Siglent SDS2102X Plus 2Ch 100MHz 2GSa/s Oscilloscope
The Siglent SDS2102X Plus is the affordable two-channel doorway into the third-generation 2000-series — a general-purpose oscilloscope that packs far more capability than its price suggests. Where budget scopes cut the display, memory or capture rate, the X Plus keeps all three: a fast 500,000 wfm/s waveform capture rate with 256-level intensity grading to reveal glitches and detail, up to 200 Mpts of memory for long records at full sample rate, and an 8-bit front end with a 10-bit enhanced-resolution mode for cleaner low-level measurements.
SDS2102X Plus — 100 MHz, 2 channels
The SDS2102X Plus is the 100 MHz, 2-channel model of Siglent’s third-generation SDS2000X Plus series — a feature-rich, general-purpose oscilloscope with a deep toolset at a real-world bench budget. An 8-bit front end with a 10-bit enhanced-resolution mode keeps low-level measurements clean, and Siglent’s SPO technology gives a fast, detailed display.
Performance backs it up: 2 GSa/s sampling, up to 200 Mpts of memory and a 500,000 wfm/s capture rate, on a 10.1" capacitive multi-touch display. Built-in Bode plot, an optional power-analysis package, a 16-channel MSO and a 50 MHz generator make it a complete bench — and its bandwidth is license-upgradable to 350 MHz, so the instrument grows with your work.
More scope per euro than anything in its class
500,000 wfm/s and 256-level grading mean glitches show up on screen — not after an hour of guessing.
I²C, SPI, UART, CAN and LIN trigger & decode ship as standard — features many competitors licence separately.
Bandwidth, MSO, a 50 MHz generator and power analysis all activate by licence — buy the scope once, upgrade when you need it.
Scope, Bode plotter, protocol analyzer, generator and logic analyzer in a single 10.1" touchscreen instrument.
Six tools in one instrument
Everything below runs on the SDS2102X Plus itself — no PC software required.
Bode plot
Drive the built-in generator or any Siglent SDG and plot gain and phase versus frequency — power-supply loop response and filter characterisation on the instrument.
Power analysis
Optional power-analysis software measures switching loss, harmonics, ripple, modulation and slew rate for switching supplies and power devices.
Mixed-signal (MSO)
Add the SPL2016 Plus 16-channel logic probe to view and decode 16 digital channels alongside the analog inputs.
Built-in 50 MHz AWG
An optional 50 MHz arbitrary/function generator licence turns the scope into a stimulus-and-measure bench in one box.
Serial decode
Trigger and decode I²C, SPI, UART, CAN and LIN as standard — with colour-coded bus overlays and list view. CAN FD, FlexRay, I²S and 1553B add on.
Deep memory & history
200 Mpts of record plus Sequence and History modes capture long, rare events at full sample rate — then zoom, search and navigate to the fault.

Who it’s for & best applications
The SDS2102X Plus is the affordable 2-channel entry into Siglent’s third-generation 2000-series — a feature-rich, general-purpose oscilloscope for education, service and everyday electronics. Its SPO front end delivers a fast 500,000 wfm/s capture rate with 256-level intensity grading, so glitches and detail are easy to see, while up to 200 Mpts of memory captures long events at full sample rate and a 10-bit ERES mode keeps low-level measurements clean. Built-in Bode plot, an optional power-analysis package, MSO and a 50 MHz generator, plus a 10.1″ multi-touch display, make it a complete bench — and its bandwidth is license-upgradable to 350 MHz.
