Acquisition Modes
Single sweep
Triggered acquisition to on
-
board memory without sample rate limitations; for single
transients or intermittent phenomena. No aggregate sample rate limitations.
Multiple sweeps
Triggered acquisition to on
-
board memory without sample rate limitations; for repetitive
transients or intermittent phenomena. No aggregate sample rate limitations.
Slow
-
Fast Sweep
Identical to single sweep acquisition with additional support for fast sample rate switches
during the post
-
trigger segment of the slow rate single sweep settings. No aggregate sample
rate limitations. Slow
-
Fast Sweep is not supported by the RT
-
FDB calculators.
Continuous
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 depend on Ethernet speed, PC used and data storage media used.
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.
