Basic Applications
6. For a peak-to-peak voltage measurement, slightly reposition the cur­
sors as necessary to precisely align them with the peaks of the
waveform. The |<- OR DELAY control positions both cursors together
(keeping the original difference between cursors), and the -M control
positions the Independent cursor. Read the measurement value dis­
played in the top line of the readout.
7. To make voltage difference measurements between any other locations
on the waveform, move the K- cursor to the more-negative point of
interest, then position the independent -»| cursor to the more positive
point on the waveform. Read the voltage difference.
Time Measurement Cursors
Time measurement cursors may be used on any of the input waveforms
only in the A Horizontal MODE. (Time measurements are also available in
ALT and B Horizontal MODE;
see “ Time Delay Measurement" in this
section.)
T im e D iffe ren c e
Use the following procedure steps as a guideline in making time difference
measurements using the TIME cursors. As with the voltage cursors, the
|«- OR DELAY control positions both cursors together, and the -H control
positions the independent (delta-time) cursor.
1. Apply the signal to the input connector(s).
NOTE
Make sure that the signal used as the trigger source is con­
nected to the lowest numbered channel that will be turned
on.
