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

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.

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.

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.
