The following graphs may also be used to compute errors for Period Measurements. To find the Period error (∆P), calculate the frequency of the
input signal ( ) and find the frequency error (∆F) from the chart. Then, calculate the period error as:
Measurement Specifications
Frequency, Period
Channel 1 and 2 Range: 0.1 Hz to 225 MHz 4.44 ns to 10 s
Channel 3 Range:
Option 030 100 MHz to 3 GHz 0.33 ns to 10 ns
Option 050 200 MHz to 5 GHz 0.2 ns to 5 ns
Option 124 200 MHz to 12.4 GHz 80 ps to 5 ns
