LeCroy - 9400A Oscilloscope

The LeCroy 9400A digital oscilloscope is a powerful universal instrument for recording and analyzing waveforms. Thanks to the combination of user-friendliness and a wide range of measurement and processing capabilities, it enables highly accurate measurements. The LeCroy 9400A offers a bandwidth of 175 MHz, 8-bit ADCs with a sampling rate of 100 megasamples/sec, a DC accuracy of ±2% (±1% optional), 32K memory per channel and up to 192K waveform memory. It is fully programmable via RS-232-C or GPIB interface. Plotter drivers enable color archival through a wide range of digital plotters. High bandwidth and precision - Two independent channels, each with a bandwidth of 175 MHz and a powerful 8-bit ADC, handle input signals with a DC accuracy better than +2% (±1% optional). The 9400A has sampling rates of 100 megasamples/sec for transient events. Thanks to the long memories and the versatile cursor system (including voltage, time, and cross cursors), time measurements can be performed with an accuracy of ±0.02% of the set time base and a resolution of ±0.002% of full scale. The large display of the 9400A produces clear, stable, and razor-sharp images of your signal, regardless of the repetition rate. Very precise signal comparisons are possible, as up to four waveforms (live, extended, or edited) can be displayed simultaneously on the high-resolution screen (1024 x 1024 pixels). The long 32K acquisition memories of the 9400A digital oscilloscope capture waveforms with high fidelity. At comparable time-base settings, the long memories of the 9400A enable sampling frequencies up to 25 times faster than instruments with only 1K acquisition memory (see the figure below). Faster sampling frequencies provide higher bandwidth per measurement and reduce problems caused by undersampling to a significant extent. The long memories of the 9400A allow displayed waveforms to be magnified up to 100 times, so even the finest signal details become visible. Transient recording - With a sampling rate of 100 megasamples/sec, the 9400A is an extremely powerful transient recorder. Long memories for 32K data points, combined with a continuously adjustable trigger (from 100% pre-trigger to 10,000 divisions post-trigger at every time-base setting), ensure that rare events are not missed. Both channels are sampled simultaneously, so exact time correlation between channels is preserved. Full programmability - All controls on the front panel of the 9400A are fully programmable via the two RS-232-C interface ports or the GPIB port. With the push of a button, a screen dump is made for precise color prints of the display via a wide range of digital plotters. The GPIB port is supplied with the LeCroy “MASP” software, offering computer control and mass storage on any IBM-compatible PC. Signal processing - The waveform processing options extend the applications of the 9400A to high-bandwidth signal characterization, as well as mathematical and spectral analysis. The routines include averaging (summed and continuous), smoothing, integration, differentiation, squaring, square-root extraction, full arithmetic, FFT spectral analysis, and extrema monitoring.
