1. Model 4005 PRODUCT DESCRIPTION
1-1. Introduction
The 4005 is designed to be used as a FUNCTION GENERATOR, SWEEP GENERATOR, PULSE
GENERATOR and a FREQUENCY COUNTER, offering a wide range of applications in both analog
and digital electronics such as engineering, manufacturing, servicing, education and hobbyist fields.
VCF (voltage controlled frequency) produces precision sine, square and triangle waves over the
0.05Hz to 5MHz for sub-audible, audio, ultrasonic and RF applications. A continuously variable DC
offset allows the output to be injected directly into circuits at the correct bias level.
Variable symmetry of the output waveforms converts the instrument to a pulse generator capable of
generating rectangular waves or pulses, ramp or sawtooth waves and skewed sine waves of variable
duty cycle. The sweep generator offers linear sweep with variable sweep rate and sweep width up to
100:1 frequency change. The frequency response of any active or passive device up to 5 MHz can be
determined.
