• Probe Attenuation Factor— This is set automatically if the oscilloscope can
identify the connected probe. See “AutoProbe Interface” on page 72 and
“Manually Setting the Probe Attenuation Factor” on page 80.
• Skew — When measuring time intervals in the ns range, small differences in cable
length can affect the measurement. Use Skew to remove cable-delay errors
between any two channels.
Probe the same point with both probes, then press Skew and turn the Entry knob to
enter the amount of skew between channels. Each analog channel can be adjusted
±100 ns in 10 ps increments for a total of 200 ns difference.
The skew setting is not affected by pressing [Save/Recall]&Default Setup or by
pressing [Auto Scale].
• Calibrate Probe — See “Calibrating Probes” on page 78.
