Siglent SDS5038L Low Profile Digital Oscilloscope

The Siglent SDS5038L offers 8 channels with 1 GHz bandwidth and utilizes SPO technology for high-speed waveform capture (up to 160,000 wfm/s), 256-level intensity grading, and color temperature display. It features a low-jitter digital trigger system with advanced modes, including serial bus triggering, and provides tools like history recording, search and navigation, mask testing, Bode plots, power analysis, and serial decoding, along with extensive math and measurement functions. Although it lacks an integrated display and MSO capability, the SDS5038L can operate as a standalone oscilloscope when connected to an external monitor and mouse or scale to 512 channels using the SYN64 distributor for high-channel-count systems.

Complete Wide Bandgap Semiconductor Testing Solution

Siglent’s introduction of its 8-channel oscilloscopes and optically isolated probes marks a significant advancement in wide bandgap semiconductor testing. The SDS5000L series, in particular, delivers picosecond-level rise time performance, enabling precise capture of the rapid switching behavior found in silicon carbide (SiC) and gallium nitride (GaN) devices. This capability allows engineers to closely examine transient voltage and current shifts during switching events, as well as phenomena like overshoot and ringing, which are critical for refining circuit design and ensuring signal integrity.

Flexible Multi-channel High-speed Acquisition System

Multiple SDS5000L modules can be synchronized using a 64-channel distributor (SYN64) to form a high-channel-count acquisition system scalable up to 512 channels. Alternatively, an individual SDS5000L module can function as a standalone oscilloscope when connected to an external display and mouse. Remote control is supported via LAN, including web browser access. A comprehensive SCPI command set over the integrated 1000 Mbps Ethernet interface facilitates rapid data acquisition for automated test applications.

SDS5000L Low Profile Series Compared to the SDS5000X HD Benchtop Series

The Siglent SDS5000X HD and SDS5000L series oscilloscopes share core performance specifications—such as 12-bit ADC resolution, bandwidths up to 1 GHz, sample rates up to 5 GSa/s, and a maximum record length of 2.5 Gpts per channel—but differ significantly in form factor and intended use. The SDS5000X HD is a benchtop oscilloscope featuring a 12.1-inch capacitive touchscreen, optional 16 digital channels, and a user-friendly interface designed for direct interaction in lab environments. In contrast, the SDS5000L is a modular, rackmount version with no built-in display or digital channels, optimized for scalable multi-channel systems and automated test setups. It supports external display and mouse input and can be synchronized with up to 64 modules (via SYN64) for systems with up to 512 channels, making it ideal for distributed data acquisition. Both series offer identical analysis capabilities, including advanced triggering, serial decoding, and software options like power analysis and Bode plots.
