Digilent Analog Discovery 3 vs Hantek 6022BE

Digilent Analog Discovery 3

The Digilent Analog Discovery 3 isn't really an oscilloscope — it's a multi-instrument lab that happens to include a 2-channel oscilloscope alongside 13 other tools. The 16-channel logic analyzer is its killer feature for embedded work: you can monitor SPI, I2C, GPIO pins, and PWM outputs simultaneously, something a 4-channel scope simply cannot do. WaveForms software is genuinely excellent — one of the best oscilloscope software experiences on any platform. As a pure oscilloscope, the 125MSa/s sample rate and 32Kpt memory are real limitations that you'll notice on any non-trivial analog signal. This is the right tool if you need a logic analyzer AND a scope AND a function generator and can only buy one device — especially for embedded development and student labs. If you primarily need to measure analog signals or capture long waveforms, a dedicated benchtop scope will serve you better.

Hantek 6022BE

The Hantek 6022BE is the bare minimum USB oscilloscope — and I mean that literally, not as a compliment. At ~$65, you get 2 channels and 20MHz of bandwidth piped through your laptop screen, which is enough to verify that a PWM signal exists or check audio frequencies. The 20MHz limit is genuinely painful: you can't reliably see rise times on 3.3V Arduino signals, and anything SPI-related at normal speeds is already at the edge of what this scope can resolve. Skip the official software and use OpenHantek instead — it's actively maintained and much better. If you can stretch to the Analog Discovery 3, the difference is night and day. If you're truly at a $65 ceiling and just need to verify signals exist, this will do — but you'll outgrow it fast.
