Figure 3–4: Localizing a measurement using cursor gating
Before starting the measurement, specify the portion of the waveform to be
measured as follows:
1. Press Cursor Gating (main)
➞
On/Off (side). Select ON. See Figure 3–4.
When cursor gating is On, the cursors are turned on and the read channel is
selected.
2. Place the cursors at the beginning and end of the waveform segment of
interest.
When you perform the measurement, only the data between the cursors will be
measured.
When cursor gating is Off, the application measures the full record length.
NOTE . The cursor gating function in this menu applies to the measurements in
the Disk Drive Measurement Application only. It does not apply to measure-
ments in the main Measure menu of the oscilloscope.
