SDS2104X Plus Siglent Digital Oscilloscope Pre-Owned

Overview

The Siglent SDS2104X Plus is a 100 MHz, 4-channel digital oscilloscope from the SDS2000X Plus Series — part of Siglent's Super Phosphor Oscilloscope family. In summary, this is a 8-bit (10-bit mode)-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 SDS2104X Plus used for?

The SDS2104X Plus is used to capture, view, measure, and analyze electrical waveforms up to 100 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, Window, Runt, Interval, Dropout, Pattern and Video (HDTV). Serial (standard): I2C, SPI, UART, CAN, LIN. Optional: CAN FD, FlexRay, I2S, MIL-STD-1553B, SENT, Manchester.

Factual grounding — measurement and analysis

Data analysis functions include: Search, Navigate, Mask Test, Bode plot, Power Analysis (optional), Counter. Acquisition and measurement: Sequence up to 90,000 segments; History up to 90,000 frames; 50+ auto measurements with histogram and trend; two Math traces (2 Mpts FFT, +, −, ×, ÷, d/dt, ∫dt, √, average, ERES) with formula editor. The SDS2104X Plus delivers 2 GSa/s real-time sampling and 200 Mpts/ch, 400 Mpts total of record length — sufficient to capture long-duration events while preserving timebase resolution for zoom inspection.

Industry positioning

The SDS2000X Plus is the volume bestseller of the Siglent line — the 100 MHz/4-ch SDS2104X Plus around $1,399 is the value-tier benchmark for entry-professional oscilloscopes, undercutting the Keysight DSOX1104G by roughly $300 with comparable specs. Use the 10-bit mode and optional 50 MHz AWG to extend the bench's coverage in a single instrument.

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 SDS2104X Plus acquisition and analysis specifications are listed below. Where the SDS2000X Plus Series family shares architecture across its members, model-specific differences are concentrated in bandwidth, channel count, and (for HD-series) ADC vertical resolution.
