Read the Mnemonics Column

Various mnemonics appear in the right column of the capture display to provide a quick interpretation of the captured GPIB events. The column may also show line transitions. If the line name is followed by an up arrow (), the line transitioned from unasserted to asserted. If the line name is followed by a down arrow (), the line transitioned from asserted to unasserted. Note that if the analyzer is capturing handshake line transitions, the assertion of DAV represents a GPIB data byte or command byte. For a detailed list of the mnemonics and their meanings, refer to Capture Display Mnemonics.
