Initial inspection indicate no high voltage to the CRT it looks like the power FET’s don’t seem to be switching, zero activity in the small transformer that feeds the high tension transformer to CRT internal field.

Multi-source trigger operational modes: Lutronic, 42 Eastern Europe: Triggers on opposite slopes of pulses narrower than manuao value in the range 2. Choosing IC with EN signal 2.

The deflection angle depends slightly on the anode voltage. Press “More Consts” and “Phase Constants” button.

The amplifier is provided with an OFF command to disable it in case of overheat or when the protection circuitry detects a problem. The middle and the lower trace show the two amplitude spectra.

The displacement velocity is limited by the power supply and the inductance of the deflection yoke. The HMSA hybrid is a combination manial four sample and hold, numbered 1 to 4 which divide the signal in four branches.

The 11 kV is made through a high voltage times five multiplier. You acknowledge that all comments express the views and opinions of the original author and not those of the administrator. An additional K of RAM is available for waveform processing, storage and display. The deflection yoke can be removed from the cathode ray tube. Lecroy does not archive this service manual, and I have been unable to locate a copy.


The 8 intensity bits are converted to analog current by an 8-bit DAC.

This is realized by increasing the beam ON control timing by nsec. Top and bottom covers 4. Avantec AS 02 Pakistan: All Epson and Epson Compatible printers are likely to work if the switches are set properly.

Pulse parameters – Up to twenty signal characteris- tics risetime, falltime, RMS voltage, manul. Specifications subject to change without notice. Box Meyrin 1 -Geneva, Switzerland Telephone: Time domain and frequency domain data can be displayed simultaneously up to 4 wave- forms. Reference memories C and D: Manual linearity Test Procedure Set scope to: The Eproms can be removed using an IC extractor.

With LeCroy oscilloscopes, signals may be acquired and processed simultaneously using Channels 1 and 2 1 to 4 in the The power supply is the next item to check before proceeding to more detailed troubleshooting. Remove the six screws at the top, bottom, left and right of the front panel The main features of the bus are summarized below: The phosphor is orange L5C.


Switch on the power using the power switch on the rear panel. The principles of GPIB are quite simple – the system must wait for all users, and lines are wire ORed so that all can pull the lines down.

They are selected through simple menus that allow functions to be chained together allowing more complex computations. Therefore the two LSBs are not used. Spectrum Display Formats and Scaling Frequency scale: BK Precision User Manual.

Hard copies are made at the touch of a button on a wide range of digital plotters and printers. Santos, Canada: All the rotary knobs must be removed, which means taking off all the caps careful, soft plastic and loosening the screws and nuts.

The current is measured through a shunt resistor of 0. The cycle is then exactly the same. The analog feel is en- hanced by the rapid instrument response and the fact that waveforms are presented instantly on a bright high- resolution screen.

The SMART trigger facility provides a complete range of sophisticated and versatile trigger features.
