Power Tests
The procedures in this section show how to measure the Maximum Output
Power, Power Linearity, Power Flatness versus Wavelength, and Power
Stability.
Maximum Output Power
For definition, see “Maximum output power” on page 40.
Make sure the instruments have warmed up before starting the
measurement.
Measurement Principle
The TLS' output power is set to excessive power (indicated on the display
by "ExP") to get the highest achievable power. For each wavelength within
the specified wavelength range, the actual output power is measured and
compared against (wavelength-dependent) test limits.
Figure 23 Maximum Output Power.
•Absolute power accuracy is not specified.
• The result of the measurement is greatly influenced by the quality and
matching of the interconnections used.
