Even some oscilloscopes with high sampling rates may not be able to accurately capture waveforms if the memory size is not long enough for the required monitoring period. This limitation is due to the necessary drop in sampling rate, which occurs if the recording memory is not long enough. A larger recording memory not only increases the monitoring time, but also enables users to maintain a high sampling rate thus ensuring accurate waveform representation. In addition, the zoom function can be used to simultaneously view enlarged images on one or two segments of a waveform captured in the large memory.

When working with data captured in the large recording memory, the amount of information appearing on the display varies greatly depending on how the data are presented. The difference occur depending on whether you choose to display all points in a captured waveform, or just major values, such as maximum and minimum values, in a given segment on the waveform. The DL1700E Series provides fast screen updating in all-points display mode, so you won't miss abnormal phenomena or have slow responses to instrument controls.

"I want to find the serial data with a particular serial pattern", "I need to search for surge pulses of less than 30ns", "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.

The history memory function divides the large recording memory into a number of blocks and automatically saves up to 2048 previously captured waveforms. Increases the number of screens saved to history memory by setting a shorter record length.
 

The history search function is useful for quickly finding abnormal waveform data stored in history memory. This function lets you automatically search for desired waveforms based on whether or not a signal passes through a user-defined area on the screen. You can also conduct searches based on waveform parameters.

Calculates statistical information based on the parameter values for waveforms stored in history memory. This function calculates and displays a parameter's maximum value, minimum value, average value, and standard deviation. You can check the parameters for every waveform in history memory.
