The spot position is controlled by the monolithic display processor MDS Failing waveforms can be transferred to the optional memory card.
This is realized by increasing the beam ON control timing by nsec. DS is data space. Modular architecture allows easy installation of extended signal processing packages such as Fast Fourier Analysis. The precautions against static electricity are required. On the display board, adjust the potentiometer INT until the expanded trace just appears on the screen. Faster sampling means better single-shot bandwidth, better time resolution and the power to expand waveforms up to times to see details that completely elude other digital oscilloscopes.
The image is a vector type display.
Follow the F power supply disassembly procedure 4. It is used, for example, in spectral analysis where a waveform is sampled and digitized, then msnual by a Dis- crete Fourier Transform DFT.
Service manual of Lecroy A DSO
At this moment the processor starts to read data from memory address hexOOOO. Remove the four screws which secure the F to the left panel and the board can now be removed vertically from the DSO, making sure that the EHT cable is kept away from boards, as some charge may remain. Graphics Density and Plot size are menu manuzl.
LeCroy Sari 1 Germany: RIS is a high-precision, digitizing technique that enables measurement of repetitive signals to a bandwidth of MHz with an effective sampling interval of psec and lecriy resolution of 5 psec. High Resolution – Allows filtering of the digitized sig- nals, whether they are single-shot or repetitive, in order to increase the resolution of the displayed trace from 8 bits to 11 bits in steps of 0.
DACs are not on the internal busses. Users can obtain time and frequency values simul- taneously and compare phases of the various frequency components with each other. A points waveform will use 2 bytes per point in word format plus bytes of waveform descriptor, for a total of 950.
For one-axis draw vectors, the maximum rate is different for X ldcroy Y because the length in millimeters on the screen of the same deltaX and deltaY is different. If the test fails, the Oscilloscope can perform up to six actions hardcopy, storage to memory card, TTL pulse, etc The A main processor can read back the display memory in order to plot the screen contents via the external printer port or for test purposes.
Check mahual “OK” at the three sampling frequencies. I will just move to a manufacturer were manuals are free or low cost. The customer must purchase his own accessories since we do not supply them.
Waveforms and display information manuap pres- ented using vector linear graphics. I can tell you with candor that willingness to help with tech support is not without its hazards.
Stop electronic waste – fix it yourself
A simple timing diagram is given in figure 9. Remote read and write All waveform formats including complex can be read by computer for storage or further processing. It is used to capture, analyze, display and archive electrical waveforms in fields such as analog and digital engineering, automated test and measurement, telecommunication and electronics research. The LeCroy A Lecry Digital Oscilloscope is a powerful high— resolution instrument for waveform recording and sophisticated analysis.
Send me an email at Dan. Fully Featured with Remote Control- All the front-panel commands used to drive the memory card system are ldcroy through re- mote control. FFT of a 1 Hz amplitude modulated square wave, recorded over 50, points, shows harmonics up to 51 kHz.
The has 4 x 50K, 1 6-bit word memories which can be used both as ref- erence or as function memories. Electronic Enterprises, Israel:
