LA302	LeCroy 100 MHz, 3 Ch. Analog Oscilloscope - Discontinued - suggested replacement: Iwatsu SS-7811

Main Features

With three channels and up to 200 MHz bandwidth, the LA302 and LA303 analog oscilloscopes offer a high level of performance for relatively low cost. 

Analog oscilloscopes offer unique benefits in solving specific measurement problems. The analog display provides important clues about the relative frequency content of signals mixed together or the occurrence of low rep-rate events on repetitive signals. The analog display effectively displays these "grey scaling" and "persistence" effects. The ultrafast display update rate lets you see how the waveforms behave in real time. 

The LA302 and LA303 are perfect instruments for service and educational applications. Equipped with extensive TV triggering, both scopes are excellent for video testing. 

The standard multipurpose trigger, five-digit counter, and comprehensive cursors make the LA302 and LA303 truly universal oscilloscopes.

Features

Convenient fine-adjustment mode

Pressing FINE and turning the knob enables slow scrolling of waveforms ­ a function comparable to a digital storage scope's roll mode.

Line triggering provided for AC line measurement

AC line-related measurement of various frequencies can be obtained.

Third channel input

CH3 provides three sensitivity levels for a wider range of measurements.

Input with probe sensor function

When using a probe, the range display is automatically calibrated by detecting 10:1 or 100:1 with the probe sensor.
