Data Sheet
Trigger Characteristics
Characteristic
Description
Enhanced Triggering
User-selectable; corrects the difference in timing
between the trigger path and the acquired data (not
available in FastAcq)
Acquisition Modes
Mode Description
Sample
Acquire samp
led values
Peak Detect
Captures narrow glitches as narrow as 100 ps (2 GHz
and 1 GHz models) or 200 ps (500 MHz and 350 MHz
models) at all real-time sampling rates
Averaging
From 2 to 10,000 waveforms included in average
Envelope
Min-Max envelope reflecting Peak Detect data over
multiple acquisitions
Hi Res Real-time boxcar averaging reduces random noise and
increases resolution
Roll
Scrolls sequential waveform points across the display in
a right-to-left rolling motion at sweep speeds slower than
50ms/div.Upto20MS/swithamaximumrecordlength
of 10M
FastAcq Acquisition
Mode
FastAcq optimizes the instrument for analysis of dynamic
signals and capture of infrequent events
Maximum FastAcq
Waveform Capture Rate
>250,000 wfms/s on all 4 channels simultaneously
Waveform Database Accumulate waveform database providing
three-dimensional array of amplitude, time, and counts
FastFrame™ Acquisition Acquisition memory divided into segments; maximum
trigger rate >310,000 waveforms per second. Time of
arrival recorded with each event. Frame finder tool helps
to visually identify transients
Search and M ark Events
Characteristic
Description
Automated Search and
Mark
Automatically mark events and document waveforms.
Search positive/negative slopes or both, glitches, runts,
pulse widths, transition rate, setup and hold, timeout,
windows, or find any logic or state pattern on any number
of channels. Search DDR Read or Write bursts with Opt.
DDRA. Event table summarizes all found events. All
events are time stamped in reference to trigger position.
Stop acquisitions when an event is found

take measurements on, using either screen or waveform
cursors
Waveform Histogram A waveform histogram provides an array of data
values representing the total number of hits inside
of a user-defined region of the display. A waveform
histogram is both a visual graph of the hit distribution as
well as a numeric array of values that can be measured.
