Auto-measure Accesses the Auto-measure menu. The auto measure function performs
a measure at marker on all signals that meet the criteria (above the
margin or peak excursion) followed by an add to the list of all the
signals on the screen.

Start Starts the Auto-measure process. Pressing this softkey
starts a series of routines which are designed to detect
the presence of signals and perform zero span
measurements on each one. As the measurement is
made, each signal is swept once (on the screen) to help
you keep track of the progress of the measurement. The
sweep that is shown is the last sweep before zooming to
zero span. If the signal list is turned On, you can see
each signal as it is added to the end of the signal list.

Sigs > Margin
When On is selected, only the signals above the lowest
limit line margin on the screen are measured. If Off is
selected or no margin is on the screen then all the
signals on the screen that meet peak excursion are
measured. Default is Off.

Peak
On Off
Allows you to turn peak measurements On and Off.
When Peak is On, you can change the measurement
dwell time. If this detector is On, the Measure at
Marker and Auto-measure functions make a peak
detector measurement for the specified dwell time.
Default is On with a 200 ms dwell time.

Quasi Peak
On Off
Allows you to turn quasi-peak measurements On and
Off. When Quasi Peak is On, you can change the
measurement dwell time. If this detector is On, the
Measure at Marker and Auto-measure functions make
a quasi-peak detector measurement for the specified
dwell time. Default is On with a 200 ms dwell time.
