No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

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, ...

[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 ...

[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 ...

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 ...

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 ...
