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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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).
