The YOKOGAWA SignalExplorer DL7100 was designed to sat- isfy the key feature requirements for waveform measuring systems. These features are: ● Simple and accurate capturing of complex signals ● High-speed extraction and screen display of desired information from large volumes of captured data Our goal was to create a waveform measuring system that truly meets your needs. ● Maximum 1 GS/s ● 500 MHz analog bandwidth ● Large recording memory (maximum 8 MW with 701420, 2 MW with 701410) ● 4 analog input channels and 16-bit logic input (optional) ● Newly developed DSE chip for high-speed screen updating ● Standard equipped with SCSI, GP-IB, SERIAL (RS-232), and Centronics interfaces ● History search and serial pattern search functions ● Easy to use ● 1 MW all-points display (*1) and screen updating 30 times per second so that you can detect problems more reliably The DL7100 has a new Data Stream Engine "DSE" (*2) IC de- signed to handle large amounts of data and provide fast screen update rates. This new DSE combined with an "all-points dis- play" technique, which plots all data points without compres- sion, makes it easy to capture abnormal signals such as high- speed surge signals. The DL7100 updates the display 30 times per second even when using 1 Mword of memory and the all- points display. ● 4 analog channels and 16-bit logic input (optional) for simultaneous measurement on a total of 20 channels. Most oscilloscopes limit you to two or four channels of analog data. It is difficult to set up multiple instruments to evaluate analog and logic signals at the same time. The DL7100 has four analog inputs plus an additional sixteen logic inputs (option). Set up complex triggers and capture ana- log and digital information. All your data is on a single display. ●Serial pattern search and Zooming You can set a serial pattern of up to 64 bits and then automati- cally search for that pattern in the stored data. When that spe- cific pattern is located it will be displayed in the zoom window. Two zoom windows can be used to compare different areas. You can also use pattern search to count rising and falling edges and detect any edge. ● History memory and History Search With most oscilloscopes, new waveform data replaces previous data with each acquisition. Even if you press the STOP key, an abnormal signal waveform can be lost. The History memory can save up to 2048 previous acquisitions. This makes it possible to store waveforms with events not even covered by trigger settings. The History Search function will find the stored waveform that has abnormal components. You can specify a zone and select just waveforms with components that pass or bypass the speci- fied zone. ● Simple and enhanced trigger functions Simple edge triggering may not be good enough to capture the desired signal. Enhanced trigger functions are standard on the DL7100. They include A->B(n), A delay B, OR, Pattern, Pulse width, TV, Logic, and external. It is easy to jump between enhanced and simple edge triggering.
