Question	—	Siglent1104 oscilloscope channels lagging First I noticed that clock begins before chipselect gets pulled low on SPI. After eliminating potential sources I started to suspect the scope. I connected all 4 channels to function generator at different frequencies and observed 25ns gap between channel pairs. The probes were all the same 100Mhz st... (more)	—	over 2 years ago
