    How accurate is pulse width as a measure of response time for a pin photodiode?

    the pulse width was measured by the people who installed it. They used a black box kind of thing and didn't reveal what it is.

    How accurate is pulse width as a measure of response time for a pin photodiode?

    hi Bobby, thank you 4 your interest. the link gives me a rise time of 0.35ns.Which seems not to create problems of broadening.But when we try to measure a 10ns pulse using this s5973, it is giving a broader pulse of 20ns. We did ensure the following: 1)1 Ghz oscilloscope 2)50 ohms coaxial...

    How accurate is pulse width as a measure of response time for a pin photodiode?

    For a pin photodiode, risetime=bandwidth/0.35 i get ~3ns for s5973 will it be affecting the measurement of 10ns laser pulse? How can i reduce the rise time?
