Siglent SDS2354X Plus 4Ch 350MHz 2GSa/s Oscilloscope
The Siglent SDS2354X Plus is the high-bandwidth model of the series — 350 MHz across four channels — for demanding design, power-electronics and validation work. The wider bandwidth resolves fast edges and higher-speed digital signals cleanly, while the 500,000 wfm/s capture rate, up to 200 Mpts of memory and a 10-bit enhanced-resolution mode keep amplitude detail intact for signal-integrity and power-quality measurements that a slower or noisier scope would blur
SDS2354X Plus — 350 MHz, 4 channels
The SDS2354X Plus is the 350 MHz, 4-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 500 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 SDS2354X 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.
Every angle

Who it’s for & best applications
The SDS2354X Plus is the high-bandwidth model of the series — 350 MHz across 4 channels — for demanding design, power and validation work. The extra bandwidth resolves fast edges and higher-speed digital signals cleanly, while a 500,000 wfm/s capture rate, up to 200 Mpts of memory and a 10-bit ERES mode keep detail intact for signal-integrity and power-quality measurements. On-instrument Bode plot, optional power analysis, a 16-channel MSO, a 50 MHz generator and serial-decode licences make it a complete analysis bench — and it can still be license-upgraded to a full 500 MHz.
