The LeCroy 9400A Digital Oscilloscope is a powerful
general-purpose tool for waveform recording and analysis.
Combining ease of use with a comprehensive range of
measurement and processing capabilities, it enables
extremely precise measurements.
The LeCroy 9400A provides 175 MHz bandwidth, 100
megasamples/sec 8-bit ADCs, ± 2 % DC accuracy (± 1 %
optional), 32K memory per channel, and up to 192K of
waveform storage memory. It is fully programmable over
RS-232-C or GPIB interfaces. Plotter drivers enable color
archiving via a wide range of digital plotters.
High bandwidth and precision - Two independent channels,
each with 175 MHz bandwidth and a high-performance 8-bit
ADC, handle input signals with better than +2% DC accuracy
(±1% optional). The 9400A features sampling rates of 100
megasamples/ sec for transient events. Long memories and a
versatile cursor system (including voltage, time and
cross-hair cursors), give time measurements with an accuracy
of ±0.02% ofthe time-base setting, and resolution of ±0.002%
High-resolution display-The 9400A’s large display screen
produces bright, stable, razor-sharp pictures of your signal
under any repetition rate conditions. Very accurate signal
comparisons are possible as up to four waveforms (live,
expanded or processed) can be displayed simultaneously on
the high-resolution screen (1024 x 1024 pixels).
Long memories - The long 32K acquisition memories of the
9400A Digital Oscilloscope capture waveforms with high
fidelity. At similar time-base settings, the 9400A’s long
memories allow sampling rates up to 25 times faster than
that of instruments which have only 1K of acquisition memory
(see graph below). Faster sampling rates ensure higher
single-shot bandwidth as well as significantly reducing
problems caused by undersampling and aliasing. The 9400A’s
long memories allow displayed waveforms to be expanded up to
100 times to show the finest signal details.
Transient recording - With a sampling rate of 100
megasamples/sec, the 9400A is an extremely powerful
transient recorder. Long 32K data point acquisition
memories, combined with a continuously adjustable trigger
(from 100% pre-trigger to 10,000 divisions post-trigger at
any time-base setting), ensure that rare events cannot be
missed. Both channels are sampled simultaneously so that
exact time correlation is maintained between channels.
Full programmability - All the 9400A’s front-panel controls
are fully programmable via the two RS-232-C Interface ports
or the GPIB port. A single push-button initiates a screen
dump for accurate color hard copies of the display via a
wide range of digital plotters. The GPIB comes complete with
LeCroy “MASP” Software offering computer control and mass
storage on any PC compatible with the IBM® standard.
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,
square, square-root, full arithmetic, FFT spectral analysis,
and Extrema monitoring.
Mass storage and remote control - A sophisticated mass
storage and remote control package is available to assist
users involved in automated and computer-aided testing.
Convenient portability for field applications is also
provided by a lap-top computer.
