2. Confirm all four channels are within limits for channel delay:
a. Set up the generator: Set the generator frequency to 250 MHz and the
amplitude for six to eight divisions in CH 1.
Hint: As you are adjusting the generator amplitude, push SET LEVEL
TO 50% frequently to speed up the updating of the waveform amplitude
on screen.
b. The horizontal SCALE should already be set to 500 ps. On the
TDS 580D, 784D, 794D, and all TDS 600C, now set it to 200 ps. On the
TDS 520D, 540D, 714L, 724D, and 754D, push the front-panel ZOOM
button, press the side-menu On button, set the horizontal SCALE to
250 ps, and be sure the vertical scale factor is kept at 1.0X and the
horizontal scale factor is 2.0X for the remainder of this check.
c. Save a CH 2 waveform: Press CH 2. Press save/recall WAVEFORM.
Now, press the main-menu button Save Wfm; then press the side-menu
button
To Ref 2.
d. Save CH 3 (AX1 on some TDS models) waveform:
H Move the coupler from CH 2 to CH 3 (AUX1 on some TDS
models), so that CH 1 and CH 3 are driven. Press WAVEFORM
OFF. Press CH 3. Then press the side-menu button To Ref 3.
e. Display all test signals:
H Press WAVEFORM OFF to remove CH 3 (AX1 on some TDS
models) from the display.
