4. Block Diagram
5. Operating Procedures
- Adjust the voltage grid of the oscilloscope to 10mV/div and set the input impedance of the oscilloscope to 50Ω;
- Connect the output of the detector to the input of the oscilloscope with a coaxial cable;
- Ensure that the power received by the detector is within the saturation power, and then turn on the light source to be measured and align it with the photosensitive area;
- Observe the waveform of the oscilloscope.
Note: We use a load resistor R to convert the photocurrent I to a voltage V for viewing on an oscilloscope: V = I x R
Load resistance affects response speed, and for maximum bandwidth we recommend using a 50 ohm coaxial cable with a 50 ohm terminating resistor at the other end of the cable for impedance matching. If bandwidth is not important, the amount of voltage in a given light can be increased by gaining the load resistor. The length of the coaxial cable can have a profound effect on the response, so it is recommended to keep the cable as short as possible.
