Brief Procedures

TDS 520A, 524A, 540A, & 544A Performance Verification

Press the side-menu button Save To Selected File.

2.

Verify the file system works:

Press AUTOSET

to restore the 500 s time base and the five

cycle waveform.

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

side-menu button From File.

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 TDS assign the name TEK00000.SET to your

file.

Press the side-menu button Recall From Selected File.

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 s and the waveform shows only

two cycles just as it was when you saved the setup.

3.

Remove the test hookup:

Disconnect the standard-accessory probe from the channel input

and the probe-compensation terminals.

Remove the disk from the disk drive. Do this by pushing in the

tab at the bottom of the disk drive.
