AM Gain Calibration
Description
This calibration adjusts the gain of the AM circuitry to provide a 10 dB drop for a 1 V input signal. First a
power level is set and a one-volt signal is connected to the input. AM is enabled and the AM DACs are
adjusted for an exact 10 dB drop. The resulting DAC value is stored as a calibration array.
Required Test Equipment
• Agilent E4418B E-Series power meter
• Agilent E9304A E-Series power sensor
• Agilent 33120A function generator
• Agilent 3458A Option 002 digital multimeter
