Directory structure of the logic analyzer's file system
Both state and timing data are available, and both kinds of data are
represented as a column of values. The numeric base - hex, binary, etc. - in
these files is the same as the base that is currently set in the Listing Menu.
The lst_line.txt File The
1st line. txt
file lists the number of the
first line of the most recent data acquisition.
This file shows the number of states that occur before the trigger state, which
is always state zero (at line number 0). You can use this information to align
data from different measurements.
Time Tag and State Tag Data
If
time tags have been turned on, the
t ime_abs . txt
file contains a column of time values for the most
current state or timing measurement. Timing analyzers always have a
t ime_abs . txt
file.
If state tags have been turned on, the state_abs. txt file contains a
column of state count values for the most current state measurement.
Line Numbers The 1
ine_num. txt
file contains line numbers
corresponding to the lines of data in a state listing.
