how does a microwave work
Hi, it is actually called equivalent time sampling oscilloscope. For example, Agilent 86100B Infiniium DCA Wide-Bandwidth Oscilloscope which has Bandwidth to 65 GHz optical and 80 GHz electrical. It is impossible to use high sampler at 65GHz and 80GHz (it is very very expensive and it is still not available now). The sampler used is normally about 2-5 Gsample/s (depends on the model).The technology applied: To measure time domain signal, you need to split the signal into 2, 1 as trigger and the other as input. The scope will sample at a few different interval of the input signal and display the result. For this type of scope, normally it will take a few second to show the result...
