Direct storage to PC or mainframe controlled hard disk without file size limitations; triggered
or un-triggered; for long duration recorder type applications. Aggregate sample rate
limitations depending on Ethernet speed, PC used and data storage media used.
Combination of Multiple sweeps and Continuous; recorder type streaming to hard disk with
simultaneously triggered sweeps in on-board memory. Aggregate sample rate limitations
depending on Ethernet speed, PC used and data storage media used.

0 % to 100 % of selected sweep length
If trigger occurs before pre-trigger segment is recorded, pre-trigger segment is truncated to
recorded data only
Maximum 1000 seconds after a trigger occurred. Sweep is recorded immediately after
delayed trigger time with 100 % post-trigger after this time point
User selectable On/Off
When enabled, any new trigger event occurring in the post-trigger segment of the sweep
will restart the post-trigger length. If upon the detection of a new trigger, the extended
post-trigger doesn't fit within the sweep memory, sweep stretch will not happen. Maximum
sweep stretch rate 1 sweep stretch per 2.5 ms
0 % to 100 % of selected sweep length
If trigger occurs before pre-trigger segment is recorded, pre-trigger segment is truncated to
recorded data only
Maximum 1000 seconds after a trigger occurred. Sweep is recorded immediately after
delayed trigger time with 100 % post-trigger after this time point
200 000 per recording
400 sweeps per second
Zero re-arm time, sweep rate limited to 1 sweep per 2.5 ms
User selectable On/Off
When enabled, any new trigger event occurring in the post-trigger segment of the sweep
will restart the post-trigger length. If upon the detection of a new trigger, the extended
post-trigger doesn't fit within the sweep memory, sweep stretch will not happen. Maximum
sweep stretch rate 1 sweep stretch per 2.5 ms.
Sweep storage starts immediately after the trigger for this sweep is 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 will be stored one by one starting with
the first recorded sweep.
Determined by total number of selected channels and mainframes, mainframe type,
Ethernet speed, PC storage medium and other PC parameters; see mainframe datasheet
