Repetitive Signal
Increase in the time definition of a trace for a periodic signal. If this option
is valid, the signal can be averaged (see below).
Example: measurement on a microprocessor bus.
•
For time bases of less than 100 µs/div. (without mode zoom
active), the signal displayed is reconstituted on the basis of
several acquisitions. The time resolution can reach 20 µs.
•
If the signal is not repetitive, do not use this option. The
time resolution will then be ± 1 ns.
Menu present only in "Advanced" mode (see §. "Util" Menu).
Also refer to §.
"EXTENDED ACQUISITION MEMORY" option operation

The " " symbol indicates that the "Repetitive Signal" option has been
selected.
Min/Max Acquisition
Use this mode to view the extreme values of the signal acquired between
2 acquisition memory samples.
This mode:
•
detects wrong representation due to under-sampling
•
displays short-term events (Glitch,
≥
2 ns).
Whatever time base is used and the corresponding sampling speed,
short-term events (Glitch,
≥
2 ns) are displayed.
The " " symbol indicates that the "Min/Max Acquisition" mode is active.
