1 GHz带宽
The 9384 series digital storage oscilloscope opens up new horizons for engineers
and scientists at the leading edge of technological developments. With 1 GHz
bandwidth and long acquisition memories, it is now possible to reveal previously
hidden waveform details. Narrow glitches are more accurately defined; risetime
measurements below 1 nanosecond are more precise; and high-frequency content,
filtered out in lower bandwidth systems, is retained, thereby preserving signal
amplitudes and overall signal integrity. Edge Triggering to 1GHz and LeCroy's
powerful Smart™ Trigger modes like:Glitch, Pattern, Dropout, Interval, Exclusion
and TV enable you to capture precisely the events of interest.
4 GS/s采样速率
The 9384 samples simultaneously on all channels at 1 GS/s. Thus, it is ideal for
demanding high speed applications. In addition, two channels can be combined to
provide a sample rate of 2 GS/s or 4 GS/s in single channel mode. Finer
horizontal resolution and accuracy are assured by high sample rates. This is
especially critical in digital design where unpredictable circuit behavior needs
to be identified and analyzed in detail to be fully understood. Together with
this excellent single-shot performance the 9384 series also provides a sample
rate equivalent to 10 GS/s for repetitive signals. The innovative peak-detect
mode enables glitch capture even at the slowest time settings without loss of
precision.
8M Points存储深度
Channel record lengths of 100k, 500k and 2M are available on the 9384. The
memory power is revealed when the user seeks to sample at the highest speed over
many timebase settings. DSO's with less memory may boast a high sample rate for
short waveforms, but only LeCroy's long memory oscilloscope can deliver high
sample rates for long waveforms. To exploit this capability to its fullest, the
LeCroy 9384AL combines its channel acquisition memories to give the user up to 8
million sample points, thereby providing the waveform detail required on long
and complex signals.
The combined capabilities of the 9384 place it in the forefront of DSO
capability.
精确采集
1 GHz bandwidth results in greater accuracy of amplitude and risetime
measurements for high frequency signals and true representation of high speed
digital and analog signals.
高速采样率
The 9384 provides maximum sample rates of 1 GS/s, 2 GS/s, and 4 GS/s for greater
waveform fidelity, excellent zoom detail, protection against aliasing, precision
time resolution and wider frequency spectrum.
通道存储和通道交替
Capturing long time windows single-shot requires long memory. LeCroy, the
company that invented long memory DSO's, provides three memory selections:100k
points per channel standard, 500k points per channel with the “M” and “TM”
versions, and 2M points per channel with the “AL” version.
By interleaving the 4 channels of the 9384AL, the acquisition memory and sample
rate can be increased 4X to provide up to 4 GS/s and up to 8M-points of memory.
The result is that the 9384AL enables you to capture 2 millisecond of signal
duration with 250 ps real time sample resolution.
先进的峰值探测系统
The 9384 series offers an innovative peak detect capture mode. This captures
fast glitches by running the ADC's at a high sampling rate even at slow time
base settings thereby capturing signal details that might have been missed due
to under sampling. At the same time the scope stores the underlying data to
ensure no loss of time precision - unlike other peak detect systems.
SMART触发系统
SMART Trigger functions including Glitch, Pattern, Interval, Exclusion, TV,
Dropout, and State-or-Edge Qualified triggers are available. Pre and
Post-trigger delay are fully variable, Time and Events Holdoff are also
included.
自动参数测量和统计
The 9384 provides more than 40 parametric measurements and their Average,
Highest, Lowest values and Standard Deviation. Pass/Fail testing allows up to 5
parameters to be tested against selectable thresholds. Waveform Limit Testing
can also be performed using Masks which may be defined inside the instrument.
Any failure will activate preprogrammed actions such as Hardcopy, Save, Stop,
Beep, GPIB SRQ, or Pulse Out.
内置打印机
Most printers and plotters can be driven via GPIB, RS-232-C and an optional
Centronics interface. The 9384 offers an optional internal printer which can
produce a 126 X 90 mm full resolution screen dump in under 10 seconds at the
push of a button.
The unique `Strip-Chart' format expands the horizontal axis up to 200 cm/div per
division for viewing fine waveform detail within long memory acquisitions.

概要
Option WP01 provides Summed and Continuous Averaging, Waveform Math Functions,
Extrema and Enhanced Resolution Modes.
Functions can be chained together, allowing complex computations. Waveform
operations can be performed on live, stored, processed or expanded waveforms
without altering the original capture data.
Optional Spectral Analysis Package - WP02
Option WP02 provides comprehensive Spectral Analysis capabilities permitting
the system designer to identify characteristics which may not be apparent in the
time domain. WP02 provides a wide selection of windowing functions as well as
averaging in the frequency domain (see page 59 of Catalog).
Spectral analysis can be performed on repetitive and single-shot waveforms, on
any part or zoomed portions of a waveform up to 4M points, not just the first
10k points of the waveform.
Optional Parameter Analysis Package - WP03
Option WP03 provides extensive parameter analysis capabilities. Detailed
statistical analysis can easily be performed on difficult to measure waveform
phenomena such as amplitude fluctuation and timing jitter. Live histogram
displays represent the statistical distribution of the user selected waveform
parameter measurements. Statistical information can be extracted directly from
the histograms using automatic statistical measurement including max, min,
average, median, and std. deviation (see page 63).
