Multiple Sweeps
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.
Maximum number of sweeps
200 000 per recording
Maximum sweep rate
400 sweeps per second
Sweep re
-
arm time
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.
Slow
-
Fast Sweep
Maximum number of Sweeps
1 per recording
Maximum slow sample rate
Fast sample rate divided by two
Maximum fast sample rate switches
20, sample rate switching always stops when sweep ends
Minimum time between sample rate switches
2.5 ms
Continuous
Continuous modes supported
Standard, Circular recording, Specified time and Stop on trigger
Standard
User starts and stops recording. Recording is stopped when the storage media is full
Circular recording
User specified recording history on storage media. All recorded data is stored on the storage
media as quickly as possible. As soon as the selected history time is reached, older recorded
data is overwritten. Recording can be stopped by the user or any system trigger.
Specified time
Recording is stopped after the time specified or when the storage media is full
Stop on trigger
Recording is stopped after any system trigger or when the storage media is full
Continuous FIFO memory
Used by enabled channels to optimize the continuous streaming rate
Maximum recording time
Until storage media filled or user selected time or unlimited when using circular recording
Maximum aggregate streaming rate per
mainframe
Determined by mainframe, Ethernet speed, PC storage medium and other PC parameters.
For details, please refer to the mainframe datasheet
Exceeding aggregate streaming rate
When a streaming rate higher than the aggregate streaming rate of the system is selected,
the continuous memory acts as a FIFO. As soon as this FIFO fills up, the recording is
suspended (no data is recorded temporarily). During this period, the internal FIFO memory
is transferred to a storage medium. When internal memory is completely empty again, the
recording is automatically resumed. User notifications are added to the recording file for
post recording identification of storage overrun.
