Application note entitled “Measuring Return Loss with an oscilloscope and a Return Loss Bridge (RLB)” has been completely re-written. We expanded and made corrections to this application note. There existed some confusion as to the definition of “return loss” particularly whether it is a positive or negative quantity. Also improved is the step-by-step procedure on […]
For HF measurements, a 50-100 MHZ scope will work very well. For two meter measurements a 200MHz scope is needed. We recommend portable scopes. They are simple and reliable and lower cost than bench top scopes. There are still some CRT scopes available new, but most manufacturers now produce only DSO (Digital Storage Oscilloscopes). While […]
