Lecroy LA314H

The LeCroy LA314H has four channels and a 470 MHz bandwidth. While digital scopes have become much more common than analog oscilloscopes, if you prefer analog, the LeCroy LA314H Oscilloscope offers the highest level of analog performance available today. Analog oscilloscopes offer unique benefits in solving specific measurement problems. The analog display provides important clues on relative frequency content of signals mixed together or the occurrence of low rep-rate events on repetitive signals. The LA314H has a meshless CRT and effectively displays these "grey scaling" and "persistence" effects; and the LA314H's ultrafast display update rate lets you see how the waveforms behave in real time. The standard multipurpose trigger, wide input offset range, comprehensive cursors and counter make the LA314H a perfect choice when you need the specific functionality of an analog oscilloscope.
