Trace File
All graphic systems
File name of the trace files to be loaded for parameter fields Y-Source = File: Trace A
and/or File: Trace B.
If a file cannot be loaded because it does not match the current graphic system or is
defective, "not loaded" is displayed.
If a trace file that contains Min/Max scans is loaded, "Show Min Max" is enabled auto-
matically so that these scans are displayed in the graphic.
If files with different x-axes are loaded one after the other, the last file always deter-
mines the x-axis. If a sweep with a different x-axis is then loaded, it will determine the
x-axis.
For file format, see Chapter 5.6.7, "Random" , on page 249.
