    The solid-state HP Model 203A Low-Frequency Variable-Phase Funciton Generator provides two transient-free low-distortion square and sinusoidal test signals particularly useful for a wide variety of low-frequency applications. Field and laboratory testing of servo, geophysical, medical and high-quality audio equipment become practical when using the 203A.
    The 203A frequency range of 0.005 Hz to 60 kHz is covered in 7 overlapping bands (2 additional ranges available on special order, offering frequency range to 0.0005 Hz). Accurate ± 1% frequency setting is provided by 180 dial divisions. A vernier drive allows precise adjustment.
