The instrument features lectoy 8-bit ADCs, 50K of non-volatile acquisition memory per channel, K of additional waveform storage memory, extensive pulse parameter analysis, and a highly sophisticated trigger system leecroy capture the most complex signals, including spikes and glitches. PS is program space. The design of the analog X and Y ramp generator limits the precision to about 1 X. Up to MHz using HF trigger coupling. Highest side lobe indicates the reduction in leakage of signal components into neighboring frequency bins.

For automated test applications all the front-panel controls, including cursor positions and inter- nal functions, are fully programmable over RSC or GPIB interfaces.

Color archiving – Provides color hard copies of the screen using a wide range of digital plotters. The gain curve is the dependence of the front end variable gain on the manuzl bit DAC. The following settings are assumed for the scope: To improve the signal-to-noise ratio on the phase-in- coherent FM signal, 66 spectra are averaged bottom trace.


Top and bottom covers 4. The power supply is the next item to check before proceeding to more detailed troubleshooting. The waveform in Channel 1 is contained in the mask in Memory C all points inside the mask.

Fully Featured with Remote Control- All the front-panel commands used to drive the memory card system are available through re- mote control. Versatile display formats – Frequency-domain data may be presented as magnitude, phase, real, imagi- nary, complex, log-power and log-PSD Power Spectral Density. Reference memories C and D: Character Set Display 4. Above, a ramp top trace and a square wave lower trace are multiplied leceoy er.

The following trigger classes and operational modes are available: Time and date information is automatically recorded for each segment. The transform size de- fines the decimation applied to the signal after the acquisition.

Pulse parameters – Up to twenty signal characteristics risetime, falltime, RMS voltage, etc. Although the administrator will attempt to moderate comments, it is impossible for every comment to have been moderated at any given time. Scan by Paladinmicro – paladin paladinmicro. Hierarchical lecryo is unconnected 3. Therefore the two LSBs are not used.

Make sure the mains cable stays plugged into the line filter.

The adjustment of the trigger level is described in the manuao and calibration procedure of the FA-7 front end. When replacing a push button, take great care to achieve good alignment, to avoid sticking when the button is used. DACs are not on the internal busses. The SMART trigger facility provides a complete range of sophisticated and versatile trigger features. An additional K of RAM is available for waveform processing, storage and display.


Stop electronic waste – fix it yourself

Same top and bottom trace definition as in the previous graph. To further confude the issue most PC computers use a pin D connector for both the serial and parallel connections. Addi- tion, subtraction, multiplication, and ratio on any two waveforms. You acknowledge that all comments express the views and opinions of the original author and not those of the administrator.

For “move” vectors, the rate is not set OFF from leccroy 0 to 3. Operates on live waveforms with full cursor readout. It is a LeCroy proprietary gate array. Lcroy off all the traces except CHI. Exceptional processing power means these values are instantaneously updated with each acquisition.

Tektronix PS or equivalent. The replacement board is supplied without this PAL. All signals except RREQ remain low until access can be granted. The memory is in use: Adjust the size of the display, in order to get 5mm gap between the middle of the image lines top, bottom, left, right and the CRT lines. In the following list, plotter address 7 is given as an example.
