Basic Applications
6. Using the center vertical graticule line as a reference point, set the ref
erence delay to align the B Sweep display of the first point of interest to
be measured to that reference point with the K- OR DELAY control. Set
the time delay to align the B Sweep display of the second point of
interest to the reference point using the -H control. The time difference
between the two B Sweep delays is displayed at the top of the screen.
Once the measurement points are identified, the A Intensified Sweep
traces may be removed from the display for ease in viewing the B Sweep
traces by switching to B Delayed Horizontal MODE. In B Horizontal MODE,
exact placement of the two delays may be obtained by positioning one
trace over the other and then aligning the measurement point using the -»|
control. Additional resolution may be obtained by advancing the B SEC/DIV
switch setting to further expand the B Sweep traces.
