Siglent SDS5108L 8-Channel Digital Oscilloscope

Overview

The Siglent SDS5108L is a modular, low-profile 8-channel oscilloscope designed for rackmount systems and distributed data acquisition applications. With 1 GHz bandwidth, 5 GSa/s sampling rate, and 12-bit ADC resolution, it delivers high-speed waveform capture without a built-in display. The SDS5108L operates as a standalone oscilloscope when connected to an external monitor and mouse, or scales to 512 channels using the SYN64 distributor for multi-module systems.

Key Features

• 8 analog channels with 1 GHz bandwidth and 5 GSa/s sampling rate
• 12-bit ADC for high-resolution measurements up to 2.5 Gpts memory depth
• Waveform capture rate up to 160,000 wfm/s in normal mode and 650,000 wfm/s in sequence mode
• Low noise floor of 140 µVrms at 1 GHz bandwidth (typical)
• 256-level intensity grading and color temperature display modes
• Intelligent triggering with edge, slope, pulse, window, pattern, and video modes
• Serial bus decoding for I2C, SPI, UART, CAN, LIN, and optional protocols
• History recording of up to 170,000 waveform frames
• 60+ automatic measurements with histogram and statistical analysis
• 8 math traces supporting FFT, filtering, and custom formulas
• Segmented acquisition mode for capturing multiple triggered events with minimal dead time
