For this Budget Tools Review, I’ve had the chance to try out the Yeapook ADS1014D scope/generator. TL;DR it’s not great, however, can be had for well under $200. Perhaps it could be a good value with some important caveats that I’ll outline in this review article/video.

Taking a look at the device’s listed stats, its 240kbit memory depth is a bit thin, and its 50mV/division sensitivity is on the high side. However, compromises should be expected for this level of instrument. On the other hand, my testing of the unit only went so far (e.g. my signal generator’s 25MHz limitation), and a fair question would be: How does the ADS1014D actually perform at the higher end of its stated abilities?

Long story short, the device is mostly acceptable for measuring frequencies up to 30MHz, at which point readings start to degrade significantly on the way up to 100MHz.

For under-30MHz measurements, and/or relatively low-speed signal generation, it could be useful. What’s bothersome, however, is that its abilities appear to be grossly overstated per Wong’s video. That being said, for critical applications it would be tough to trust such a device if you’re not sure it lives up to its claims.

After that brilliant advertisement, we are giving one away, and you can enter for a chance to win below. At potentially $0 it is indeed an excellent value, especially for students, or in other applications where a poor reading isn’t the end of the world. At normal retail prices, it might be better to consider an OWON portable scope, or a headless device like Digilent’s Analog Discovery 3.
