SDS804X HD Siglent Digital Oscilloscope New

Overview

The Siglent SDS804X HD is a 70 MHz, 4-channel digital oscilloscope from the SDS800X HD Series — part of Siglent's Super Phosphor Oscilloscope family. In summary, this is a 12-bit-resolution, 2 GSa/s-sample-rate instrument intended for general benchtop signal capture, mixed-signal debug, serial-bus decoding, and power-supply characterization.

What is the SDS804X HD used for?

The SDS804X HD is used to capture, view, measure, and analyze electrical waveforms up to 70 MHz. Typical applications: embedded system debug, power-rail characterization, motor and inverter waveform inspection, audio and sensor signal analysis, education, and serial-bus decoding for the protocols listed below.

What can it trigger on and decode?

Edge, Slope, Pulse Width, Window, Runt, Interval, Dropout, Pattern, Video (HDTV), Qualified, Nth edge, Delay, Setup/Hold. Serial: I2C, SPI, UART, CAN, LIN.

Factual grounding — measurement and analysis

Data analysis functions include: Search, Navigate, Counter, Bode plot, Power Analysis. Acquisition and measurement: Sequence up to 80,000 segments; History up to 80,000 frames; 50+ auto measurements with histogram, track, trend, gating, Math/History/Ref. 4 Math traces (2 Mpts FFT, +, −, ×, ÷, ∫, d/dt, √); hardware Mask Test. The SDS804X HD delivers 2 GSa/s real-time sampling and 100 Mpts of record length — sufficient to capture long-duration events while preserving timebase resolution for zoom inspection.

Industry positioning

The SDS800X HD is the most affordable 12-bit oscilloscope Siglent ships — $356 for the 2-ch 70 MHz SDS802X HD up to $755 for the 4-ch 200 MHz SDS824X HD. The choice for education labs, hobbyists, and bench supplementary scopes where 12-bit resolution is wanted but premium pricing isn't tolerated.

Accessories Supplied

• Oscilloscope main unit
• AC power cord (region-appropriate)
• Passive probes (one per analog channel; bandwidth-matched to the unit)
• USB cable (USB-TMC compliant)
• Quick Start guide / Programming guide reference card
• Certificate of calibration

Product Core & Specifications

The SDS804X HD acquisition and analysis specifications are listed below. Where the SDS800X HD Series family shares architecture across its members, model-specific differences are concentrated in bandwidth, channel count, and (for HD-series) ADC vertical resolution.

Unit Options

Unit Options below are multi-select — choose any combination that applies. Some options are software-licensed; others require additional hardware (e.g., logic probe). Contact your Test Architect to confirm bundle pricing.

• 16 digital channels MSO option (requires logic probe — sold separately)
• Built-in 25 MHz function / arbitrary waveform generator (built-in)
• Power Analysis software option
• Bode Plot (frequency-response measurement)

Calibration (Factory New)

All Factory New Siglent oscilloscopes ship with a factory calibration and certificate as standard. Optional upgrade calibration paths (NIST Traceable, NIST Traceable with Full Data, ISO/IEC 17025 Accredited) can be added at the time of order — please specify your required calibration tier on the order, and ValueTronics will route the unit through the appropriate calibration lab prior to shipment.
