Last month, I talked about how to get started with mBed and ARM processors using a very inexpensive development board. I wanted to revisit mBed, though, and show something with a little more substa… ...

[Armeen] — a summer intern at Opal Kelly — did a very interesting open source FPGA-based signal generator using a Xilinx FPGA, and a SYZYGY-compliant digital to analog converter.

To test an RF system, you need to apply a signal. The type of signal you need depends on the device and operating conditions—you may start out with clean signals in initial design phase, graduate to ...

Some tracking generators have a limited frequency sweep as compared with their mating spectrum analyzer, so you need to know any frequency limitations in advance. For this example, I'll use the new ...
