Super-Long Memory and Quick Zoom for Finding the Target Signal in Long-Period Phenomena
|

32 MW long memory and Dual Zoom
|
|
|
Super-long memory enables you to capture high-speed phenomena for the desired period of time, while providing fast sampling speeds required for reliable measurements. Up to 32 MW of data (with the DL1640L) can be acquired even when all four channels are used. As shown in the picture, during the evaluation of a switching power supply, for example, this capacity lets you capture three different signals (switching element voltage, current, and primary-side surge current) from the time the power is turned on until switching starts and stabilization occurs. Super-long memory also lets you maintain high-speed sampling, so individual pulses can be accurately displayed on the screen.
The zoom function rapidly displays the target phenomenon contained in large amounts of waveform data. The Dual Zoom function enables you to zoom in on two portions of the waveform at one time.

All-Points Display and Fast Screen Updating for Capturing Hidden Abnormal Phenomena
|
All-points display shows all of the data stored in long memory. This display mode shows phenomena that may be missed in a compressed waveform display. With Yokogawa's proprietary Data Stream Engine II, screen updating speed does not slow down even during zoom display or automatic parameter measurement. With fast screen updating, display changes corresponding to modified settings take place instantaneously, so instrument control is responsive.

Smart Search Function for Effective Access to Data You Need
|
"I want to find the serial data with a particular serial pattern", "I need to search for surge pulses of less than 30 ns", "I want to only extract waveforms that occasionally overshoot by an excessive amount".......As data volume increases, it becomes more important to be able to search for target phenomena efficiently. The Smart Search function automatically detects serial patterns, pulse widths, rising edges, falling edges, and other phenomena in the captured waveform data. These phenomena are then displayed in the zoom screen. Smart Search will significantly improve the efficiency of your development and evaluation work.

Data Stream Engine II with internal digital filters
|
|
|
One important role for oscilloscopes is measuring noise in the waveforms. Sometimes, however, this noise prevents you from observing the target signals. The real-time digital filtering lets you easily apply a low pass filter while capturing data, so that waveforms hidden in noise can be clearly displayed.
Filters can be set separately on each channel. In combination with an analog filter, cutoff frequencies ranging from 20 MHz to 10 kHz can be set.

Without filtering (200 MHz BW)
Waveform mixed with noise |
Filter cutoff frequency: 10 kHz
Waveform without high-frequency noise |
|
|
When the real-time digital filtering is used in high-resolution mode, data resolution increases to up to 13 bits, and signals can be reproduced even more clearly on the screen.
|
|
This helps to evaluate ECU signals containing ignition noise and inverter output superimposed with high-speed switching noise.
