Question

please help with questions 1-4 not sure if i did those right. thank you!

Oscilliscope Screen 8 6 4 2 Voltage (V) -2 -4 -6 -8 Time (ns) -5 -4 -3 -2 -1 0 1 2 3 4 5 square wave triangle wave 20 1. How many seconds does it take the trace to go across 1/2 the screen at the 1 ms/div setting? 1 ms x 6dio 3 MIS dy 2. Which knob controls the amplitude of the signal generator? Which 2 controls do you use to zero the trace? The output leven knob controls the amplitude of the generator. The Channer & Position knob zero the trace. 3. How accurate is the signal generator frequency? Use statistics to compare the output of the frequency generator with the value you measure on the oscilloscope screen. The signal is Pretty accurate with the Channel 1 wave. 4. List 1 source of random error and I source of systematic error? Be very specific. 1 Ransomi I systematic?

Answer 1

For part(1)  total div is 10 not 12 so 1/2 of screen is 5 div hence

Time = 5ms

For part 4 source of random.error can be any disturbance about which we are unaware

Systematic error may be due to misuse of instruments like poor initial adjustments

For other part i think your answer is correct
