+PEAK voltage measurement and tracking
Only a choice of 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 gnd in that order.
Also the TRACK TRIG LVL and TRACK gnd cursors
may only be displayed on the Trigger SOURCE sig-
to either CH 1 or CH 2 input signal without regard as

4. The width of the gated zone is controlled by the ~!
OR A control. Adjust the width to define the gated mea-
surement zone.

+PEAK voltage that occurs within the zone.
CURSOR MEASUREMENTS
Time and voltage measurements may be made using
cursors
to
identify
the
measurement
points
on
the
waveform. Time measurement cursors may be used on
any of the
input waveforms only
in
the
A
Horizontal
MODE. The units of the time cursors may be selected to
provide some automatic calculations
for the user. The
units of the i- SEC ~l cursors are time (s, ms, us, and ns),
the I+ 1/SEC -1 cursors have units of frequency (Hz, kHz,
and MHz), and the I- PHASE -! cursor units are in degrees
and scaled to a 360 degree reference set by the user. The
time cursors that appear in the CURSORS measurement
mode and the time cursors that appear in the ATIME
measurement mode in the A Horizontal MODE are exactly
Voltage cursors are attached to a measurement chan-
nel (either CH 1 or CH 2) to obtain their scaling. Voltage
measurements using cursors may be done on the CH 3,
the CH 4, or the ADD waveform by setting the VOLTS/DIV
setting of the selected measurement channel to the same
scale factor as the signal to be measured. However, the
