Decode Setup Dialog - LeCroy WavePro 7 Zi series Operator's Manual

WavePro 7Zi
Decode ON Checkbox - If checked, it means the decoder is turned ON and will
decode, assuming the protocol is correctly set up in the Decode Setup dialog box.
Protocol - This pop-up dialog allows selection of a specific serial protocol. In some
cases where the protocol is not completely standardized, or where there are higher-
level definitions of the protocol, multiple selections may be provided. For example,
SPI has variants with no chip select. Examples are Simplified SPI (SSPI), and
Simple Synchronous Serial I/O Port, (SIOP). Each of these has a selection in this
pop-up dialog.
Data and Clock Selection - This pop-up dialog allows you to select a channel or
other source for decoding. Some protocols may require a third selection (for
instance, SPI also requires a Chip or Slave Selection).
Decode Setup Shortcut Button - This provides quick access to the second tab
(Decode Setup) where there are quick buttons for Search, and Table (Configure
Table and Export Table).
Search - Push this button to open a Zoom (Zx trace) that has as its source the
corresponding Channel (Cx trace). In addition, the right-hand dialog in the Zoom
trace has Search options specific to the serial protocol that the Source is assigned
to.
The Decode Setup dialog box is where the details of a specific protocol decode are entered. It appears as follows:
This is a single tab with an indicator on the left side that describes which of the four decoders the setup
information pertains to. The left-hand side of this dialog box is described as follows (the right side is described in
the protocol-specific sections):
1. Decoder # Buttons - This describes which of the four decoders to which the currently entered information
pertains.
2. View Decode Checkbox - Check this box to turn on decoding. Decoding ON will provide a highlight of
each message frame, with color-coded highlighting and decoding of the various portions of the protocol
message. Note that for very long acquisitions with hundreds or thousands of messages, decoding of the
entire acquisition will take longer.
