The shield makes the DDS Module easy to configure ( through software ) and to control (through familiar, everyday interfaces such as Keypads, Displays and Rotary Encoders). I am going to post a quick review on this device now that I have had a chance to use it. Fixed bandwidth spectrum analyzer sweep with about 4KHz bandwidth. Recently I purchased a Mini 60 antenna analyzer. , the “network”) Measures power level differences between the input and output of the DUT Expresses power level differences logarithmically, in dB or dBm Applications RF filters Antenna analysis and tuning Crystal selection for crystal filters. com: antenna analyzer kit. VSWR measurements are presented on a TFT LCD touch display with IL9341. It is in the form of a docking board on the STM32F746 Discovery board. ) Shield PCB for the arduino. I ended up modifying slightly an Arduino sketch that was written for the 9851, putting the AD9850 on a UNO prototype shield, and testing it in single frequency mode. AD9851 DDS board. Build a HF antenna analyser for £50! Posted by Matt under Antenna Analyser [3] Comments Every amateur radio operator should measure the SWR (Standing Wave Ratio) of their antennas – the SWR is an indication of how much power is being sent to the antenna (the forward power) and how much is being reflected back from the antenna if it is. In the long run and for some projects a wanted something simpler (not smaller), and iron out the mess with the different pinouts/functions per pin etc (personal view of course).
