How to Measure Power Power Measurement
Agilent 8163A/B, 8164A/B, and 8166A/B User’s Guide, Fourth Edition 87
NOTE If you see the screen shown in Figure 46, the zeroing operation has
failed because the Power Meter received light. The most common
reason for zeroing to fail is if:
• a source is connected to the Power Meter’s input connector,
• the fiber connected to the Power Meter’s input connector is
collecting light, or
• the Power Meter receives ambient light because the input connector
is uncovered.
Press Enter and start again at step 1.
4 When the zeroing operation finishes, press the [Close] softkey to
close the menu.
