2.2 Comparison of VSG to analog signal generator 2.2.1 Analog Signal Generator Overview Since there are separate amplifiers, the amplitude of the tone would vary andĬould be hard to control the phase with respect to each tone. The signals would be combined inįree space. Generators, multiply amplifiers, and multiple antennas. Modulated signals, including cellular, wireless LAN, Bluetooth, GNSS, and militaryĪnd a third, more cumbersome, way to generate multiple signals is to have multiple signal VSGs are useful for simulating a wide variety of digitally Phase sets, deliver accurate repeatable multi-tone signals and is easily configurable by Signal generators to create multi-tone signals. Generators with one vector signal generator (VSG). Antenna resonant frequency measurement and testingĪn alternate way to generate multiple signals is to replace each independent signal.A vector signal generator, VSG, is the primary hardware in a multi-tone generator system it can be used in almost every RF and communication application, including the following below: Two-Tone and multi-tone signals are used in the communications industry to test for nonlinear distortion for amplifiers, receivers, etc. Multi-tone tests are part of many test specifications used to test the frequency response of a device and measure intermodulation distortion. Therefore custom multi-toned sets need to be created. Standard multi-tone signals have evenly-spaced tones with equal amplitude this, however, does not represent real-world test conditions. This allows an audio signal to be tested over long distances, such as the internet or mobile phone. Multi-tones can be used in an open-loop audio test where the analyzer does not have to sync up with the generator.

One area in which multi-tones are used is modern audio measurements to test consumers & professional audio devices, broadband devices, and internet audio.
1.2 Where are multi-tones used, and who is using them? In the time domain, the multiply signals or tones will be a composite signal in which each of the tones will add or cancel to make a composite signal. In the spectrum domain, the multi-tone or RF energy will be present at a unique frequency. Multi-tone signals are composed of multiply single sine waves or tones with a unique amplitude, phase, and frequency. Resources, as well as faster time-to-market for new and enhanced products. Benefits can also include more efficient use of finite financial and human Method also improves equipment efficiency, offers greater flexibility to truly test theĮquipment (EUT) under real world threat conditions, and can be fully compliant to
Implemented to increase the speed of immunity testing, it has been found that this While the multi-tone methodology was initially Knowledge Center > Application Notes Multi-Tone: Testing, Theory and Practice
