Fourier Synthesizer (Pasco)

This is a signal generator that gives two 440 Hz fundamental outputs and the first 8 harmonics of the fundamental. Each harmonic has variable phase and amplitude, and has a frequency accurate to better than 0.1%.

1. Select the frequencies desired with the IN/OUT switches
2. Select the wave shapes of the fundamental with the appropriate switches
3. The usual output is labelled "10K OUTPUT". Be sure to keep the ground terminals the same in all components.
4. Adjust the amplitude and phase for each frequency with the appropriate switches and knobs in each column.
5. The TRIGGER OUTPUT is intended for an oscilliscope trigger, if desired.
6. Turn the unit ON
7. An 8ohm output is available for connections with speakers.

NOTE: Push the RESET button each time before taking measurements.
