The Literunner LP142 digital oscilloscope features vertical accuracy within 2% and horizontal accuracy of 50 ppm, or 0.005%. LeCroy Corp. designed the device with a housing that measures 6.5 x 8.25 x 7 in., a built-in 3.5-in. floppy disk drive, graphics printer and internal five-digit hardware frequency counter. It features a 500-megasample-per-second rate, 100-MHz bandwidth and 5x oversampling with viewing signals up to 200 µs in duration. It also has 100-kB-per-channel memory and three-way data storage capability. Two cursors allow the user to measure frequency, voltage and time differentials, and voltage at time of a specific waveform. The features of the LP142 make it suitable for manufacturing and service applications.
