For anyone working with waveform and signal measurement, choosing between two digital oscilloscopes in the $150 to $200 range means deciding what you actually need to see on your bench. One is a used real-time scope from Tektronix; the other is a new model from Hantek with extra capabilities. With roughly $50 separating them, the right pick comes down to condition, features, and whether you already own a signal source.
Quick verdict
If you want the lowest-cost way to view two clean waveforms and you don't mind a used unit, the Tektronix TDS220 is the practical pick. If you need a new scope that also gives you a built-in waveform generator, deep memory, and bus decoding, the Hantek DSO2000 series justifies its higher price.
Price and spec comparison
| Feature | Tektronix TDS220 | Hantek DSO2000 Series |
|---|---|---|
| Price | $149.99 (used) | $199.97 (new) |
| Channels | 2 | 2CH+1CH |
| Bandwidth | 100 MHz | 100/150 MHz series |
| Sampling rate | 1 GS/s | 1 GSa/s |
Where each wins
The Tektronix wins on price and simplicity. For the lower cost, you get a straightforward real-time scope, and the Tektronix description notes that a signal generator check produced clear waveforms on both channels. It's the easier choice if you're doing basic waveform viewing and don't need advanced protocol analysis.
The Hantek wins on features and new condition. For the extra outlay, you get a brand-new scope with a deeper measurement toolkit and more trigger options. If you need a signal source and a scope in one instrument, that extra spend buys real capability.
Tektronix TDS220
The Tektronix TDS220 is the more affordable of the two at $149.99, and it delivers exactly what the model name promises: 100 MHz bandwidth, 1 GS/s sampling, and two digital real-time channels. The description notes that the unit was connected to a signal generator and produced a clear wave on both channels, which gives some confidence for basic waveform checks. Choose it if you want a straightforward 2-channel scope and you're comfortable with a used instrument. The main limitations are the used condition, the missing BNC cable, and the possibility that it may need calibration before precision work. For under $150, it's a functional entry point for seeing two signals at once.
Hantek DSO2000 Series
The Hantek DSO2000 series is the new-build option at $199.97, and it packs a large feature set into a compact digital platform. Beyond the 2CH+1CH channel arrangement and 1 GSa/s sampling, the description highlights an 8M memory depth, 32 auto measurements, a wide trigger menu, bus decoding, and a built-in 25 MHz waveform generator on models like the DSO2D10. That makes it an attractive choice if you need a scope and a signal source on the same bench without buying a separate generator. The main tradeoff is the higher price relative to the Tektronix. The DSO2D10 model name sits within a series that lists 100/150 MHz bandwidth, so the figure spans the product line. For $199.97, you get a new, far more versatile instrument.
Final choice by use case
Choose the Tektronix TDS220 if your priority is keeping spending down and you're comfortable with a used instrument. Choose the Hantek DSO2000 series if you want a new scope with extra generation and analysis capabilities built in.
