HDO6000 High Definition Oscilloscope
When using third-party probes, the Probe Attenuation and Deskew values may be entered manually on the
Channel dialog.
Probe Information on Probe Dialog
This additional tab contains specific information on the connected probe. Default values for the probes
coupling and attenuation are automatically downloaded from the probe, and these settings along with
other attributes are shown on the dialog. Other controls may be available depending on the probe model or
input device type.

Deskew Channels
The signal input channels are deskewed at the factory prior to shipment and should not require any
further action.
Follow this generic deskew procedure to compensate for propagation delays due to different lengths of
cables, probes, or anything else that might cause timing mismatches between signals.
1. Connect all probes to the desired channels, then probe a common signal with each probe.
2. Turn on two channels, one of which will be the reference channel for the entire deskew procedure.
3. Set an Edge trigger on the reference channel.
4. Switch to Display > Single Grid so both traces appear on the same grid.
5. Turn the Front Panel Horizontal knob to adjust Time/div so that you can clearly see the edges of each
trace.
6. Touch the channel descriptor box for the second channel twice to open the setup dialog.
7. Touch the Deskew field to activate it.
8. Turn the Front Panel Adjust knob until the trace aligns with the reference waveform.
9. Repeat Steps 2 through 8 for each input, using the same channel as the reference and same trigger
each time.
