## Description

One of the most versatile pieces of test equipment you can own. It provides a consistent waveform output, useful for checking response of audio circuits etc. This digital function generator has an in-built frequency counter, as well as functioning as a standard waveform generator with sinusoidal, triangle and square wave outputs. DC offset adjustment allows the waveform to be shifted above or below 0V. Output amplitude is adjustable from 0 to 10V p-p via front panel control, with a switchable -20dB attenuator. Output frequency is adjustable between 0.03Hz to 3MHz via front panel rotary dial over seven ranges. It has an external sync output for synchronising other test equipment to the signal generator, such as CROs and logic probes. This allows observation of phase shifts relative to the signal generator output. It also features a 3 MHz 4 digit frequency counter with external BNC counter input. A self calibration mode ensures excellent accuracy at all times.
