Figure 2 31: The Sampling Head Fnc's Pop Up Menu

You can specify the resolution of traces by setting the number of sample
points in a trace. This is most important if you are using a remote interface
to transfer trace data to a computer, but the effects are visible on the display.
The Horizontal Desc selector always shows the point count of the selected
trace.
Step 20: Touch Horizontal Desc in the major menu. In the pop up
menu touch either Main Record Length or Window Record Length
(both selectors assign the knobs identically).
Step 21: Turn the top Main Record Len knob one click at a time to the
left and right, and observe the difference in the main trace.
If the channel loop gain is not correctly calibrated, changing record
lengths can also change the trace appearance. See Enhanced
Accuracy in the Reference section of this manual.
