained.

    Output:
    Model 200I will deliver 100 milliwatts or 10 volts into a 1000 ohm load. The internal impedance of the output amplifier is about 50 ohms at 1000 cps.

    Frequency Response:
    The frequency response is plus or minus one decibel from 6 cps to 6,000 cps.

    Distortion:
    less than 1 % above 10 cps, and only slightly more than this at lower frequencies.

    Hum Voltage:
    the hum voltage is less than 0.1% of maximum output voltages.
