Quick Take
Choosing a two-channel oscilloscope usually comes down to whether you value bandwidth, extra built-in tools, or a lower listed price. These four options span a wide price range, with a used Tektronix at the low end and a new in box Hantek at the high end. They include a signal generator, a signal spectrum analyzer, and a CRT-based bench unit. If you're shopping for a 2CH scope and want to also look at signals in the frequency domain, the FNIRSI DPOS350P is the one listing that puts both a signal generator and a spectrum analyzer in the product title.
Listed Price Comparison
| Model | Listed Price | Price Bar | Key Specs |
|---|---|---|---|
| Hantek DSO2000 Series | USD 199.97 | 2CH+1CH, 100/150MHz, 1GSa/s, 25MHz AWG | |
| Hantek DSO2D15 | USD 370.50 | 150MHz, 2CH, digital storage | |
| FNIRSI DPOS350P | USD 225.00 | 350MHz, 2CH, signal generator, spectrum analyzer | |

Decision Matrix
- Choose the Hantek DSO2000 series if you want a new scope with a built-in arbitrary waveform generator.
- Choose the Hantek DSO2D15 if you want a new in box storage oscilloscope with a specific model number.
- Choose the FNIRSI DPOS350P if you want one unit that handles signal generation, spectrum analysis, and waveform viewing.
- Choose the Tektronix TDS 380 if you want a used bench scope with high bandwidth and GPIB/RS-232 connectivity.
Product Notes
Hantek DSO2000 Series
The Hantek DSO2000 series is a new two-channel oscilloscope listed at USD 199.97. The title points to 100/150MHz analog bandwidth, 1GSa/s real-time sampling, and a 25MHz arbitrary waveform generator. That's a handy pairing for anyone who needs a clean test signal without a separate bench generator. The description also mentions 8M memory depth, a vertical range from 2mV/div to 10V/div, and 32 automatic measurements. The built-in 25MHz generator is described for the DSO2D10 and DSO2D15 variants, so this listing's series-level name may cover more than one model. Choose it if you want a new scope and waveform generator in one box; just know the bandwidth is in the 100/150MHz class rather than the 400MHz range of the Tektronix.
Hantek DSO2D15
Priced at USD 370.50, the Hantek DSO2D15 is the highest-priced chalk in this group and arrives as a new in box digital storage oscilloscope with 150MHz bandwidth and two channels. The listing highlights a high sampling rate, clear display performance, and multiple measurement functions. Interestingly, the DSO2000 series listing notes that the 25MHz arbitrary waveform generator is built into both the DSO2D10 and DSO2D15 variants, even though the DSO2D15 title doesn't spell it out. So you may be getting a generator plus a specific model identifier. The trade-off is the price: it's the most expensive of the four, and the title itself only lists 150MHz/2CH without the extra test tools shown on the FNIRSI.
FNIRSI DPOS350P
The FNIRSI DPOS350P is listed at USD 225.00 and described as a 4-in-1 unit: a 350MHz two-channel oscilloscope, signal generator, and spectrum analyzer. Attributes list a 7-inch 1024x600 display, 1GSa/s real-time sampling, a hardware bandwidth limit of 150M/20M, and high resolution mode from 8 to 16 bits. The open-box condition means the unit is not factory sealed, so it suits someone willing to accept that status for a less expensive multi-function tool. The 350MHz headline in the title is higher than the 100/150MHz claims on the two Hantek listings, though the attributes also list 150M/20M hardware bandwidth limits. Choose it when you want signal generation, spectrum analysis, and waveform viewing in one unit.
Tektronix TDS 380
The Tektronix TDS 380 is the lowest-priced entry at USD 195.00. It's a used two-channel digital real-time oscilloscope with 400MHz bandwidth and 2GS/s real-time sampling, and the title says Tested. Attributes include CRT display, Autoset, measure menu, hardcopy, math functions, RS-232, Centronics, GPIB, and video output. For someone who needs a benchtop instrument with serial and GPIB connectivity, that's a rare combination at this price. The limitation is the used condition and CRT display, which won't match the modern LCD, compact size, or built-in generator/spectrum analyzer of the newer units.
Final Recommendation by Use Case
If you want two channels and a waveform generator in a new package, the Hantek DSO2000 series is the most direct fit. If you prefer a new in box 150MHz storage scope with a specific model number, the Hantek DSO2D15 is the option. For a 4-in-1 unit that adds signal generation and spectrum analysis, the FNIRSI DPOS350P pairs that with a 350MHz claimed bandwidth. If your priority is maximum bandwidth and legacy bench connectivity, the used Tektronix TDS 380 has 400MHz bandwidth plus GPIB/RS-232 at the lowest listed price. Each unit has a different balance, so choose based on whether you need new packaging, built-in waveform generation, spectrum analysis, or a dedicated CRT scope with serial and GPIB ports.
