Example 3 - Measuring the P
ower of a Modulated Signal
Figure 6-1. Connecting the Instruments for the Sample Session
Typically, you would connect a component to test between the tunable laser
source and the power meter.
4. Make sure that both instruments are powered up.
Note
Normally you also need to be sure that the instruments are
properly warmed up before using the source, or making any
measurements. In this case, because the measurements are not
critical, it is acceptable to proceed immediately to the next step.
