Meeting the Challenge of Multi-standard Wireless Communications Testing
December 16, 2010 9:05 am | CommentsBy Tim Carey, Aeroflex Test Solutions Non-cellular technologies are increasingly being integrated into cellular terminals, and this has generated the need for test systems that comprise a number of different test platforms, which can make system integration both complex and costly. At the same time, there is pressure to increase test speed and, in combination with the proliferation of functional tests associated with the introduction of new standards, this further increases the costs.
Generating Multiple Digitally Modulated Carriers Using an AWG
December 15, 2010 11:11 am | CommentsBy Thomas Dippon, Agilent Technologies When testing wideband RF components and systems, it is necessary to stimulate the device under test (DUT) with a wideband signal that is as close to the “real” signal as possible. For some measurements, wideband noise or a multi-tone signal might be appropriate.
