MEASUREMENT UNCERTAINTY
Clock Rate Pulse Width (Eye Width)
Pulse Generator Frequency Accuracy:
8133A: 1% of setting
Oscilloscope Horizontal Accuracy:
54845B: ±[((0.007%) (∆t)+(full scale/(2x memory
depth))+30 ps] ≅ 30 ps
Oscilloscope Display Resolution: 54845B: ±5 ps
Setting: 125 MHz + 2% = 127.5 MHz
250 MHz + 2% = 255 MHz
Pulse Width setting: 1.43 ns
PWmax(worst case) = 1.43 ns+30 ps+5 ps = 1.465 ns
