• <High Power (2)>, a high power optical output, for example, for use
in tesing Erbium Doped Fiber Amplifiers (EDFAs), you see a screen
similar to Figure 78 on page -137,
• <Low SSE (1)>, a lower power optical output with low Source
Spontaneous Emission (SSE), for example, for use in passive
component test, you see a screen similar to Figure 79 on page -139,
• <Both (master:2)>, where both optical outputs can be enabled but
only the output of the high power optical output can be regulated,
and
• <Both (master:1)>, where both optical outputs can be enabled but
only the output of the low SSE optical output can be regulated.
• Press Enter.
How to Measure the Reference
18 Press [Reference].
The PACT Reference Screen, as shown in Figure 179 on page -292,
appears. The number of samples that each Power Meter will record and
the output laser power are displayed If <Continuous> was selected as the
sweep [Method], the sweep speed, [VSweep], is displayed.
NOTE
If [Step] does not divide exactly into the difference between [λ Stop]
and [
λ Start], the parameters are automatically corrected to meet the
constraints of PACT.
