This will trigger on voltage from Channel A. I am going to go ahead and turn on my trigger. I am going to insert a second y-axis and add my Channel B Voltage Sensor. I am going to begin by adding Channel A to my left axis. So let's go ahead and get our Scope set up.
Once your signal generator is set up, we can now go ahead and pin that to our screen, and open up a full-screen Scope beside it. We are going to start our initial frequency at 1000 Hz, our final frequency is going to be at 70000 Hz, over a duration of 25 seconds, in steps of 1 Hz. We are going to be using an amplitude of 3 V. So let's go and turn on the single sweep. I am going to create a single sweep sine wave that's going to be looking at a range of frequencies across the circuit, hoping to find the resonating frequency for the LRC setup somewhere approximately in the middle of my time range. So I am going to click on my Signal Generator, and I will be using Output 1. I am now ready to go set up my signal generator. So I am going to add my two Voltage Sensors. I can do that by clicking on the channel, typing the first few letters of the sensor, and then confirming it with the Enter button. I am going to begin by going to my Hardware Setup and adding my two Voltage Sensors. Now let's take a look PASCO Capstone and getting set up inside of our software. And my signal generator is attached across the entire circuit. In Channel B, I have a Voltage Sensor measuring the voltage across my second resistor. Connected to my 850 interface, in Channel A I have a Voltage Sensor measuring the voltage across the entire circuit. On the circuit board I am going to be using the first inductor component, the first capacitor component, and the second resistor component. I am going to be using the UI-5210 circuit board. Let's begin by taking a look at our LRC circuit setup.
In this video, we are going to take a look at an LRC setup with PASCO Capstone and the 850 Universal Interface.
See these PASCO Capstone features in action as we use the 850 Universal Interface's output to drive an LRC circuit through a range of frequencies in search of resonance: - Signal Generator with a frequency sweep - Fast Monitor Mode - Scope display - FFT display Update Note: Capstone v1.1.1 added new Peak Amplitude and Frequency 'sensors' to the 850 Signal Generator output that allow for even more direct and accurate determination of the LRC resonant frequency than is demonstrated in this video (though this approach still works). See these PASCO Capstone features in action as we use the 850 Universal Interfaces output to drive an LRC circuit through a range of frequencies in search of resonanceSignal G. The Digital Function Generator outputs waveforms that include DC as well as sine, square, triangle, positive and negative ramps.
