Unit Description
Pretriggered acquisitions, with user selectable pre- and post-trigger
The trigger detector flags a user-defined situation on the input signal
to start an acquisition sequence (trigger) or to arm the acquisition
(qualifier). Digital functionality applies to event channels.
Analog trigger modes
Digital trigger modes
Digital qualifier modes
Analog: individual levels
Digital
Analog: for each level; covers the selected Full Scale
Digital
Defines the trigger levels insensitivity (analog only)
Independent of storage medium used
With sweep acquisition
Continuous type acquisition
Up to 400 triggers per second, with zero re-arm time
Maximum number of triggers per recording
Triggers of all channels
Qualifiers of all event channels
Single level
Two individual levels, OR-ed
Single change of state
Arm the acquisition with a single change of state
Unit Description
Triggered acquisition to an on-board Random Access Memory (RAM)
without sample rate limitations.
Direct triggered acquisition to a PC or mainframe hard disk without file
size limitations. Triggered or untriggered.
Combination of sweeps and continuous mode: continuous type
streaming acquisition to disk with simultaneously triggered sweeps in
RAM.
A triggered acquisition in RAM which includes an acquisition phase
with a higher sample rate, located at a point of interest.
