Touch the Channel or Memory Descriptor Box to open the respective dialog box,
and touch the Decode button in the bottom toolbar.
Touch a Channel, Memory, or Math trace to open a pop-up dialog that displays
a shortcut to the Decode Setup dialog box
There is a great deal of commonality in decode setup among the various serial data standards. Therefore, the
common areas are discussed next. Specifics about triggering and decoding of each protocol are discussed in
later chapters.
Serial Decode (Summary) Dialog Box
The Serial Decode dialog box shows a summary of which decoders are ON, and how they are set up. In addition,
there are shortcuts to Decode Setup and Search. A sample dialog box is shown below. This dialog box reflects an
oscilloscope that has both the I

C and SPI options.
There are four independent decoders. A user can operate up to four at a single time, though the limitation may be
on the number of channels that can be accommodated at one time. Practically speaking, if a user were decoding
signals with a clock and data line (and perhaps also a chip select or other third line), then two simultaneous
decodes would be the maximum number.
Details of the Serial Decode dialog box are described below:
Decoder # - There are four independent decoders; each can be set up a different
way for a different protocol.
