Introduction In a previous post, I discussed how to use the Friis equation to determine the free space loss and receive level between a transmitter and receiver (Ref.1). Let’s consider an example that I saw in a recent sailing forum. The discussion was around the range of a typical marine VHF transmitter using a quality […]
Introduction EPIRB or Emergency Position Indicating Radio Beacon Station is an emergency transmitting device that blue water sailors or explorers can use in case of distress. They have proven their worth over the years and are absolutely essential for anyone wanting to wander off the grid (Ref.1). At least 2000 people have been saved every […]
As we ease CV19 restrictions in Toronto, it’s time to get outside and enjoy the summer. Today I decided to walk in nature or at least in the closest park. As I walk on the grass and earth, I can almost feel the tension of the past few months draining from my body. What a […]
In the previous post I showed how we can create an AM Modulator with ScicosLab/Scicos. In this post we can use this file to create a .CSV file that can be used to drive an Arbitrary Waveform Generator so it can test equipment in our lab as required. Traditionally Function Generators only produced Sine, Square […]
Function Generators typically produce Sine, Square, Triangle, Saw Tooth and DC signals. Many modern instruments include an AWG or Arbitrary Waveform Generator signal as an additional selection. This allows you to construct your own custom waveform to meet your testing needs. Typical examples might be a dual/multi tone audio signal to test intermodulation distortion in […]
