See:• “I2C Serial Decode" on page 322.• “SPI Serial Decode" on page 331.• With the DSOX2COMP license, you can decode many UART (UniversalAsynchronous Receiver/Transmitter) protocols including RS232(Recommended Standard 232). See “UART/RS232 Serial Decode" onpage 339.To determine whether these licenses are installed on your oscilloscope, see “Todisplay oscilloscope information" on page 261.To order serial decode licenses, go to www.keysight.com and search for theproduct number (for example, DSOX2AUTO) or contact your local KeysightTechnologies representative (see www.keysight.com/find/contactus).ListerLister is a powerful tool for investigating protocol failures. You can use Lister toview large amounts of packet level serial data in a tabular format, including timetags and specific decoded values. After pressing the [Single] key, you can press theScroll Lister softkey and then rotate the Entry knob to select an event and press theZoom to Selection softkey to jump to the event.To use the Lister:1 Set up trigger and decode on the serial data signals to be analyzed.2 Press [Serial] > Lister.3 Press Display; then, turn the Entry knob to select the serial slot (Serial 1) onwhich the serial bus signals are being decoded.
