  • Bemerkung

  • The Model 202D Audio Oscillator is a general purpose oscillator which uses the resistance-tuned circuit to generate alternating current voltages from 2 to 70,000 cycles/sec. This audio oscillator provides a source of voltage for amplifier testing, audio response of transmitters, loud speaker resonance tests, and a voltage source for bridge measurements. It is particularly useful where low frequencies are involved, as in mechanical vibration problems.

    Frequency Range: 2 - 70,000 cycles/sec

    x100 200 - 2000 cycles/sec
    x1000 2000 - 20,000 cycles/sec
    A 7000 - 70,000 cycles/sec
    Calibration Accuracy: ±2%
    Frequency Response: ±1 db 2 to 70,000 cycles/sec. Reference: 1000 cycles/sec, 10 volts across 1000 ohms resistive load. Frequency Stability ±2% under normal temperature conditions, including initial warm-up. ±10 volt line variations change frequency less than ± 0.2% at 1000 cycles/sec
    Power Output: 100 milliwatts into rated load (10 volts across 1000 ohms resistive load)
    Distortion: Less than 1% of rated output from 2 to 70,000 cycles/sec
    Hum: Less than 1% of rated output
    Load Impedance: 1000 ohms (resistive)
    Approximate Internal Impedance: 25 ohms from 50 to 70,000 cycles/sec
