Acquisition Modes
Dual Combination of Multiple sweeps and Continuous; recorder type streaming to hard disk with
simultaneously triggered sweeps in on
-
board memory. Aggregate sample rate limitations
depend on Ethernet speed, PC used and data storage media used.
In Dual mode the RT
-
FDB calculators sample based results are only calculated for the
sweep sections of the recorded data. Due to the asynchronous nature of cycle based results,
all cycle based results are continuously stored and used in both the sweep as well as the
continuous sections of the recording.

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.
Multiple Sweeps
Pre
-
trigger segment
0% to 100% of selected sweep length
If trigger occurs before the pre

trigger segment is recorded, the pre

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.
Maximum number of sweeps 200 000 per recording
Maximum sweep rate 400 sweeps per second

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.
