Trigger event markers are stored in recording, no sweep data stored. New sweep data
recorded as soon as enough internal memory is available to capture a full sweep when
trigger occurs.

rate
400 sample rate switches per second, 200 000 switches maximum, switching stops when
sweep ends
Standard, Circular recording, Specified time and Stop on trigger
Standard User starts and stops recording. Automatic recording stop on storage media full.
Circular recording User specified recording history on storage media. All recorded data stores as quickly as
possible on selected storage media. As soon as selected history time is reached older
recorded data is overwritten. Recording can be stopped by user, or any system trigger.
Specified time Automatic recording stop after user specified time or on storage media full
Stop on trigger Automatic recording stop after any system trigger or on storage media full
Used by enabled channels to optimize continuous streaming rate
Until storage media filled, or user selected time or unlimited using circular recording
Determined by mainframe, Ethernet speed, PC storage medium and other PC parameters;
see mainframe datasheet for details
When using a streaming rate selected higher than the aggregate streaming rate of the
system, the continuous memory will act as a FIFO. As soon as this FIFO fills up, the
recording suspends (temporarily no data is recorded). During this period, the internal FIFO
memory is transferred to storage medium. When internal memory is completely empty
again, the recording automatically resumes. User notifications added to recording file for
post recording identification of storage overrun.
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 recording
400 triggers 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
sweepstretch rate 1 sweep stretch per 2.5 ms
In dual mode the storage of the continuous data is prioritized above the storage of the sweep
data. If enough storage rate is available, the 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 continuous sample rate, total number of channels and mainframes,
mainframe type, Ethernet speed, PC storage medium and other PC parameters. See
mainframe datasheet for details.
Continuous recorded data not stopped, trigger event markers are stored in recording, no
new sweep data stored. New sweep recorded as soon as enough internal memory is
available to capture a full sweep when trigger occurs.
