如何使用示波器(How to use oscilloscope) How to use oscilloscope.Txt In the process of appliance maintenance, the use of oscilloscopes is very common. By oscillograph, we can observe the waveform of the circuit under observation, including shape, amplitude, frequency (phase) and phase, and ...
Key Oscilloscope Specifications Some scopes are better than others. These characteristics help define how well you might expect a scope to perform: Bandwidth-- Oscilloscopes are most commonly used to measure waveforms which have a defined frequency. No scope is perfect though: they all have limits ...
test points in your circuit, and measure the voltage, you can calculate the current. Another method is to use a current probe. A current probe connects to an oscilloscope just like a standard probe. Once connected, it will provide automatic unit scaling and readout on the oscilloscope's ...
The frequency of a wave is the number of times per second that a wave repeats its shape. 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 ...
Attenuated oscilloscope probes To minimize capacitive loading on the device under test, most probes use a x10 (also called 10:1) attenuator. This can often be adjusted, or compensated, to improve the frequency response. The following note explains the adjustment technique using two example probes...
On my PCBA design based on i.MX6ULL. the base system is Linux OS. Now we measured the DDR frequency with Oscilloscope and confirmed it's 307MHz. Then we read the register's value of CBCDR, CBCMR and CCM_ANALOG_PFD_528n and got the following value: ...
In this scenario, bandwidth can only help us figure out how to get these details. In terms of bandwidth measurement, we only know that if a sine wave of the same frequency and bandwidth is input, the oscilloscope's amplitude measurement error is 30%. Ⅲ. What's the connection between ban...
The frequency bandwidth of the oscilloscope will affect the test result, usually the standard is 20MHz, or 30MHz (INTEL test requirement), the sampling frequency for digital oscilloscope should be more than twice of the PARD frequency. 2.1.4. Input Resistance : Usually we use 50 Ohm. For ...
