Homing the Variable Attenuator (User Calibration)
Homing the Variable Attenuator (User
Calibration)
The variable attenuator contains mechanical elements used to change
attenuation or output power (self-adjusting modules) levels. It is a good
practice to have the instrument mechanism return to the zero (home)
position to reestablish its relative position on the range of attenuation or
output power levels.
EXFO recommends that you perform the homing procedure when the
homing icon appears on the data display.
To home the attenuator:
1. On the Settings function tab, click the Attenuator tab.
2. Click the User Calibration button.
The attenuator mechanism is moved to the zero (home) position.
