DUAL 125 MHz DIGITAL OSCILLOSCOPE

Information

DUAL 125MHz DIGITAL Oscilloscope The LeCroy 9400 Dual Digital Oscilloscope is a powerful general purpose tool for waveform measurements. Designed to operate as easily as your familiar analog Oscilloscope, the 9400 brings you a whole new range of capabilities to measure and characterize your waveforms with greater precision and confidence. With the 9400 you gain : HIGHER PRECISION Two independent 125 MHz channels, each with a high performance 8-bit ADC, convert your input signals with better than 1% accuracy. Each input is sampled at a maximum rate of 5 Gigasample/sec for repetitive waveforms and 100 Megasample/sec for single events. The high sampling rate combined with extremely long 32,000 data point acquisition memories, permit time measurements with an accuracy of 0.002%. The 9400’s easy to use Voltage, Time and Crosshair Cursors assist you in making precise measurements. HIGH RESOLUTION DISPLAY The large, high resolution display produces bright, stable, razor Sharp pictures of your signal under any rate conditions. Up to 4 waveforms can be displayed simultaneously. The high resolution (1024 x 1024 pixels) display permits very accurate comparisons and waveform measurements. With "x100” timescale expansion, you zoom in on details for analysis and exact cursor placement. SINGLE TRANSIENT RECORDING The 9400 is an extremely powerful transient recorder with a maximum sampling rate of 100 Megasample/sec. Rare events cannot be missed. The long 32,000 data point acquisition memories, combined with the continuously adjustable trigger (from 100% pre-trigger to 10,000 x time/div post-trigger), give unparalleled flexibility. Both channels are sampled simultaneously and exact time correlation between channels is maintained. FULL PROGRAMMABILITY All the 9400’s front panel knobs and push-buttons are fully programmable. RS232C and GPIB interfaces facilitate computer aided testing, remote-control operation and ATE applications. Up to 7 different front-panel setups can be stored and easily recalled to simplify successive test operations. A single pushbutton initiates a Screen Dump for accurate hard copies of the display via a wide range of digital plotters. SIGNAL PROCESSING CAPABILITY Elaborate signal processing can be performed on the digitally stored waveform. For specific application analysis, the captured waveform can be transferred to a computer and studied with your own Software. Processed data can then be transferred back to the 9400 for reference. For front end data reduction and processing, LeCroy offers optional firmware packages including signal averaging, arithmetic array operations and Fast Fourier Transforms.

Information

The present Service Manual applies to both the 9400 and the 9400À DSOs. Both models are called 9400 when the information applies equally to both oscilloscopes. Where the two models have distinct features, the model number 9400 or 9400A is explicitly stated. The chief purpose of this manual is to provide information for technicians, mainly authorized LeCroy repair office personnel, who are responsible for repairs and modifications to the LeCroy 9400.9400A DSOs. To this end, the descriptions provided are intended to be of sufficient depth to enable faults to be diagnosed to the level of the relevant board, so that the customer can be quickly supported by exchange of boards. In many cases the fault may be corrected at the local LeCroy office, but there are several areas of the circuitry where replacement of a part would need to be followed by calibration which could be done only with specialized equipment available at the main LeCroy establishments. Calibration procedures are given in this manual only for those areas which could be serviced locally. A DSO repair intervention at board exchange level can only be done by qualified technicians who have followed the basic 9400.9400A service training. LeCroy also offers these courses to customers. In addition, there is a very comprehensive 9400 Adjustment and Calibration Software Package CALS0FT (order codes CS01/CS02) based on the IBM PC or a compatible computer. This Software package is also available to customers, as well as all the hardware making up the 9400 Automated Calibration System (order code CS-S) which is used in all LeCroy service offices to ensure full performance of the instrument. This system provides Calibration Certificates traceable to NBS. LeCroy also offers training classes on DSO calibration. This manual could be improved by the inclusion of useful information resulting from detection and correction of faults in 9400.9400A DSOs at any LeCroy office. Each time a DSO is opened, an official LeCroy repair report should be sent to LeCroy S.A., attention Customer Service. The information is entered into a centrally maintained DSO data base for failure analysis and engineering feedback. Before undertaking any work on the 9400 DSO you should read the next sections - WARNINGS and VALID RANGE of FIELD MAINTENANCE.
