Best Budget Oscilloscope Under $200 [2026]: 5 Tested, 1 Winner

Why we like it

The FNIRSI DPOX180H is a pocket oscilloscope with surprisingly high bandwidth for the money — 180MHz in something smaller than a deck of cards is legitimately impressive. At $110, you also get protocol decoding, a function generator, and a multimeter in the same device. The hard truth is the 28Kpt memory depth and 2.8-inch screen kill its usefulness for anything beyond quick spot checks — you can glance at a signal, but capturing and analyzing a long serial transaction is off the table. The OWON HDS2202S is better in almost every meaningful way if portability is your goal, but it costs $439 versus this scope's $110. At this price, the DPOX180H is best understood as a capable probe-and-check tool, not a primary bench instrument.

The FNIRSI 1014D is one of the cheapest ways to get a real oscilloscope on your bench. At around $115, it's hard to complain about 100MHz bandwidth and a built-in signal generator — both of which would cost more from Hantek. The honest limitation is the 240Kpt memory depth, which is genuinely painful the moment you try to capture anything longer than a few milliseconds at full sample rate. I'd call this a learning tool, not a precision instrument. If you just want to see what your Arduino signals look like and learn what triggering means, it's a solid starting point. But if you need to trust your measurements or capture serial transactions, save up for a Rigol or Siglent — you'll thank yourself later.

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.
