and calibration factors.
A frequency in the range of 0.001 MHz to 999.999 GHz can be entered.
A calibration factor in the range of 1% to 150% can be entered.
The following rules apply to naming sensor calibration tables:
• The name must consist of no more than 12 characters.
• All characters must be upper or lower case alphabetic characters or

Predefined sensor calibration factor table stored in power meter is not applicable for
Agilent N8480 Series power sensors with Option CFT. Therefore, users are required to
create a new sensor calibration table for the sensors when a sensor calibration table is
needed.
