Example of shorter memory acquisitions (I2C
SDA signal capture): by skipping portions of a signal which contain no
information, many frames can be acquired in the memory.
Mega word signal capture
example (TV composite signal): 1 whole TV frame can be captured
without losing detail.
History Replay
When acquisition stops and there are more than two acquisitions in
memory, the HISTORY key is illuminated. At that time, you can use the
rotary knob to view every single acquisition in memory, one-by-one,
and look for an anomaly. The new History Replay function allows you to
play back the waveforms in memory in the same way you play back video
on a DVR.

N Single Mode |
|
When you need to
observe closely-spaced waveform events consecutively, it is
important to minimize the dead time between captures. The 'N'
single mode on the DL9000 captures up to 1,600 waveforms on each
of 4 channels with as little as 400ns of dead time between
acquisitions. In the 500ps/div range, this corresponds to an
effective acquisition rate of 2.5M waveforms/sec/channels. |

New ACCUM (accumulation) mode
When observing long-term repetitive waveform events, the ACCUM
function offers a fast repetitive signal acquisition rate of up to 25k
waveforms/sec/ch (on 4 channels simultaneously) while retaining up to
2,000 acquisitions in memory.Whether
you use 'N' single or the ACCUM function, previously acquired
waveforms are stored in memory and can be accessed using the History
Function.
Search Function
|
 |
Both Zoom search and
History search functions are available in the signalXplorer.
Zoom search locates an area of interest in
a single acquisition.
History search locates any acquisitions
in history memory that meet user-selected criteria.

Dot Density Display |
|
The intensity of
individual display pixels are varied depending on how often a
signal illuminates each pixel. Even for single shot
acquisitions, Dot Density Display provides visual information
about the S/N ratio of a signal. For repetitive signal
acquisitions, this feature offers additional insight into the
frequency of occurrence of portions of a signal over time. In
short, Dot Density Display technology offers analog
oscilloscope-like waveform representations on a digital scope. |
