Atec Yokogawa-DL9000 Series - Manual (Page 2)

The DL9000 series allows you to measure waveforms for long periods of
time using its large-capacity memory. In addition, the memory can be
partitioned to capture only the necessary waveforms (History Memory
function). The History Memory function retains up to 2,000 waveforms in
its internal memory while constantly updating them. Now suppose an
abnormal signal occurs. You can view it even if some time has elapsed
since the occurrence, as long as
the signal is included in the
previous 2,000 waveforms. This
feature is effective in capturing
anomalies that may occasionally
occur. Furthermore, you can
compare all 2000 waveforms by
overlaying them or view them
with (different brightness levels)
depending on their frequency of
occurrence. This feature displays
waveforms similar to how they
would appear on analog
oscilloscopes.
Yokogawa’s proprietary signal-processing IC (Advanced Data Stream Engine [ADSE]) has
made the History Memory function and display functions far more advanced than those of
conventional scopes. High-speed data processing is achieved using this hardware-based
computation.
Maximum update rate in math mode:
60 frames/sec (1 MW, when adding channels)
12 frames/sec (5 MW, when adding channels)
Maximum update rate in parameter measurement mode:
60 frames/sec (1 MW, when measuring a channel’s maximum value)
16 frames/sec (5 MW, when measuring a channel’s maximum value)
History Replay Function

Capture only the desired data for long periods of time.
Make full use of the large-capacity memory to increase development efficiency
without acquiring useless data.
Fast display updates, even when processing mega-words of data
The dot density display function varies the brightness of each display pixel, depending
on how often waveforms pass through it. The DL9000 can rapidly capture waveforms at
an acquisition rate of up to 25,000 waveforms/sec. Thus the oscilloscope can show eye
patterns and perform real-time display processing even when capturing repetitive
signals. ADSE-driven high-speed signal processing enables the digital oscilloscope to
provide analog oscilloscope-like waveform displays.
You can freely change from overlaid
waveforms to any single waveform and
vice versa as the DL9000 retains
up to 2,000 frames of waveform data.
Displays waveforms like an analog oscilloscope
The History Memory function allows
you to call up a maximum of 2,000
previously acquired waveforms and
analyze the retained waveform data.

You can go back to previously-captured waveforms in History
Memory and view them one by one, just like browsing address
book entries. Furthermore, you can use the new History Replay
function to continuously play back, stop, fast-forward, and rewind
captured waveforms like a video recording.
