Serial bus decoding and triggering are important capabilities first made available in the DSOs on which MSOs are based. One or more scope analog channels can be used for this purpose on both the base DSOs and derived MSOs from all four manufacturers. Buses dealt with include I2C, CAN, SPI, UART, RS-232, FlexRay, and LIN. Not all types of buses are available from all vendors, and bundling of bus types within a single option varies by vendor.
示波器对串行总线的解码和触发的能力非常重要。最初,这些能力只有在MSO的祖宗——DSO上才能实现。不管是DSO,还是被四个厂商推多的MSO都可以有一个或者更多的模拟通道可以用作此类用途。调试的总线可以是 I2C, CAN, SPI, UART, RS-232, FlexRay, 以及 LIN。不是所有的厂商生产的MSO能够调试所有上述的总线,主要是看厂商提供那些总线的分析选项。
