Siglent SDS3034X HD 4CH 12bit 350MHz Oscilloscope
SIGLENT’s SDS3034X HD series Digital Storage Oscilloscope has a bandwidth of 350 MHz and has 12 bit ADCs with sample rate up to 4 GSa/s, maximum record length of 400 Mpts/ch, and it will display up to 4 analog channels + 16 digital channels for high performance mixed signal analysis.
SDS3034X HD — 350 MHz, 4 channels, 12-bit
The SDS3034X HD is the 350 MHz model of Siglent’s high-end SDS3000X HD series — a 4-channel, 12-bit oscilloscope built for engineers who need to see the detail that 8-bit scopes miss. Its 12-bit ADC (extendable to 16-bit in ERES mode) resolves small signals, low-level distortion and subtle power-rail ripple with far less quantisation noise, while a genuinely quiet front end and 0.5% DC gain accuracy keep those measurements trustworthy.
Performance keeps pace with the resolution: 4 GSa/s sampling, up to 400 Mpts of memory for long, fast captures, and a 200,000 wfm/s update rate to catch rare glitches. A 10.1" capacitive multi-touch display, USB 3.0 and Gigabit LAN make it quick to drive, and built-in Bode plot, power analysis, 4 Mpts FFT and an optional 16-channel MSO turn one instrument into a complete analysis bench — ideal for power-electronics, embedded, automotive and education work.
Analysis tools built in
12-bit high resolution
A true 12-bit ADC (up to 16-bit in ERES) reveals fine detail and small signals with far less noise than an 8-bit scope.
Bode plot & power analysis
Built-in frequency-response (Bode) and power-analysis tools for supply loop response, switching loss, harmonics and more.
4 Mpts FFT
A deep 4 Mpts FFT with magnitude and phase turns the scope into a capable spectrum tool for noise and harmonics.
10.1" multi-touch
A large 1024×600 capacitive touch display with gesture control, plus mouse, keyboard and web control over Gigabit LAN.
