If you're choosing an oscilloscope that also works as a signal generator, the first decision isn't just bandwidth - it's whether you need a bench-style display, a handheld unit, or a multimeter built in. This comparison covers four FNIRSI listings: two versions of the same 1014D H0V2, the DS215H handheld, and the 2C23T 3-in-1. Listed prices span from $75.99 to $158.00, so the choice comes down to how much screen, bandwidth, and portability you actually need.
Quick take
The FNIRSI 1014D H0V2 gives you a 7-inch TFT LCD, 100MHz analog bandwidth, two channels, and a DDS signal generator at $158.00. The used version of the same model shares those specs and the same listed price, but the listing describes an opened-package customer-return unit. The FNIRSI DS215H is a handheld 2-in-1 with a 50MHz analog bandwidth and a 3.5-inch IPS HD color screen, listed at $86.99. The FNIRSI 2C23T is a 3-in-1 oscilloscope, multimeter, and signal generator with a 20MHz maximum bandwidth, listed at $75.99.

Decision matrix
| Your priority | Consider this model | Why |
|---|---|---|
| Large screen and 100MHz bandwidth | FNIRSI 1014D H0V2 | 7-inch TFT LCD, two channels, 100MHz analog bandwidth, built-in signal generator |
| Portability and a 50MHz scope | FNIRSI DS215H | Handheld, 3.5-inch IPS screen, 1500mAh battery, built-in signal generator |
| Multimeter + oscilloscope all-in-one | FNIRSI 2C23T | 3-in-1 tool with dual channels, 20MHz maximum bandwidth, and probe included |
| Same 1014D specs and open-package condition | FNIRSI 1014D H0V2 (Used) | Same model and listed price as the new unit, but packaging is opened and it is described as a return |
Product notes
FNIRSI 1014D 7-inch LCD 2 Channel Signal Generator Digital Storage Oscilloscope H0V2 (New)
Choose this if you want the largest display in the group and the highest analog bandwidth. The 1014D H0V2 is a desk-style two-in-one oscilloscope and signal generator with a 7-inch TFT LCD, two channels, and 100MHz analog bandwidth. The built-in DDS function signal generator supports 14 standard function signals, and the chopping output can store up to 1000 customized cut-off signals. A high-voltage protection module handles up to 400V continuous voltage, which is useful when working with probes and higher-voltage signals. At USD 158.00, it is the highest listed price in this set. The main limitations are the bench-oriented size and the price - it is not a handheld model and it costs more than the DS215H or 2C23T listings.
FNIRSI 1014D 7-inch LCD 2 Channel Signal Generator Digital Storage Oscilloscope H0V2 (Used)
The used listing carries the same product name and specifications as the new 1014D H0V2: two channels, 100MHz analog bandwidth, 7-inch TFT LCD, USB picture export, and the built-in DDS signal generator. It is listed at the same USD 158.00 price. The listing describes the unit as a customer-return product that is almost new with packaging opened, and it explicitly says not to buy if that bothers you. So the trade-off is condition, not capability. If you prefer a factory-fresh unit, the new listing is the straightforward choice at the same listed price; if opened packaging is acceptable to you, this version gives you the same feature set for the same money.
FNIRSI DS215H Oscilloscope Handheld Dual-Channel 2-IN-1 Digital Signal Generator
The FNIRSI DS215H is the portable option in this group. Listed at USD 86.99, it combines a handheld dual-channel oscilloscope with a built-in signal generator. It offers a 50MHz analog bandwidth with up to 250MS/s sampling rate, plus a 3.5-inch IPS HD color screen and a 1500mAh battery for mobile use. The signal generator produces 13 waveform outputs in the 0-50kHz range with a 1Hz step, and the device supports screenshot saving so you can review captured waveforms on the screen. The trade-off is the smaller display and narrower bandwidth compared with the 1014D H0V2. If portability matters more than maximum measurement headroom, the DS215H is a strong fit.
FNIRSI 2C23T 3-in-1 Digital Oscilloscope Multimeter Function Signal Generator US
The FNIRSI 2C23T is a 3-in-1 tool that combines a digital oscilloscope, multimeter, and signal generator in a handheld form factor, listed at USD 75.99. It has dual channels, a 20MHz maximum bandwidth, and the listing includes a probe. The description highlights isolated channels to avoid interference between the two inputs, along with trigger modes including automatic, single, and conventional. The low listed price makes it the most approachable entry point in this set if you want a compact all-in-one for waveform viewing plus multimeter work. The limitation is the 20MHz bandwidth, which is narrower than both the DS215H and the 1014D H0V2, so it is best suited to lower-frequency signals.
Final recommendation by use case
If your priority is a bench oscilloscope with a large screen and 100MHz bandwidth, the new FNIRSI 1014D H0V2 at USD 158.00 is the model to start with. If you need something handheld and portable with a 50MHz bandwidth and a signal generator, the FNIRSI DS215H at USD 86.99 is the better fit. If you want a multimeter-style all-in-one at the lowest listed price, the FNIRSI 2C23T at USD 75.99 is the practical choice. For shoppers who want the 1014D H0V2 feature set and are comfortable with an opened-package return, the used listing offers the same model and specs at the same listed price as the new one.
