The 1Hz–500kHz DDS signal generator is small but powerful, easy to use and carry; It runs on USB power, so you don't need batteries or an AC/DC adapter
Pair it with an oscilloscope to test/debug electronic circuits, check audio amplifier frequency/impulse responses, or calibrate the oscilloscope's sweep time factor
Its square waveform works great for tuning oscilloscope attenuators and probe impulse responses. There's also a toggleable filter to get the best sine wave and pulse wave output
The RF signal generator generates sine, square, triangle, and positive/negative sawtooth waveforms, making it a go-to tool for professionals
