Basic Applications
1. Select GATED +PEAK measurement mode. The menu will be removed
(If configured to do so), and any enabled tracking cursors will be dis-
played. If none are enabled In page 2 of the CURSOR VOLTS menu,
none will be displayed.
NOTE
Only two of the possible three available selections may be
displayed (on a priority basis). TRACK MEASMT has the
highest priority, followed by TRACK TRIG LVL and
TRACK sh in that order. Also the TRACK TRIG LVL cursors
may only be displayed on the Trigger SOURCE signal. The
TRACK MEASMT cursor may be directed to either CH 1 or
CH 2 input signal without regard to the trigger signal
SOURCE.
2. Adjust the B INTEN and A INTEN controls to provide a good viewing
contrast of the Intensified zone that appears on the A Sweep trace.
NOTE
If the zone does not appear, it may be positioned out of the
viewing area (but not past the end of the A Sweep trace).
Turn the \— OR DELAY control counterclockwise to move
the gate zone closer to the beginning of sweep.
3. Use the + OR DELAY control to position the intensified zone to the area
of interest on the waveform to be tracked. (See Figure 5-2.)
4. The width of the gated zone Is controlled by the -4 control. Adjust the
width to define the gated measurement zone.
5. The voltage value that appears in the readout Is the +PEAK voltage that
occurs within the zone.
