INTRODUCTION The M O D E L F G - 2 7 2 Sweep/Function Generator provides from 0.5 Hz ( 2 seconds) to 50 Hz (20 milliseconds). Sweep control is implemented by applying sweep signal functions of a function generator, pulse generator, and to the V C F connector from an external device.
PRECAUTIONS Do not use the F G - 2 7 2 Function Generator under Do not repeat switching on and off the Generator, the following conditions : Places exposed to the direct sun light Follow the instructions in section " M A I N T E N A N C E Very hot and humid rooms if the supply voltage is to be changed.
