LeCroy 470 MHz, 4 Ch. Analog Oscilloscope - Discontinued - no replacement |
With four channels and wide 470 MHz bandwidth, these leading-edge analog oscilloscopes offer the highest level of 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 LA314's meshless CRT effectively displays these "grey scaling" and "persistence" effects; and the LA314'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 LA314s truly universal oscilloscopes.

DC - 470 MHz, 4-CH, 10 traces
Four channels up to 470 MHz are available, with CH1 and CH2 boasting the widest frequency range with highest sensitivity (2mV/div). The fastest sweep speed is 500 ps/div.
Suitable for the observation of small signals superimposed on large signals. The DC input offset function features an offset equivalent to ±500 div. max, which can be applied to CH1 or CH2.
Counter measurement function
Built-in 5 digit counter for frequencies up to 470 MHz.
Save/Recall up to 256 panel settings Just turn the FUNCTION knob to recall panel setups. Stores up to 256 settings in memory.
Dedicated power supplies for 2 FET probes. Controls DC offset voltage of each probe as well.
TV triggering is available for NTSC, PAL, (SECAM) and HDTV. Field (EVEN, ODD, BOTH) and line select functions are included.
Easy observation of TV video signals with fluctuating average voltage. Back porch level of composite signals is fixed to ground level for display.
