Large capacity memory up to 500 Mpoints
Long memory is necessary to maintain high speed sample rates during long-term measurements.

[Basic Formula]
Measuring time = Memory length/Sample rate
If 500 Mpoints (Memory expansion option /M2) is installed, up to 0.2 seconds waveform can be captured even at 2.5 GS/s sample rate while taking 2-ch Single Mode measurements.

• History

Determining cause and effect relationships is a daily task for design and validation phases of mechatronics projects. To provide the necessary extensive data sets, Yokogawa oscilloscopes take advantage of the large internal storage to retain data from previous capture events. Because the actual waveform data is stored, these events are available for browsing, visualization, measurement and searching using the History feature. Up to 100,000 previous captures are available depending on the record size and sampling rate.

• Search box

When visualizing all captures in history memory, it’s easy to see an outlier waveform. Using the search box and the touchscreen, it’s easy to draw search conditions directly on the waveform and isolate the occurrence.

The search box (white box) is used to isolate signals falling within its boundaries, making it easier to deal with thousands of data sets simultaneously. Here, two glitches are highlighted for Search.

• Statistics

Single measurements are very informative, but many projects require statistical measurements across a large data set. The DLM3000 can also perform measurements across the entire history memory, providing statistical analysis of maximum, minimum, mean, and standard deviation. For inspection of unusual measurements, the List function displays all values, indicating maxima and minima with arrow symbols, and tapping or selecting any measurement opens that historical data set for further observation.
