e. Save the settings:

H Press SETUP.

H Press the main-menu button Save Current Setup; then press the

side-menu button To File.

H Turn the general purpose knob to select the file to save. Choose

 (or ). With this choice, you will save a file

starting with , then containing 5-numbers, and a  extension.

For example, the first time you run this on a blank, formatted disk or

on the Example Programs Disk, the oscilloscope will assign the

name  to your file. If you ran the procedure again, the

oscilloscope would increment the name and call the file

.

H Press the side-menu button Save To Selected File.

2. Verify the file system works:

H Press the main-menu button Recall Factory Setup and the side-menu

button OK Confirm Factory Init to restore the 500 ms time base and

the five cycle waveform.

H Press the main-menu button Recall Saved Setup; then press the

side-menu button From File.

H Turn the general purpose knob to select the file to recall. For example, if

you followed the instructions above and used a blank disk, you had the

oscilloscope assign the name TEK00000.SET to your file.

H Press the side-menu button Recall From Selected File.

H Verify that Digitizing Oscilloscope retrieved the saved setup from the

disk. Do this by noticing the horizontal SCALE for the M (main) time

base is again 200 ms and the waveform shows only two cycles just as it

was when you saved the setup.

3. Remove the test hookup:

H Disconnect the probe from the channel input and the probe-compensa-

tion terminals.

H Remove the disk from the disk drive. Do this by pushing in the tab at the

bottom of the disk drive.
