7. Touch the Graph button, then touch inside the Graph with field to select a graph mode. The
Graph modes are as follows:

Resampling To Deskew

Deskew whenever you need to compensate for different lengths of cables, probes, or anything
else that might cause timing mismatches between signals. Resample a signal on one channel
and adjust it in time relative to a signal on another channel.

Resampling

1. In the menu bar, touch Math, then Math Setup... in the drop-down menu.
2. Touch a math function trace tab F1 through Fx The number of math traces available depends
on the software options loaded on your scope. See Specifications..
3. Touch the single function button.
4. Touch inside the Source1 field and select a source: channel, math trace, memory location.
5. Touch inside the Operator1 field and select Deskew from the Functions category.
6. In the dialog on the right, touch the Deskew tab.
7. Touch inside the Delay by data entry field and type in a time value, using the pop-up keypad.

Rescaling and Assigning Units

This feature allows you to apply a multiplication factor (a) and additive constant (b) to your
waveform: aX + b. You can do it in the unit of your choice, depending on the type of application.
Allowable unit abbreviations are as follows:
180
Histogram of the values of a parameter
Track of the values of a parameter
Trend of the values of a parameter
(blank) no units
A Ampere
C Coulomb
CYCLE cycles
DB Decibel
DBC Decibel referred to carrier
DBM Decibel Milliwatt
DBV Decibel Volts
DBUZ Decibel Microamp
DEC Decade
DIV Divisions
