Single Sweep
Pre
-
trigger segment
0% to 100% of selected sweep length
If trigger occurs before the pre
-
trigger segment is recorded, the pre
-
trigger segment is
truncated to recorded data only.
Delayed trigger
Maximum 1000 seconds after a trigger occurred. The sweep is recorded immediately after
a delayed trigger time with 100% post
-
trigger after this time point.
Sweep stretch
User selectable On/Off
When enabled, any new trigger event occurring in the post
-
trigger segment of the sweep
restarts the post
-
trigger length. If, upon the detection of a new trigger, the extended post
-
trigger does not fit within the sweep memory, sweep stretch does not happen. The maximum
sweep stretch rate is 1 sweep stretch per 2.5 ms.

Delayed trigger
Maximum 1000 seconds after a trigger occurred. The sweep is recorded immediately after
a delayed trigger time with 100% post

trigger after this time point.
Maximum number of sweeps
200 000 per recording
Maximum sweep rate
400 sweeps per second

Zero re
-
arm time, sweep rate limited to 1 sweep per 2.5 ms
Sweep stretch
User selectable On/Off
When enabled, any new trigger event occurring in the post
-
trigger segment of the sweep
restarts the post
-
trigger length. If, upon the detection of a new trigger, the extended post
-
trigger does not fit within the sweep memory, sweep stretch does not happen. The maximum
sweep stretch rate is 1 sweep stretch per 2.5 ms.
Sweep storage
Sweep storage is started immediately after the trigger for this sweep has been detected.
Sweep memory becomes available for reuse as soon as storage of the entire sweep for all
enabled channels of this card has been completed. Sweeps are stored one by one, starting
with the first recorded sweep.
Sweep storage rate
Determined by the total number of selected channels and mainframes, mainframe type,
Ethernet speed, PC storage medium and other PC parameters. For details, please refer to
the mainframe datasheet.
Exceeding sweep storage rate
Trigger event markers are stored in a recording. No sweep data is stored. New sweep data
is recorded as soon as enough internal memory is available to capture a full sweep when
a trigger occurs.
