[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...

[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp ...

Audio Precision has introduced its new APx555 B Series analyzer. According to AP, the second-generation APx555 offers improved sine generator frequency stability, lower system residual distortion, ...

Join the community discussion that is already taking place about this articleUnderstanding Your Signal Analyzer’s “Dynamic Range” Despite having just used the term “dynamic range” in the title myself ...

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 ...

Scopey II is the name used for this project which involves the use of dsPIC to build an oscilloscope and spectrum analyzer. The device is using a BNC jack on the front where everything comes in ...

Today’s RF test instruments are highly complex products and are therefore characterized by a wide variety of specifications. We have presented a three-part series on a wide array of RF instrument ...
