16. Hewlett-Packard model No. 3325A. This generator was chosen for convenience. Any signal source with resolution and reproducibility of 1 mHz and 1 mV would be sufficient. Because the oscillator acts as a low pass filter with a corner frequency at about 0.2 Hz, requirements on harmonic distortion are more modest.
