An Analog function generator producing a biasing current for the permeability-tuned master oscillator of the zero gradient synchrotron is described. It produces the bias function with a precision of ± 0.02 per cent and is capable of delivering about 3 amperes of current into a predominantly resistive load of a quarter of an ohm. The input information to the function generator is obtained from proton accelerator parameters such as the magnetic guide field Bg and ¿g and the guide magnet current Ig and ¿g. The total bias function is obtained as a result of adding outputs from the 1) Bg read-out, 2) hump generator, and 3) biased diode network. A specially developed electronic system and an analog-to-digital converter have been employed to make static and dynamic measurements with a view to determining the precision of the function generator.
