The 9304A and 9304AM are general purpose 200 MHz four channel digital
oscilloscopes. They capture single-shot events at up to 100 MS/s, and repetitive
signals at 10 GS/s. Record lengths up to 200k points pr
resolution, and allow fast digitizing of long
segmented, for minimum dead time between acquisitions.
Live waveforms on the main timebase may be viewed simultaneously with up to
3 expansions, show
highlights on the main trace.
The LeCroy ProBus intelligent probe system allows automatic sensing of the
probe type. For LeCroy's active FET probes it also provides variable offset at the
probe tip. Of
SMART Trigger modes like Glitch, Window and Dropout allow you to capture
precisely the events of interest.
