Characteristic
Trend Track
Ensures No Lost
Measurement Data
No. Since data can be accumulated over many
acquisitions, and since the oscilloscope takes
time to calculate measurement values and to
display data before the trigger is re-armed, data
can be missed.
Yes. Maximum time period
that can be captured is
limited by acquisition
memory and sampling rate.
In general, Track will be the tool to use if you want to capture a continuous stream of data that is spaced closely
together. Trend can be used if your data is spaced widely apart and longer than the “dead-time” of the
oscilloscope between acquisitions.
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.
Deskewing
1. Touch Math Math Setup on the menu bar.
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: a X + b . You
can do it in the unit of your choice, depending on the type of application.
