چکیده
Wideband AWGs are commonly used for simulating signal scenarios for receiver testing and transmitter upconversion blocks. The wideband AWG's ability to generate arbitrary signals is important in aerospace and defense and emerging communications where a wide range of signal formats are used. Many of these are either proprietary or do not comply with any accepted commercial standard. In addition, the high dynamic range of the wideband AWG makes it possible to simulate the effects of system impairments such as distortion and noise, and to verify overall system integrity under these stresses.

Static Characterization of Arbitrary Waveform Generator based on Modified Multi- sine Fitting and Zero Crossing Detection Algorithms
The static characterization of the output section of the Arbitrary Waveform Generator (AWG) requires that its output signal must be digitalized by Analog to Digital Converter (ADC) with higher linearity and resolution than the device under test. In the literature, the problem of high resolution acquisition is translated to the simpler problem of low resolution and high sampling frequency acquis...
متن کاملLow-Distortion Sinewave Generation Method Using Arbitrary Waveform Generator
This paper describes algorithms for generating a low-distortion single-tone signal, for testing ADCs, using an arbitrary waveform generator (AWG). The AWG consists of DSP (or waveform memory) and DAC, and the nonlinearity of the DAC generates distortion components. We propose here to use DSP algorithms to precompensate for the distortion. The DSP part of the AWG can interleave multiple signals ...

Simplest (and most expensive) approach may be to combine the outputs of N number of separate signal generators through an N-way power divider. Digital sources, such as a direct digital synthesizer (DDS), can also be used to generate multiple tones, although at a more limited total bandwidth and with less output power than separate signal generators. Similarly, a vector signal generator, which i...
