(1986). 19, 67-68 Digital Oscilloscope with Segmentable Memories A segmentable 32K x 8 bit memory in each channel of the LeCroy 9400 digital oscilloscope enables logging of suc- cessive events on trigger command. This allows, at one extreme, 250 waveforms of 125 words to be logged well within 50 ms; at the other, 8 wave- forms of 2500 words within 2ms. In window mode memory segmentation offers another significant benefit, as two trigger levels can be set symmetrically or asymmetrically around the zero-base level. Triggering will take place only when the signal in positive or negative direction exceeds the present levels: i.e. 'normal within window' signals do not set the triggers. Combining memory seg- mentation and window triggering, the user can log excessive signals over time. The oscilloscope has a bandwidth of 68 NEW COMMERCIAL PRODUCTS 125 MHz, an ADC rate of 100 mega- samples s-1 for transients and 5,000 megasamples s-~ for repetitive signals. It has one GPIB, two RS232-C standard interfaces, and a built in digital plotter driver. LeCroy Research Systems Ltd, Elms Court, Botley,
