LeCroy LA354 500MHz 4 Channel Analog Oscilloscope LCD
Up for sale is a great condition LeCroy LA354 500MHz analog oscilloscope. This unit has been tested and is in great working condition. The unit will come with the pictured front cover and a new power cord. There are no probes or manuals included with this unit, just what you see in the pictures.
This scope is in like new condition and performs flawlessly. There are a few scratches on the handle, but everything else is in great condition. The front panel and display are flawless, with no scratches or any marring. The knobs turn easily and responsively, and the buttons press firmly. The carry handle locks into place and securely braces the unit as a kickstand. The rubber feet and the plastic accessory pouch are in great condition.
This LA354 has the Serial Number - 0157271.
Whether or not you are looking for a great general scope or specifically an analog scope to compliment the digital scopes in you lab, the LeCroy LA354 is the perfect choice.
The LA354 is a 4 channel - color LCD display, analog storage oscilloscope. This high-end analog oscilloscope for the digital age has a conservatively rated 500Mhz band width. This scope has variable persistence in a choice of colors which is exceptional for glitch capture and single event viewing. It has a full set range of cursor measurements and built in frequency counter.
For years, engineers have insisted on oscilloscopes that offer both ultra-high brightness and storage capability in a single unit; capabilities that until now were only available from digital oscilloscopes. Unfortunately, digital oscilloscopes lack one very important capability - the ability to observe unanticipated waveforms. Only analog oscilloscope can do this. Moreover, both digital and analog scopes have difficulty observing noise waveforms, jitter, and detailed video signal waveforms using delay sweeps.
The new LA-354 from LeCroy solve all of these problems. Its ultra-high writing speed and scan converter allow it to capture and store even the most infrequent and irregular signals, providing the ultimate waveform observation tool for researchers and engineers.
The LA354 has an Analog Bandwidth of 500 MHz and a storage writing speed of 5 div/ns.
Analog oscilloscopes offer unique benefits in solving specific measurement problems. The analog display provides important clues to relative frequency content of signals mixed together or the occurrence of low rep-rate events on repetitive signals. The LA354's scan- converter tube, combined with a TFT-color LCD screen, effectively displays and stores these "grey scaling" and "persistence" effects with up to 5 div/ns writing speed, and its ultra fast display update rate lets you see how the waveforms behave in real time.
The standard multipurpose trigger, wide- input offset range, 51/2-digit frequency counter, and comprehensive cursors make the LA354 a truly universal storage oscilloscope.
