Specification :

With the storage menu and triggering function concentrated to assure safe use by anyone engaged in the production and a clear panel layout showing operations at a glance the DCS-7000 Series of oscilloscopes are easy-to-use models even for beginners in spite of the many versatile functions packed in each unit. The maximum sampling rate of 40 MS/ s ( DCS-7040) enables advanced waveform observations and an analog function ( 50 MHz) is also incorporated so that each model can play two roles of digital and analog. Each channel has a 4K-word acquisition memory. The peak detector and overwriting functions are provided in pursuit of a compatibility between the ease of use and the high functionality. Optional interfaces can also be installed so the waveforms displayed on the CRT can be hard-copied on a plotter or a special printer.
