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 HD — 350 MHz, 4 channels, 12-bit
The SDS2354X HD is the 350 MHz model of Siglent’s mid-range SDS2000X HD series — a 4-channel, 12-bit oscilloscope that brings high-resolution acquisition and a full analysis toolset to a real-world bench budget. Its 12-bit ADC and low-noise front end resolve small signals, ripple and subtle distortion that an 8-bit scope buries in quantisation noise.
Performance backs up the resolution: 2 GSa/s sampling, up to 200 Mpts of memory and a 100,000 wfm/s capture rate, on a 10.1" capacitive multi-touch display. Built-in Bode plot, power analysis and 2 Mpts FFT, plus an optional 16-channel MSO and built-in 25 MHz generator, make it a complete bench — and its bandwidth is license-upgradable up to 500 MHz, so the instrument grows with your work.
Analysis tools built in
12-bit high resolution
A true 12-bit ADC reveals fine detail, small signals and low-level ripple with far less quantisation noise than an 8-bit scope.
Bode plot
Built-in frequency-response (Bode) plotting characterises power-supply loop response and filters directly on the instrument.
Power analysis
On-instrument power-analysis tools measure switching loss, harmonics, ripple and efficiency without a PC.
Built-in waveform generator
An optional built-in 25 MHz arbitrary/function generator adds stimulus without an extra box on the bench.
Who it’s for & best applications
The SDS2354X HD is the high-bandwidth model of the mid-range line — 350 MHz across 4 channels with 12-bit resolution and deep memory — for demanding design, power and validation work. The extra bandwidth resolves fast edges and higher-speed digital signals cleanly, while the 12-bit ADC and quiet front end keep amplitude detail intact for signal-integrity and power-quality measurements. On-instrument Bode plot, power analysis and deep FFT, plus an optional 16-channel MSO, 25 MHz generator and serial-decode licenses, make it a complete analysis bench — and it can still be license-upgraded to a full 500 MHz.
