Deskew-Attenuation control window

From the Vertical menu, select Deskew or Attenuation.

Overview

Use the Deskew/Attenuation control window to compensate for propagation delays of different length probes and to set the input/

output ratio of any external attenuation or gain between the signal and input channels.

To use

Use the Deskew/Attenuation controls to change the settings after you set up the Vertical Setup Control Window.

Deskew (DPO70000SX series)

1. To deskew TekConnect channels, connect the channel inputs, through the cables you will use to take measurements, to the

Differential Fast Edge outputs.

2. To deskew ATI channels, connect the channel inputs, through a connector saver and the cables you will use to take

measurements, to the Differential Fast Edge outputs by way of a 1.85 mm to 2.92 mm adapter and the standard accessory

deskew attenuator and deskew cable.

CAUTION. To prevent damage to the instrument, if connecting the Differential Fast Edge outputs to an ATI channel, use a

connector saver and an attenuator.

3. Use the horizontal and vertical controls to center the fastest signal on the screen, do not use Autoset.

4. Select the slower channel.

5. Double click in the Deskew Time entry box, and use a keyboard to adjust the deskew time so the rising and falling edges

align.

6. To clear the deskew value, click the Set To 0.0s button.
