ECET 17700 Insert your name Instruction: Complete all work including insertion of any figures in this Word document, then save as pdf file. Turn in at the assignment area of Brightspace. Due date according to what’s indicated in BS. 05. AC Instruments and Measurements 1. Measure Resistance: Connect the probes: Connect the oscilloscope probes to the circuit under test. Make sure to connect the ground clip to a common ground in the circuit. Select the input channel: On the oscilloscope, select the input channel that corresponds to the probe that is connected to the circuit. Set the voltage scale: Adjust the voltage scale on the oscilloscope so that the waveform is displayed within the limits of the display. 2. Measurement of DC offset: Connect the circuit: Connect the circuit under test to the oscilloscope. Select the waveform: On the oscilloscope, select the waveform that represents the signal you want to measure. Add the DC offset: Use the DC offset control on the oscilloscope to add a DC offset to the waveform. You can use this control to shift the waveform up or down on the display. 3. Series Circuit Measurements Note: units are included in the header row, there should not be units inside each of the cell Table 1: Series Circuit Resistances Resistor Nominal resistance (Ω) Measured resistance (Ω) R1 820 816 R2 1000 987 R3 4700 4689 R T 6520 6492 Table 2: Node Voltages (single-subscript) Node Theoretical voltage (V rms ) Measured voltage (V rms ) Percentage Error (%) V A V B V C V D 1
ECET 17700 Insert your name Insert a picture of the oscilloscope picture you saved from this procedure. Make sure to include all the measured values. At the bottom of the picture, insert caption to describe the measurement. Analysis and Conclusions 1. If the oscilloscope display is too small, only filling ¼ of the display vertically, which control do you adjust? If the oscilloscope display is too small, only filling ¼ of the display vertically, you would adjust the vertical scale control. This control sets the amplitude of the waveform displayed on the oscilloscope screen. By adjusting the vertical scale, you can increase or decrease the size of the waveform to fill more or less of the screen. 2. If the cycles on the oscilloscope display are too crowded together, showing 6 cycles, which control do you adjust? If the cycles on the oscilloscope display are too crowded together, showing 6 cycles, you would adjust the horizontal scale control. This control sets the time base of the waveform displayed on the oscilloscope screen. By adjusting the horizontal scale, you can increase or decrease the time between consecutive cycles, making them more spread out or more crowded together. 3. If the display is rolling and will not display a stable wave, which control do you adjust? If the display is rolling and will not display a stable wave, you would adjust the time base control. This control sets the time base of the waveform displayed on the oscilloscope screen. By adjusting the time base, you can slow down or speed up the waveform, making it display more steadily or rolling continuously. If you are having trouble stabilizing the waveform, you may also need to adjust the trigger level control, which sets the voltage level at which the oscilloscope starts displaying the waveform. 2
