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.
Used by enabled channels to optimize continuous streaming rate
Until storage media filled, all recorded data will be stored including sweeps, or user selected
time
Determined by mainframe, Ethernet speed, PC storage medium and other PC parameters;
see mainframe datasheet for details
When exceeding average aggregate streaming rate, sweep storage speed is automatically
reduced to increase aggregate streaming rate, until sweep storage completely stops.
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 (Continuous and Sweep
memory) is completely empty again, the recording automatically resumes. User notifications
added to recording file for post recording identification of storage overrun.
