Spectrum analyzers that use digital-receiver architectures hold the most promise for the wideband low-noise measurements that you must make when developing third-generation wireless products. For many ...

If you think that S/H circuits needn't precede the flash ADCs within modern RF spectrum analyzers, you have another think coming. Even when the ADC in a receiver or spectrum analyzer isn't at the very ...

There are many ways to look at the world, and many ways to look at electronic signals. Many fundamental instruments, such as voltmeters and oscilloscopes, use a time-oriented approach. They provide ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...
