What is the highest frequency that can be measured by CRO?
100MHz scope can measure anyhing upto 100MHz precisely.
Which value of voltage can be measured by using CRO?
(a) Voltage Measurement using CRO : Both d.c and a.c can be measured on CRO. The CRO will be switched on and a horizontal line is obtained using the internal sweep. The unknown d.c voltage is applied to the vertical input terminals placing the input switch to d.c mode.
How many volts can an oscilloscope measure?
400V

What is the maximum frequency a oscilloscope can measure?
100 MHz
System bandwidth determines an oscilloscope’s fundamental ability to measure an analog signal – the maximum frequency range that it can accurately measure. ∎ Entry level scopes will often have a maximum bandwidth of 100 MHz. They can accurately (within 2%) show the amplitudes of sine-wave signals up to 20 MHz.

How is voltage and current measured in CRO?
Current Measurement with CRO: Resistor measures the voltage across the points and then substituting the value of voltage and resistance in Ohm’s law and calculates the value of electrical current. Another easy way to measure current is to use a clamp-on current probe with an oscilloscope.
How the peak voltage is measured using CRO?
To determine peak voltage from an oscilloscope trace, the maximum vertical deviation of the trace from the centre line is measured from the screen. This number of divisions is multiplied by the Y gain from the oscilloscope controls.
How do you find the maximum voltage on an oscilloscope?
What is maximum and minimum voltage that can be read by your oscilloscope?
The maximum voltage is ±300V, period. It doesn’t matter what the settings on the scope are, or whether the voltage is AC or DC. Any voltage less than that will not damage the scope, but what you see on the display may or may not be useful, depending on the settings.
How are D.C and A.C voltages measured?
Both d.c and a.c can be measured on CRO. The CRO will be switched on and a horizontal line is obtained using the internal sweep. The unknown d.c voltage is applied to the vertical input terminals placing the input switch to d.c mode.
How are voltage and current measured in Cro?
Measurement of current is an indirect method. The unknown current is allowed to flow through a known value of resistance R. The voltage developed across this resistance is applied to the vertical deflection plates of CRO. The displacement obtained is measured and the voltage drop across the known value of resistance is estimated.
How is the peak of an unknown voltage measured?
This length I multiplied by the deflection factor gives the peak to peak voltage of the applied voltage. 1/2 deflection factor gives the peak amplitude of the unknown voltage. Measurement of current is an indirect method. The unknown current is allowed to flow through a known value of resistance R.
How is the magnitude of alternating voltage measured?
To measure the magnitude of alternating voltage, the CRO is switched on and the horizontal line is obtained. The unknown voltage is applied to the vertical deflecting plates. Now the sweep is withdrawn. A vertical line is displayed by the CRO. The length of this line is measured using the scale marking on the graticule.
