1. ### Uncertainty of an oscilloscope frequency, read from the period

Hi, I am unsure of what uncertainty to get, so here is my full question: I used the CRO for an experiment, and since what I need is frequency, I read the period, so for the uncertainty of the period, it is the smallest division divided by two. So if my uncertainty for period is 0.001s, then what...
2. ### Offset Limits in RIGOL Oscilloscope

Hello, I have a very specific problem and didn't find any way to solve it. My signal is very slow changing at 5V +-100mV When I want to display this signal on my RIGOL Oscilloscope, the problem is, that with AC-mode I don't see those slow changes and in DC-mode the offset range is limited to...
3. ### Using Tektronix Oscilloscope to Measure Phase

Hi guys, I am working on a project that involves measuring the phase angle between two sinusoidal voltages. The circuit under examination is an RL type (the resistor was in series with the inductor), where the phase of voltage across the inductor is measured relative to the voltage input of the...

15. ### Engineering Finding the component values of a RLC circuit

What methods could I utilise to find the individual values of the components - resistor, inductor and capacitor - of a series RLC circuit using an oscilloscope, signal generator and 10 ohm resistor. Where each component can be isolated in order to find the voltage etc. I've already found the...
16. ### Ultrasound NDT (non-destructive testing)

Hi all, I've a question and I hope that I can get some answers here. As what my project has tasked, and what my lecturer had said. He needs me to build a device for NDT Testing. Currently the set up is that I would source for a transducer via olympus coupled with a USB oscilloscope capable...
17. ### Measure high and low impedance

Hi All, I am measuring the impedance response of a piezoelectric component. It has a unique impedance response having a resonance portion (low impedance ~10-30ohmns) and large impedance (100k-200kohmns) within a 2kHz bandwidth. See the webpage for a figure showing the impedance behavior. The...
