set up
I set up the oscilloscope with a BNC cable to ch1 connecting to the low output of the generator. Generator producing sine waves at ~50 Hz. Set on DC coupling.
ch1 positioned at v=0. Trigger set at v=0, slope-rising.
Measurements
Measurement- Voltage with original wave
1. using the grid to measure amplitude of the wave I get ~4.4 volts. 2. using the cursor mode I find an amplitude of ~4.64 volts. 3. Using the measure control I again find an amplitude of ~4.64 volts.
REPEATS:making voltage measurements using the measure and cursor controls for waves of different applitudes and 20 and 30 hz. 1. 20hz wave, I find 2.72 volts after adjusting the amplitude. 2. 30 hz with another adjusted amplitude I find 1.36 volts as the amplitude.
Measurements- frequency - original wave (f=1/T)
1. Grid- I find period of ~20ms and so for frequency I find ~50hz 2. Cursor- I find a frequency of ~50Hz 3. Measure control- I find a frequency of ~49.50 Hz
REPEATS:making frequency measurements using the measure and cursor controls for waves of 2.4v applitudes and 30 hz.
1. Cursor- 30.6 Hz 2. Measure control- I find 30.6 Hz
* Trying these functions for different types of waveforms (square wave, etc) to measure frequency and amplitude the oscilloscope seems to do so properly.*
Triggering
A) What does triggering on the rising edge mean? - this means that the trigger is set at a specified voltage on the oscilloscope,and when the waveform reaches that value and is increasing, event is registered.
