GW Instek GFG-8020G Function Generator — Built-In 4-Digit Frequency Counter
Multi-waveform function generator with 0.2 Hz–2 MHz range and integrated LED frequency counter
Overview
The GW Instek GFG-8020G is a versatile function generator capable of producing square, triangle, sine, ramp, and pulse waveforms across a 0.2 Hz to 2 MHz range. It features a large 0.5" 4-digit LED display paired with a built-in frequency counter for measuring internal oscillation frequency, along with coarse and fine tuning controls for precise signal setup. With VCF input, variable DC offset, and selectable TTL/CMOS pulse output, this unit is a practical bench instrument for general electronics testing, calibration, and lab work.
Key Features
- Wide frequency range: Generates waveforms from 0.2 Hz to 2 MHz for a broad range of test applications.
- Multiple waveform types: Outputs square, triangle, sine, ramp, and pulse waveforms from a single instrument.
- Built-in frequency counter: Integrated counter measures internal oscillation frequency directly on the front panel.
- Large LED display: 0.5" 4-digit LED readout for clear frequency reading at a glance.
- Coarse and fine tuning: Dual-control tuning allows for both quick range selection and precise frequency adjustment.
- Flexible signal conditioning: Includes VCF (voltage-controlled frequency) input, variable DC offset, and selectable TTL or CMOS pulse output.
- Adjustable DC offset: Variable offset control from +10V to -10V open circuit, or +5V to -5V into a 50-ohm load.
