Unformatted text preview: (SNR) of 10? The data you need for this calculation can be found in the data sheet on the class web site. (Hint: use Fig. 1 to get the responsitivity and Fig. 7 to get the noise current.) (b) A 931A photomultiplier is connected to a coax cable terminated with a 50 Ohm load for measurement of a continuous laser beam modulated at 100 MHz. The light level is such that there is a 0.5 volt signal on the scope. What is the SNR, assuming same conditions as 2(a)? Is the detector fast enough for the job?...
