The WaveSurfer 3000 oscilloscopes are much more than a simple oscilloscope, but are rather multi-functional instruments. For example, WaveSurfer 3000’s protocol analysis capabilities include support for the I²C, SPI, UART, and RS232 serial protocols. Once decoded, serial data streams are displayed in a color-coded overlay on top of the physical-layer signal. Users may trigger on protocol-specific information to isolate events. Up to two decodes can be done simultaneously in a combination of any protocols at any speeds. A decode table provides a quick overview of the ongoing decode and may be clicked to zoom to a specific packet.
