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 320.
• "SPI Serial Decode" on page 329.
• 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 259.
To order serial decode licenses, go to "www.agilent.com" and search for the
product number (for example, DSOX2AUTO) or contact your local Agilent
Technologies representative (see
"www.agilent.com/find/contactus)."
