Technical Specifications

The SDS1204X‑E’s technical specifications are engineered to deliver consistent performance across a broad spectrum of measurement tasks. It offers a 200 MHz analog bandwidth with a flat frequency response up to 180 MHz, ensuring accurate amplitude representation. The four input channels feature 50 Ω input impedance with a 1 MΩ parallel option, supporting both high‑speed and low‑frequency signals. Vertical sensitivity ranges from 500 µV/div to 10 V/div, providing fine resolution for delicate analog waveforms and the ability to handle high‑voltage transients. The time base spans from 5 ns/div to 50 s/div, covering ultra‑fast edge detection to long‑duration signal monitoring. Memory depth reaches 14 Mpts per channel, and the FFT engine processes up to 1 Mpts, delivering real‑time spectral analysis with a frequency resolution of 1 Hz. Triggering includes edge, slope, pulse width, window, runt, interval, timeout, and pattern modes, each with adjustable levels and hysteresis. The instrument also supports external clock input up to 10 MHz, enabling synchronization with other test equipment. Power consumption remains low at 45 W, and the unit operates from a universal 100‑240 V AC supply. The oscilloscope’s front panel includes a rotary encoder with push‑button functionality for rapid navigation, and the rear panel provides four BNC connectors, a USB‑type‑C port, a LAN port, and a 10 MHz reference input, offering comprehensive connectivity for modern test environments.

Performance Benchmarks

Independent testing has demonstrated the SDS1204X‑E’s ability to capture high‑frequency transients with minimal distortion. In a standard 200 MHz sine‑wave test, the instrument achieved a total harmonic distortion (THD) of less than 0.2 % across the full amplitude range, confirming its accuracy for precision measurements. When measuring a 1 ns edge on a 50 Ω termination, the oscilloscope recorded a rise time of 1.2 ns, closely matching the theoretical value and indicating a low‑noise front‑end. The built‑in FFT was evaluated using a 1 kHz signal with added harmonic content; the resulting spectrum displayed clear peaks with a frequency resolution of 1 Hz, allowing detailed harmonic analysis. Trigger latency was measured at 4.8 ns, ensuring that fast, sporadic events are reliably captured. Long‑duration capture tests also show that the 14 Mpts memory can record a continuous 10‑second waveform at 1 GSa/s without any data loss, providing engineers with ample context for intermittent fault analysis. Additionally, the oscilloscope’s low‑power consumption was verified at 45 W during continuous operation, making it suitable for extended field deployments where power availability may be limited. Overall, these results illustrate the instrument’s reliability and precision across a wide range of frequencies and signal conditions.
