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:
Range 1: 7 cps – 70 cps
Range 2: 70 cps - 700 cps
Range 3: 700 cps - 7 kc
Range 4: 7 kc – 70 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.

Output:
The Model 200D 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 output voltages is constant within plus or minus one decibel from 7 cps to 70 kc.

Distortion:
The total rms distortion contained in the waveform is less than 1%; distortion from 10 cps to 20 kc.

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