Test & Measurement World: New test method for advanced wireless systems

Agilent Technologies and Lime Microsystems have described a new method for testing and evaluating advanced wireless systems that pairs Agilent’s test equipment with silicon transceiver technology from Lime. Digital-radio and software-definedradio designers will be able to reduce development time and reduce the design iterations, the two companies claim. They have announced an evaluation platform that is a, “comprehensive, cost-effective method for design validation, even for multistandard radios,” according to Robert Drollinger, marketing manager at Agilent. The offering uses the LMS6002D flexible transceiver from Lime, which is used in end-equipment designs including cellular small cells, software defined radios, public safety and land mobile radios.

The evaluation platform and associated control software allows you to adjust the transceiver’s uplink and downlink frequencies from 300 MHz to 3.8 GHz, with no gaps, and to set the on-chip channel filters to accommodate all cellular standards. With Agilent test equipment and the transceiver from Lime, you can generate digital IQ signals using a pattern generator, convert these signals to RF, and analyse the RF signals with Agilent’s Vector Signal Analyser software on an Agilent Spectrum Analyser or wideband oscilloscope. This setup is supported by software tools (including Agilent’s Signal Studio), coupled with the Lime user interface, for optimising the RF parameters on a given standard or frequency band.
