    LAG-120A AUDIO GENERATOR GENERAL DES CRIPTION Uses The LAG-120A is a wideband audio generator with sine and square output waveforms. Sine wave signals are available with a distor of less than 0.4%. Square waves with fast rise time can be used for circuit performance Synchronizing the output frequency is accomplished checks.

R. is connected across the output of the amplifier, or test circuit. It should be non-inductive and have a wattage rating at least twice the expected maximum power output.
  • Page 7 Frequency Response The frequency response of amplifier is determined applying a constant voltage to the amplifier input. This voltage is chosen so that the amplifier is operated below the overload point. Set the reference frequency 1kHz or 400Hz, and set ATTENUATION and VARI- ABLE for suitable amplifier output.

    signal of exactly 1000Hz is applied, the oscillator will automatically lock in at 1000Hz. Thus, high accuracy can be achie v ed with the use of a precision frequency standard. In another application, a distorted waveform can be "purified", or filtered, by passing it through the oscillator.

RANGE switch x1k, and the dial at "I" Set the waveform switch at sine. 2. The counter reading should be 1000Hz within ±3% (or between 9 7 0 and 1030Hz). If considerably off, then set the dial so that the counter reads 1000Hz.
