Siglent STB-3 Oscilloscope Demo / Training Board

Siglent STB3 Demo Board

The Siglent STB3 is a versatile multi-signal demonstration and training board designed to showcase the advanced features of Siglent oscilloscopes. It provides a wide range of built-in analog and digital signal sources that help users learn, test, and demonstrate measurement techniques such as triggering, decoding, and waveform analysis with precision and repeatability.

Powered via USB, the STB3 generates a rich selection of test signals including sine, square, PWM, burst, AM-modulated, and even complex serial protocol waveforms such as I²C, SPI, UART, LIN, and CAN. These signals are ideal for exploring the oscilloscope’s functions — from Super Phosphor Oscilloscope (SPO) display technology to serial bus decoding, MSO (mixed-signal) operation, and pass/fail testing.

Key Features

• Multiple Built-in Signals: Includes sine, square, pulse, AM, burst, PWM, and pseudo-noise sources.

• Serial Protocol Demonstration: Built-in I²C, SPI, UART, LIN, and CAN signals for serial decoding practice.

• MSO and Pass/Fail Support: Compatible with Siglent MSO models and PASS/FAIL trigger functions (with visual LED indicator).

• Adjustable Parameters: Features controls for AM modulation depth, ERES noise level, and signal selection switches.

• USB-Powered: Convenient operation without the need for external power supplies.

Typical Applications

• Oscilloscope Demonstration & Training: Perfect for showcasing Siglent’s advanced triggering, decoding, and acquisition modes during customer demos or classroom instruction.

• Service & Calibration Labs: Provides a stable and repeatable reference source for verifying oscilloscope performance and calibration.

• Engineering Education: Ideal for universities and technical institutes to teach waveform analysis, triggering principles, and protocol decoding.

• Product Evaluation & Sales Support: A practical companion tool for demonstrating Siglent instruments at exhibitions or customer sites.

Example Demonstrations

• Waveform Types: Sine (25 MHz, 1.3 Vpp), Square (up to 10 MHz), and PWM (24.4 kHz).

• Triggering Practice: Use glitch, slope, burst, or runt signals to test advanced triggering modes.

• Serial Decoding: View decoded data frames on the oscilloscope from I²C, SPI, and CAN buses.

• MSO Mode: Combine analog and digital inputs to analyze complex embedded signals.

Included Signals
