AND INTERACTIVELY—WHILE VIEWING ON THE
INTERNAL CRT DISPLAYSelect a section of the waveform usingthe time cursors, then select one of aset of waveform manipulation opera-tions (e.g. move feature, delay, ampli-tude) and turn the knob! That is howeasy it is to continuously modify all orpart of a waveform. Time shifts, assmall as 100 ps, amplitude variationson a peak, or changes in signal dura-tion are instantly reflected in the outputsignal. Margin testing or characteriza-tion, with the most complex wave-forms, has never been so easy.
WAVEFORM CREATION HAS
NEVER BEEN EASIERWaveforms can be selected fromlibraries of traditional functions orapplication specific waveforms. Theycan also be created using equations orimported from external sources such asoscilloscopes, or from computer pro-grams and simulator output files. Oncewaveforms are created or captured,they can be further modified usinginternal waveform (array) math pro-cessing. The waveform math functionsinclude basic arithmetic operations,smoothing, integration, differentiation,and convolution.
The highly developed waveform edit-ing capability uses advanced signalprocessing to provide bandlimited cut,paste, insert and offset operations withminimal editing artifacts. Single sampleresolution, further simplifying wave-form creation, is allowed since wave-forms are not constrained to 8 samplemultiples as with most other AWGs.
To simulate real-world signals, theinternal, asynchronous, wide-bandnoise generator is easily used to addcontrolled amounts of noise to yoursignals—simply dial in the noise levelas a percentage of your signal’s ampli-tude. A real timesaver is that if you

FLEXIBLE WAVEFORM
IMPORT AND TRANSFERPull waveforms directly from most digi-tal scopes; Connect a GPIB cablebetween the LW420B and your digitaloscilloscope. Select your scope from alist of commonly available models andbegin importing waveforms.
Waveforms of up to 1 Mpoints in ASCIIor from programs such as MathCad,MATLAB, PSPICE, IQSIM, TOPSIM andothers can be imported from the floppydrive. You can also use a sharewareprogram from LeCroy to convert yourfiles to DIF format and transfer directlyover the GPIB to the LW420B.
When importing or transferring files,you have the choice of over samplingor importing the points exactly as theyare. Once in the WaveStation, all themodification, editing and math toolscan be used to put the waveform inthe shape you need for your task.
FAST SWITCH GROUP

FLEXIBILITY AND
MINIMIZES TEST TIMELeCroy’s Fast Switch Group Sequencecapability enables you to switchbetween many different pre-loadedwaveforms in less then 11 ms.Waveforms will continually play until asequence advance is received from thefront panel or a remote command.Choose to auto advance from sequenceto sequence or choose to jump to thenth sequence in the group. Generate acontinuous output of a sequenceselected from the group, or use theexternal trigger input to initiate a burstor single shot of the selected sequence.
1 Hz frequency resolution over a con-tinuous 6 kHz–400 MHz range providethe flexibility and capability needed togenerate even the most complex anddemanding waveforms.

DRIVE, AND BUILT-IN 9INCH CRTWaveStation provides all the powerneeded to work with long and com-plex waveforms. A built-in hard diskdrive, a 486 processor, up to 24 Mbytesof RAM, and a large internal mono-chrome VGA display make the LW420Aa fast, responsive instrument ideallysuited for the interactive graphicaloperations required in a high-perfor-mance AWG.
DIGITAL OUTPUT OPTIONThe Digital Output option provides 8-bit TTL and ECL digital outputs corre-sponding to the current value of theChannel–1 analog output. The latcheddigital data is held for the duration ofthe sample clock. The digital data,
including the sample clock and itscomplement, are available via rear-panel connectors. The special digitalediting mode is useful for creating andediting byte wide data patterns orselected bits and the standard “cut andpaste” tools available for analog wave-forms can also be used.
