- It directly determines the period and voltage of a signal.
- Indirectly determines the frequency of a signal.
- Determines which part of the signal is DC and which AC.
- Locate breakdowns in a circuit.
- Measure the phase between the two signals.
- Determine what part of the signal is noise and how it varies over time.
How to calibrate the oscilloscope
- First, you have to turn on, to avoid damage to the equipment, a small algorithm is shown on how to do it and to have its correct operation:
- If you have a hand, read the manual of the equipment you are about to use because not all are equal
- Adjust the vertical and horizontal position controls to their approximate average positions (if analog)
- Make sure the power switch is turned off, and the intensity adjustment control is at the lowest level
- Make sure the int of shooting mode is in AUTO
- connect the AC cable
- Wait approx 1 minute
- Bring the line to the center of the oscilloscope’s reticle
- Give the proper focus to the signal line
- Start using the oscilloscope.
1. Once the oscilloscope is turned on, the following parameters must be adjusted: the first thing we have to do is set channel selector 1, in GND-Raw, the following is to regulate the intensity of “Beam” and this is controlled using of intensity adjustment.
2. The rotation “HAZ” must also be adjusted; for this, we must use a precision screwdriver and position ourselves in the beam adjustment screw and then turn it until the line of the screen is entirely horizontal.
- Then connect the channel probe to the channel to be used, then place the indicated terminal (the red one) to the reference output of the oscilloscope, and the black terminal is placed on the ground terminal physical.
- Then you can see how moving the excellent adjustment voltage gauge knob; you can vary the voltage to calibrate it.
- Now using the Volt / Div knob (Volt / Division), this allows us to vary, the square wave signal that enters the channel that is being used, where it can be adjusted, moving Time / Division, it allows us to move the signal on the X-axis.
- Now changing the excellent voltage adjustment knob allows us to see the signal on the Y-axis, and with it to position it in the reference we need or want to put it, this will make it easier for us to take the measurements we want to obtain.
- Adjusting the Time / Division knob, this allows us to move the square signal on the X-axis, to obtain an entire period on the screen to get the time.
