The nRF7002 is a dual-band (2.4 and 5 GHz) Wi-Fi 6 compatible companion IC. It does not have a general-purpose microcontroller built-in. Instead, Nordic intends for you to combine it with another microcontroller, like one of their nRF52 or nRF53-series system on chip (SoC). Nordic and the element14 Community sent me an nRF7002 Development Kit (DK), Evaluation Kit (EK), and some nRF7002 QFNs. I reviewed the nRF70 variants in this video and looked at the various boards. As the thumbnail suggests, I connected the Wi-FI transceiver to a FPC1500 spectrum analyzer.

Spectrum Analyzer Basics | Workbench Wednesdayshttps://www.baldengineer.com/spectrum-analyzer-basics.htmlThu, 17 Oct 2019 02:06:58 +0000https://www.baldengineer.com/?post_type=link&p=7953A spectrum analyzer displays signals in the frequency domain. To use one, you only need to know about four controls: reference level, center frequency, and resolution bandwidth. In this episode, see how to use a spectrum analyzer and determine the transmitting frequency of a device. The example device is my microphone transmitter. It operates around 500 MHz with FM modulation. You’ll see how I step through the spectrum analyzer controls to find the exact frequency. At the end of the episode, I show some advanced measurements you can do with a modern spectrum analyzer. My favorite one is the demodulation.

FPC1500 Review, a Rohde & Schwarz Spectrum Analyzerhttps://www.baldengineer.com/fpc1500-review.htmlWed, 04 Apr 2018 13:00:15 +0000https://www.baldengineer.com/?p=7076Everyone’s first piece of test equipment should be a multimeter. Next is probably a power supply with current limiting. For many engineers, the next step is an oscilloscope. At least those working on digital electronics. Even if you are not working with RF, do not overlook a spectrum analyzer. The Rohde & Schwarz FPC1500 is three instruments in one: a Spectrum Analyzer, RF Signal Source, and a Vector Network Analyzer. In this post, I combine an FPC1500 review with an introduction to these frequency domain tools.
