Siglent SDS1202X HD 2CH 12bit 200MHz Oscilloscope
SIGLENT’s SDS1202X HD 2 channel 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 bandwidth of 200 MHz, it has a maximum record length of 200 Mpts, and display 2 analog channels + 16 digital channels mixed signal analysis ability.
SDS1202X HD — 200 MHz, 2 channels, 12-bit
The SDS1202X HD is the 200 MHz, 2-channel model of Siglent’s SDS1000X HD series — an affordable 12-bit oscilloscope that brings high-resolution acquisition to the bench, lab and classroom. The 12-bit ADC resolves small signals and ripple with far less noise than an 8-bit scope, and a quiet front end keeps measurements trustworthy.
It pairs that resolution with 2 GSa/s sampling, up to 100 Mpts of memory and a 120,000 wfm/s capture rate, a 10.1" capacitive multi-touch display, and built-in Bode plot, power analysis and FFT. Standard serial decode (incl. CAN FD & FlexRay), optional 16-channel MSO 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.
Bode plot & power analysis
Built-in frequency-response (Bode) plotting and power-analysis tools — loop response, ripple and harmonics on-instrument.
2 Mpts FFT
A deep 2 Mpts FFT turns the scope into a capable spectrum tool for spotting noise and harmonics.
Math & analysis
Four math traces with a formula editor, plus Search, Navigate, History, Mask Test and Counter.
Who it’s for & best applications
The SDS1202X HD doubles the bandwidth to 200 MHz in a 2-channel format — for faster edges and higher-frequency signals where two channels suffice, with the 12-bit resolution to still see fine detail. The extra bandwidth captures quicker rise times, higher clock rates and faster switching cleanly, while the deep FFT extends spectral analysis further up the frequency range. Backed by a 10.1″ capacitive touch display, deep memory and a 120,000 wfm/s capture rate, it suits faster development, validation and repair work and remains ready to expand with an optional 16-channel logic probe and a 25 MHz waveform generator.
