  1. 1. SIGNAL GENERATORSignal Generator Fundamentals
  2. 2. AF SINE AND SQUARE WAVE GENERATOR FRONT PANNEL CONTROLS: 1. Frequency selector 2. Frequency Multiplier 3. Amplitude Multiplier 4. Variable amplitude 5. Symmetry Control 6. Amplitude 7. Function Generator 8. Output Variable 9. Sync 10. ON-OFF
  3. 3. Specifications: Frequency - 10Hz to 1MHz, 5decades. Sine wave - 5mV to 5V(rms). Square wave – 0-20V(peak). Square wave symmetry is adjusted from 30% - 70%. O/p is taken from push-pull amplifier with low o/p impedance. At 220V,50Hz, AF Signal generator requires 7W of power only.
  4. 4. Function Generator:• Diff waveform of adjustable frequency• Various o/p at same time.• Capability of Phase lock.• Square wave- for testing linearity measurement• Sawtooth- to drive horizontal deflection amplifier of an oscilloscope.• Frequency Control
