Signal generator and user interface for adding amplitude noise to selected portions of a test signal

摘要

A signal generator generates amplitude noise on a selected segment of a test signal. A user interface is used for selecting a segment of the test signal and an associated power level for applying amplitude noise at a selected power level to the test signal segment. A signal processing unit compiles the selected power level of the selected segment with the test signal to generate digital data representative of the test signal with selected segments having amplitude noise. A waveform generator receives the digital data and generating a test signal output having amplitude noise at selected segments of the test signal. The method includes the steps of: selecting a segment of the test signal to add amplitude noise; selecting a power level for the amplitude noise; and applying the amplitude noise at the selected power level to the selected segment of the test signal.

1. A method of adding amplitude noise to a test signal comprising the steps of:
a) selecting a segment of the test signal to add amplitude noise, wherein the segment is less than the entirety of the test signal and is selected from at least one from a plurality of packets within the test signal; b) selecting a power level for the amplitude noise; and c) applying the amplitude noise at the selected power level to the selected segment of the test signal with steps a), b) and c) being implemented using a signal generator having a user interface; the user interface displaying elements for the segments of the test signal and the power level for actuation by a user.
