October 17, 2011. Arbitrary Resources S.L., an R&D and consulting company serving the test and measurement industry, has announced ArbIQ, a wireless signal creation software application for a wide range of arbitrary waveform generators (AWGs) from multiple vendors. ArbIQ simplifies the work of design and manufacturing engineers who need real-world stimulus to apply to the latest generation of wireless devices implementing SDR (software defined radio) architectures.
ArbIQ allows creating digitally modulated signals in a variety of situations. It supports the generation of baseband (IQ) and IF/RF signals in analog or digital format. It can create ideal or distorted dissimilar multicarrier signals where users can define all the modulation parameters and distortions independently for each carrier. The ArbIQ package supports multiple general-purpose modulation formats such as QPSK, QAM, or FSK, and, at the same time, it supports channel-coded signals for applications such as mobile telephony (UMTS and CDMAOne), wireless networks (802.11b, Zigbee, and Bluetooth), or digital television (8/16VSB and DVB-C). It includes WiMedia and DVB-T sample signals, among others, for basic test and educational purposes.
ArbIQ’s flexibility and openness make possible targeting virtually any AWG in the market, raging from value instruments up to state-of-the-art AWGs with sampling rates beyond 10GS/s, no matter their vertical resolution, analog bandwidth, or waveform memory size. Standard features in ArbIQ include support for a variety of modulation schemes.
“ArbIQ adds to any AWG the capability of generating complex and accurate digitally modulated multi-carrier signals. Its flexibility allows any user to create any signal to be applied to any point in the signal chain of any transmitter or receiver,” said Joan Mercadé, general manager of Arbitrary Resources, “and it does so while fully exploiting the target AWGs performance in terms of sampling rate, vertical resolution, number of channels and record length. Ease-of-use and usability is a very important aspect so users are isolated from the complex aspects of both the signals and the instruments while offering a very fast signal compilation time.”
