Abstract

The invention discloses an agile signal power pre-calibration method based on a digital automatic power control circuit, and the method comprises the following steps: 1, setting the digital automaticpower control circuit for achieving the power closed-loop control; and 2, performing power pre-calibration on each frequency point needing frequency agility by using a digital automatic power controlcircuit and adopting a pre-calibration method. By adopting the technical scheme of the invention, the following advantages can be realized: 1, the digital automatic power control circuit is high in power control speed and flexible in data processing; According to the pre-calibration method, power pre-calibration is carried out before frequency agility, and the signal power accuracy is high.

Description

technical field [0001] The invention relates to the field of power control of radio frequency / microwave signal generators, in particular to an agile signal power precalibration method based on a digital automatic power control circuit. Background technique [0002] There are generally two power control techniques used in signal generators, one is automatic power control (ALC), and the other is open-loop control. The advantage of automatic power control technology is high power accuracy, but the control speed is slow; the advantage of open-loop control is fast control speed, but the power accuracy is low, and it is easily affected by the ambient temperature. An agile signal generator is a radio frequency / microwave signal generator whose output signal frequency can be switched quickly, and its frequency switching time is usually short, up to hundreds of nanoseconds. In order to increase the switching speed, the output power of existing agile signal generators is usually contr...
