7 Serial Decode
• With the DSOX3EMBD license, you can decode I2C (Inter-IC) and SPI
(Serial Peripheral Interface) serial buses. See:
• "I2C Serial Decode" on page 366.
• "SPI Serial Decode" on page 375.
• With the DSOX3AUDIO license, you can decode I2S (Inter- IC Sound or
Integrated Interchip Sound) serial buses. See "I2S Serial Decode" on
page 387.
• With the DSOX3COMP license, you can decode many UART (Universal
Asynchronous Receiver/Transmitter) protocols including RS232
(Recommended Standard 232). See "UART/RS232 Serial Decode" on
page 411.
• With the DSOX3AERO license, you can decode MIL- STD-1553 and
ARINC 429 serial buses. See:
• "MIL- STD-1553 Serial Decode" on page 394.
• "ARINC 429 Serial Decode" on page 401.
To determine whether these licenses are installed on your oscilloscope, see
"To display oscilloscope information" on page 296.
To order serial decode licenses, go to "www.agilent.com" and search for the
product number (for example, DSOX3AUTO) or contact your local Agilent
Technologies representative (see "www.agilent.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
or Serial 2) on which the serial bus signals are being decoded. (If you
