SDS7404A H12 Siglent Digital Oscilloscope New

Overview

The Siglent SDS7404A H12 is a 4 GHz, 4-channel digital oscilloscope from the SDS7000A Series — part of Siglent's Super Phosphor Oscilloscope family. In summary, this is a 12-bit-resolution, 20 GSa/s-sample-rate instrument intended for general benchtop signal capture, mixed-signal debug, serial-bus decoding, and power-supply characterization.

What is the SDS7404A H12 used for?

The SDS7404A H12 is used to capture, view, measure, and analyze electrical waveforms up to 4 GHz. 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, Window, Runt, Interval, Dropout, Pattern, Qualified, Nth edge, Setup/hold, Delay, Video (HDTV), Zone Trigger. Serial: I2C, SPI, UART, CAN, LIN, CAN FD, CAN XL, FlexRay, I2S, MIL-STD-1553B, SENT, Manchester, ARINC429, USB 2.0.

Factual grounding — measurement and analysis

Data analysis functions include: Search, Navigate, SignalScan, Digital Voltmeter, Counter, Waveform Histogram, Bode plot, Power Analysis, Eye/Jitter Analysis, Compliance Test (USB 2.0, 100Base-TX, 1000Base-T, 100Base-T1, 1000Base-T1, MIPI-DPHY). Acquisition and measurement: Up to 124,000-segment Sequence acquisition; History up to 124,000 frames; 60+ automatic measurements with histogram, track, trend, gating, and Math/History/Memory traces; 4 Math traces (32 Mpts FFT, Filter, +, −, ×, ÷, ∫, d/dt, √, etc.) with formula editor; Hi-speed hardware Average, ERES, and Mask Test with Mask Editor. The SDS7404A H12 delivers 20 GSa/s real-time sampling and 1 Gpts/ch of record length — sufficient to capture long-duration events while preserving timebase resolution for zoom inspection.

Industry positioning

The SDS7000A is the flagship of Siglent's 12-bit Super Phosphor line — the only Siglent platform that competes against premium-brand 8 GHz scopes on bandwidth and capture rate. Best paired with the SAP5000D 5 GHz differential active probe.

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 SDS7404A H12 acquisition and analysis specifications are listed below. Where the SDS7000A Series family shares architecture across its members, model-specific differences are concentrated in bandwidth, channel count, and (for HD-series) ADC vertical resolution.
