Serial Decode
• With the DSOX2EMBD license, you can decode I2C (Inter-IC) and SPI (Serial
Peripheral Interface) serial buses. See:
• “I2C Serial Decode" on page 322.
• “SPI Serial Decode" on page 331.
• With the DSOX2COMP license, you can decode many UART (Universal
Asynchronous Receiver/Transmitter) protocols including RS232
(Recommended Standard 232). See “UART/RS232 Serial Decode" on
page 339.
To determine whether these licenses are installed on your oscilloscope, see “To
display oscilloscope information" on page 261.
To order serial decode licenses, go to www.keysight.com and search for the
product number (for example, DSOX2AUTO) or contact your local Keysight
Technologies representative (see www.keysight.com/find/contactus).
Lister
Lister is a powerful tool for investigating protocol failures. You can use Lister to
view large amounts of packet level serial data in a tabular format, including time
tags and specific decoded values. After pressing the [Single] key, you can press the
Scroll Lister softkey and then rotate the Entry knob to select an event and press the
Zoom 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 ) on
which the serial bus signals are being decoded.
