While signal integrity is not a critical issue at lower frequencies, at higher frequencies (in the range of 2-10 GHz) it plays a vital role. When it comes to high-speed boards, designers need to pay attention to both analog and digital aspects of the signal. ... Frequency response: A VNA includes many receivers, each having slightly varying ...So in your VNA: What it does is measure the response of your network over a bit of the spectrum at a time. It sends out RF signals at some frequency and analyzes the reflections. A tuneable oscillator is fed into a mixer with the incoming reflections. This down-converts the reflections from their RF frequency to a fixed IF.Delay is calculated by the VNA from the change in S21 phase divided by the change in frequency. Delay variation or dispersion causes higher frequency elements of a digital bitstream to arrive at a different time from lower frequency elements. This stretches out the total bit time and may result in it intruding into the time frame of the next bit.VNAs find use cases extending from IoT to medical and materials science applicationsDownload this article in .PDF format.Vector network analyzers are versatile instruments offering...
