Acquisition of signal and refreshing of the screen on the first trigger occurring

(or via the time base menu).
In single-sweep mode, if the time base is over 50 ms/div, new samples are
displayed as soon as they are acquired and ROLL mode is activated as soon as
the acquisition memory is full (scrolling of the trace from the right to the left of the
screen).
The ROLL mode is not possible if the trigger on automatic measurement
threshold is active.
•
The " " symbol indicates the selected trigger mode.
•
The selected trigger mode is indicated in the status area
(Trig'd, Auto, Single).
•
The acquisition status is indicated in the status area: PRETRIG, RUN,
STOP, POSTRIG, READY, …
This selection can also be called up by double-pointing with the stylus on the
time base display area.
Triggering on
thresholds
Triggering on thresholds consists of:
1. acquisition implemented according to the conditions defined in the various
menus,
2. analysing the trigger signal after classic acquisition,
3. searching for a condition on an automatic measurement,
4. if this condition is met, displaying the validated signals.
If "measurement on thresholds" is activated, the status zone at the foot of the
screen indicates it.
When threshold values are input, the instrument displays an error message if the
measurement of a threshold value is impossible.
Save / Restart
If this option is activated, all the traces acquired are saved to .TRC and .MAC
files after each acquisition.
As a result, you can save several rare events to the file system and analyse
them later.
The channels are saved in files, the name of which is determined according to
the date and time they are saved.
They can be saved on an FTP server or in the local file system if the FTP server
parameters have been configured (menu: "UTIL" "Config I/O Ports"
"Network")
