Quick Take
Choosing an oscilloscope often comes down to how you balance bandwidth, portability, and whether you want a new unit or can make do with a used one. The four models here span a listed-price range from $140 to $370.50, so they serve very different workflows.
Pick the FNIRSI 1014D if you want a portable, USB-powered two-channel scope with a signal generator at the lowest listed price. Pick the Tektronix TDS 380 if full 400MHz bandwidth and 2GS/s sampling matter more than a compact size. Pick the Hantek DSO2000 series if you want a new digital scope with a built-in waveform generator and protocol decode. Pick the Hantek DSO2D15 if you want a new 150MHz two-channel storage scope from Hantek sold new in box and are comfortable paying more.

Decision Matrix
- Portable field work or student bench: FNIRSI 1014D - handheld/portable, USB powered, includes probe, 100MHz/1GSa/s.
- New scope with generator and decode: Hantek DSO2000 Series - 2CH plus 1 generator channel, 1GSa/s, protocol decode for UART/I2C/SPI/CAN/LIN.
- High-bandwidth bench diagnostics: Tektronix TDS 380 - 400MHz, 2GS/s, 2-channel real-time scope with math functions and connectivity.
- New 150MHz two-channel storage scope: Hantek DSO2D15 - new in box, 150MHz, designed for accurate waveform analysis.
Hantek DSO2000 Series (DSO2D10)
The Hantek DSO2000 series at $199.97 gives you a two-channel digital scope with a separate waveform generator channel and 1GSa/s real-time sampling. The series name covers both 100MHz and 150MHz bandwidth variants, so you can match the performance to the signals you work on. The scope adds a three-digit voltage display, a six-digit frequency indicator, 32 kinds of auto measurements with statistics, and bus decode for UART, I2C, SPI, CAN, and LIN. That makes it a strong all-around option for anyone who wants protocol analysis and a built-in AWG without moving to the highest price tier. The limitation is that you need to confirm the exact DSO2000 model, because the 100MHz and 150MHz versions are grouped under one series name.
Hantek DSO2D15
At $370.50, the Hantek DSO2D15 is the top-priced model in this comparison, but it is also the one sold as new in box with a clear 150MHz, 2-channel storage scope spec. It offers accurate waveform analysis for diagnostics, a high sampling rate, and a compact unit with multiple measurement functions. If you want a current Hantek 2CH scope without the ambiguity of a grouped series name, this direct model number is the simplest buy. The trade-off is cost: it sits more than $170 above the next Hantek on this list, and the feature set centers on bandwidth and storage scope capability rather than extra generator or decode tools.
Tektronix TDS 380
The Tektronix TDS 380 is the bandwidth leader here with 400MHz and 2GS/s real-time sampling, and it is priced at $195.00. It is a used, tested two-channel digital real-time oscilloscope with a CRT display, autoset, automatic measurements, cursor tracking, wave math, and rear-panel RS-232, Centronics, GPIB, and video output. The 8-bit resolution and dense feature set make it a serious bench instrument for fast-signal work. What holds it back is that this is a used CRT-based unit rather than a new portable model, so its tested condition is the main thing to weigh if you choose it. If you want a brand-new scope, the Hantek options are sold as new.
FNIRSI 1014D
The FNIRSI 1014D is described as handheld/portable and is the lowest-priced model at $140.00. It combines a 100MHz two-channel scope with a DDS signal generator, 1GSa/s sampling, X-Y mode, 240Kpts memory, auto measurement, and USB power. The package includes a 100X probe, which makes it ready for quick signal checks. For students, DIY electronics, and anyone who needs to move between projects, this is the easiest model to carry. The catch is that it is sold as used rather than new, and its 100MHz/1GSa/s spec is lower than the Tektronix's 400MHz/2GS/s. If you need higher bandwidth or a new unit, you would step up to one of the Hantek models.
Final Recommendation by Use Case
- Lowest listed price plus portability: FNIRSI 1014D for $140.00, especially if used condition is acceptable.
- Solid balance of new, generator, and decode: Hantek DSO2000 Series for $199.97, with the caveat that you match the bandwidth variant.
- Maximum bandwidth for bench work: Tektronix TDS 380 for $195.00, accepting a used CRT instrument.
- New 150MHz two-channel scope with a direct model number: Hantek DSO2D15 for $370.50.
If your main goal is a compact, low-cost signal analyzer for learning and field checks, the FNIRSI 1014D gives you the most portable feature set at the lowest listed price. If you need a new scope with a built-in waveform generator and protocol decode, the Hantek DSO2000 Series is the practical middle ground. If 400MHz bandwidth is non-negotiable, the Tektronix TDS 380 delivers it at a price close to the DSO2000 series. And if you simply want a new 150MHz 2CH Hantek with a single clear product number, the DSO2D15 justifies its higher listed price.
