Saving a File

Loading a file

1.Reset the analyzer by pressing Preset, Factory Preset (if present).

2.To access the Load menu, press File, Load.

3.Select the type of file you want to load (setup, state, trace, limits, or corrections). In this example you are loading a trace file; press Type, Trace.

NOTE

Not all file types can be loaded back into the analyzer. For example, Screen

 

files and CSV (comma separated value) files cannot be loaded. CSV and

 

Screen files are designed for use with a PC.

 

 

4.Select the directory where your file is located. In this example, select the C:\START\ directory. (Use the front-panel step keys, knob, Dir Up, and/or Dir Select keys to locate the directory.)

5.Select the file you want to load into the analyzer by moving the cursor with the front-panel knob to highlight the file name. In this example the file is TEST1.TRC. Select the trace into which you wish to load the file. In this example, load it into Trace 2. (Destination, Trace 2).

6.Press Load Now to load the specified file. Your display should look similar to Figure 4-6. The status bar reads: C:\START\TEST1.TRC file loaded.
