Power Level Accuracy, High Power Calibration
Description
This calibration adjusts both power flatness and power level accuracy. First the power flatness and power
level accuracy calibration constants are initialized to zero. Then power flatness is measured with a power
meter and corrected with the internal attenuator set to 0 dB. The power meter measures the RF output over
the +13 to
−
55 dBm dynamic range and calibration constants are set to optimize power level accuracy over
this range.
Required Test Equipment
• Agilent E4418B E-Series power meter
• Agilent E9304A E-Series power sensor
Procedure
1. Connect the equipment as shown below.
2. Preset all of the equipment.
3. Follow the instructions as they appear on the controller’s display.
