Siglent SDS824X HD 4CH 200MHz 12bit Oscilloscope
SIGLENT’s new SDS824X HD series high resolution digital storage oscilloscope is based on 2 GSa/s, 12-bit Analog-Digital Converters and front ends with excellent noise floor performance. With a 200MHz bandwidth, and a maximum record length of 100 Mpts, and has 4 analog channels + 16 digital channels mixed signal analysis ability.
SDS824X HD — 200 MHz, 4 channels, 12-bit
The SDS824X HD is the 200 MHz, 4-channel model of Siglent’s SDS800X HD series — the most affordable 12-bit oscilloscope in the range, bringing high-resolution acquisition to the bench, lab and classroom. The 12-bit ADC and a quiet 70 µVrms front end resolve small signals and ripple with far less noise than an 8-bit scope.
It pairs that resolution with 2 GSa/s sampling, up to 100 Mpts of memory and a 120,000 wfm/s capture rate, a 7" capacitive multi-touch display, and built-in Bode plot, power analysis and a 2 Mpts FFT. Standard serial decode (incl. CAN FD, FlexRay & I²S), an optional 16-channel logic probe and a 25 MHz generator make it a complete, budget-friendly bench.
Analysis tools built in
12-bit high resolution
A true 12-bit ADC reveals fine detail and small signals with 16× less quantisation noise than an 8-bit scope, on a front end with a 70 µVrms noise floor.
Bode plot & power analysis
Built-in frequency-response (Bode) plotting with a Vari-level mode for control-loop response, plus optional power-analysis tools.
2 Mpts FFT
A hardware-accelerated 2 Mpts FFT with Normal/Average/Max-hold modes, multiple windows and peak markers turns the scope into a capable spectrum tool.
Advanced math
Four math traces with +, −, ×, ÷, FFT, integrate, differentiate and square-root, plus a formula editor for complex operations.
Who it’s for & best applications
The SDS824X HD is the most capable model in the entry line — 200 MHz across 4 channels — a versatile all-rounder for benches that need both speed and multiple channels at once. Four channels and the higher bandwidth follow several fast signals, power rails and serial buses together, while 12-bit resolution keeps fine detail visible throughout. Backed by 100 Mpts memory, a 7″ capacitive touch display and a 120,000 wfm/s capture rate, it handles demanding multi-channel embedded, power and mixed-signal work, and grows further with an optional 16-channel logic probe and a 25 MHz waveform generator.
