===Protocol analyzers===
{{Main articles|Logic analyzer}}
[[Logic analyzers]] are tools which collect, [[timestamp]], analyze, decode, store, and view the high-speed waveforms, to help [[Debugging|debug]] and develop. Most logic analyzers have the capability to decode SPI bus signals into high-level protocol data with human-readable labels.

==== Oscilloscopes ====
SPI [[waveforms]] can be seen on [[Analog signal|analog]] channels (and/or via [[Digital signal|digital]] channels in [[Oscilloscope#Mixed-signal oscilloscope|mixed-signal oscilloscopes]]).<ref>{{cite web |title=N5391B I²C and SPI Protocol Triggering and Decode for Infiniium scopes |url=https://www.keysight.com/en/pd-1646694-pn-N5391B/ic-and-spi-protocol-triggering-and-decode?cc=US&lc=eng}}</ref> Most [[oscilloscope]] vendors offer optional support for SPI protocol analysis (both 2-, [[Serial Peripheral Interface#Three-wire|3-]], and 4-wire SPI) with triggering.
