The BDD FD100 DDS Function Generator is a compact, versatile signal source designed for electronics testing, development, calibration, and educational use. Built around Direct Digital Synthesis (DDS) technology, it delivers stable, accurate frequency generation with fine 1Hz resolution, making it well suited for both bench work and portable applications.
This function generator supports a wide range of output waveforms, including sine, square, triangular, forward sawtooth, and reverse sawtooth waves, allowing it to meet the needs of analog, digital, and mixed-signal testing. The sine wave output provides flat and stable amplitude up to 200kHz, ensuring clean signals for precision measurements. Beyond 200kHz, the signal remains usable, with expected amplitude roll-off typical of compact DDS designs.
The FD100 is particularly useful for oscilloscope applications, such as scan time calibration, probe compensation, and attenuator testing. Its waveform output is clean and consistent, making it suitable for adjusting oscilloscope probes and verifying signal paths in test equipment.
An integrated switchable filter enhances output quality, especially for sine and square waves, reducing unwanted harmonics and improving waveform clarity when required. Users can easily enable or disable the filter depending on the application, offering flexibility between signal purity and bandwidth.
With a maximum output amplitude of 10V peak-to-peak, selectable DC offset, and a standard 50-ohm output impedance, the FD100 integrates seamlessly into typical laboratory and DIY setups. Its small size, lightweight ABS enclosure, and low power requirements make it easy to carry and power from a 5V DC adapter or a 3.7V lithium battery, ideal for mobile testing or field work.
Designed for simplicity and durability, the BDD FD100 combines multiple functions into a single, easy-to-use instrument-making it an excellent choice for hobbyists, students, technicians, and engineers who need a reliable and affordable signal generator.
