Linearity Test
Shahab Khan and Peter Torres

2. Objective
A linearity test is performed to determine if there is a direct response from the cells and PMT
To rule out the possibility of light leakage, light saturation, or any other problems
By changing the input light incident upon the cells, we should see a linear output response

3. Procedure Used discrete pulsed LED with settings:
f = 100 Hz, Amplitude = {8,10,12,14,16}V
Observed output current from ammeter as input amplitude was varied
Took 500 measurements for each LED input
Repeated procedure for PMT Voltage 1400, 1500, 1600, 1700

4. Results
