In a previous video I have shown how to generate test signals for a VOR radio navigation system for aircraft.. This article will take a look at another radionavigation system, the Instrument Landing system or “ILS” for short. The ILS is used by aircraft around the world every single day. It is designed to guide […]

Video Distribution Amplifier | 10 MHz Reference Distribution
Three Sigma VDA-100 Video Distribution Amplifiers (DA) have been sitting on my shelf for a while. The DAs have been waiting to be repurposed for something useful. When Jackson Labs sent me a custom variant of the FireFly-IIA GPS-Locked double ovenized 10 MHZ reference oscillator, I decided to repurpose one of the VDA-100 as a […]

Tektronix RSA 306 | GPS Receiver and Clock Reference
The Tektronix RSA 306 is a great low-cost USB 3.0 spectrum analyzer for up to 6 GHz in an ultra low-profile format. If paired with the RSA Map function of SignalVu-PC and a GPS receiver, it becomes an extremely powerful tool for interference hunting and signal strength mapping. This article shows a possible way to […]

Lumped-Element Wilkinson Splitter / Combiner Design
This is a supplemental article to two of my videos on my YouTube channel about the theory and design of Wilkinson splitters and combiners. A Wilkinson divider is a specific class of power divider with high isolation between the output ports. This feature is particularly useful when used as a combiner. This article will show […]

VOR NAV Receiver Testing
This video shows how to generate a complex test signal to emulate a ground based radio navigation system for aircraft (VOR). The generated signal can then be used to verify the accuracy of navigational receivers intended to be used with a VOR. Used in this video: LeCroy WS3162, LeCroy HDO4024 and Yaesu FTA-720
