To zero - so you won't see a thing! So set it to about ¾ full brightness. Sets the amount of electrons hitting the phosphor screen and it can be set it Oscilloscope it is one of the controls to the right (black button in the greenĪrea). Make sure that X-Y mode is not selected as this disables the timebase - on this The time for going from left to right covering the whole display is 10x05.ms =ĥms (a frequency of 200Hz - 200 times a second) - for finding the beam this is (ray) is moved through each horizontal division over the period of 0.5ms. The timebase (picture to left) is set to 0.5ms/DIV which means that the beam Screen and it's calibrated in horizontal divisions (the black grid on the front Timebase sets the time that the beam is scanned from left to right on the Incorrectly will result in an invisible beam. Note: You have to set all of these appropriately - setting any one

The first thing you need to know about it is how to find the beam! Unlike aĭigital scope it does not test the inputs and set itself up for the mostĪppropriate display mode for you - with the CRT you have to do this yourself. Evenġ0mA at 250Vac can kill and voltages in the oscilloscope are far Voltages are extremely dangerous they are high current and high voltage. Note: Never open the oscilloscope as these Phosphor screen that fluoresces when hit by an electron. Using very high voltages (1000s of volts) and guided by electric fields to the Electrons are forced off a plate at one end The cathode ray oscilloscope (above) is the original oscilloscope and usesĪ high voltage cathode ray tube. How to use an oscilloscope (or CRT) : Find the beam! You getting into trouble if someone else was using it. Internal floppy drive or over the network to your hard disk - this will save Someone else has been using it - save the settings (and possibly data) to an Note: Before hitting the reset button - if Get you out of all trouble as you can set up digital oscilloscopes in manyĭifferent ways and they often have options buried in the depths of the menu Tip: For a digital oscilloscope all you need to know is the location of the Oscilloscope controls are still relevant today
