Complete Wide Bandgap Semiconductor Testing Solution

The addition of 6- and 8-channel oscilloscopes along with optical isolation probes completes the toolkit for testing wide bandgap semiconductors. These oscilloscopes feature picosecond-level rise times, allowing precise capture of the rapid waveforms produced by SiC and GaN devices. This capability enables detailed analysis of voltage and current transients as well as switching behavior. By examining signal characteristics such as shape, overshoot, and ringing, engineers can assess signal integrity and refine circuit designs for optimal performance.

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.
