Oscilloscope to view mains power

hook up oscilloscope

If you're trying to measure a very low-voltage signal though, you may need to use 1X. If isolated, I believe you would just be setting that portion of the circuit at grounds reference level and everything else is relative to it. This is just my own personal opinion but any decent 2-channel scope should work. Using the horizontal system, you can adjust how many periods of a waveform you want to see. Ideally, a wave going through a voltage follower should not change at all. Zoom in, and set a vertical cursor at the first edge.

Probe response correction For a high-bandwidth active probe, probe response correction has become increasingly common. Peak amplitude, on the other hand, only measures how high or low a signal is past 0V. Make sure the trigger isn't higher than the tallest peak of your waveform. Example: the second byte on the 1st screenshot, starting with the 2 narrow pulses. The resulting display should be a simple straight line midway between the second and third vertical division above the centerline.

This will show all the plugs, in the firing order, in 1 trace. I want to know what a working axis looks like first. Notes: In order for students to answer this question, they must review the internal operation of an oscilloscope. Connect the Probe and Turn the Scope On Connect your probe to the first channel on your scope, and turn it on. Cursors You can use the same measurement techniques as before for measuring properties of the wave, or you can use the cursors.

Hookup RF Generator and Oscilloscope?? Help PLEASE.

There are a variety of probe types out there, the most common of which is the passive probe, included with most scopes. But if you're reading this tutorial, that probably means you'd rather not read the manual, so let's get started. Many scope displays are situated next to a set of about five buttons -- either to the side or below the display. Never connect the ground shield return of the scope to the hot side of the mains. The ground clips on your probes are connected to Earth ground by means of the oscilloscope power plug, in a roundabout fashion. For example, if you want to verify that the output from a pin of an integrated circuit is emitting a square wave, touch the oscilloscope probe to the pin and look at the display on the scope.

How to Use an Oscilloscope

If at all possible, keep both the input leads of the probe tip as well as the loop area of connection as small as possible. The impact of input impedance is more apparent when measuring very high frequency signals, and the probe you use may have to help compensate for it. I like digital better for slower signals, say less than 10khz. The bandwidth of an oscilloscope or probe is always a key banner specification, but the measurement system is more than just the oscilloscope and the probe. I have a hitachi oscilloscope v-422 but I need to do this with out killing myself and blowing up the scope.

Oscilloscopes come in two varieties: analog and digital I'll be using a digital scope in this tutorial. What display control s need to be adjusted on the oscilloscope in order to show a normal-looking wave on the screen? I just can't recall the last time I took either downstairs to work on a car. Beyond the passive attenuated probe, there are a variety of other probes out there. There is nothing inherently different between an antenna and any old piece of metal. If your waveform is periodic, the trigger can be manipulated to keep the display static and unflinching. Triggering allows you to horizontally align repetitions of this signal. Before continuing on the to next step, set your trigger level to the center of the screen as shown in fig 3.

Basically, it allows you to zoom in and out along the y axis. There are a variety of amplitude measurements including peak-to-peak amplitude, which measures the absolute difference between a high and low voltage point of a signal. Again 9 bits, so the next one should be a low bit, the stop bit. Do I hook the osc up to red and blue? The difference in time between the cursors is 11. Probing, Triggering, and Scaling Tips Once you've compensated your probe, it's time to measure a real signal! The best way to do this safely is to put your scope in differential mode.

Can't really go wrong with a Tektronix 465, got one sitting on my bench. Measure Twice, Cut Once With a signal scoped, triggered, and scaled, it comes time to measure transients, periods, and other waveform properties. We cannot directly measure the frequency on the oscilloscope, but we can measure a closely related parameter called period; the period of a wave is the amount of time it takes to complete one full cycle. Is it saying it can handle up to 400V peak? If you want to measure voltage from an outlet, just use your regular multimeter. The only thing slightly automotive I've done with it is adjust the governor on my push mower.
