NOTE. Symbol tables are only available when a parallel bus is selected.
Symbol files are files of alphanumeric symbol names and associated data values, and are used to map a
group value to a text string. The instrument displays the symbol in place of the numeric value. For
example, a symbol file could map an address group value to a specific bus cycle. This d
ecoding makes it
easier to recognize and locate specific numeric values on the bus.
Symbol files must follow a specificformat
(see page 154) to be compatible with the file r
eader of the
instrument.
From the Bus Setup window, select the Configure tab.
