[Shahriar] just recently published a evaluation of a 6.8 GHz network analyzer. You can see the full video — over fifty minutes worth — below the break. The gadget can act as a network analyzer, a spectrum analyzer, a field stamina meter, as well as a signal generator. It can tune in 1 Hz steps down to 9 kHz. before you rush out to buy one, however, be warned. The expense is just under $2,000.
That seems like a lot, however test gear in this frequency variety isn’t cheap. If you truly requirement it, you’d most likely have to pay at least as much for something equivalent.
[Shahriar] had a few problems to report, however general he seemed to like the device. For example, setting the step size as well broad can cause the spectrum analyzer to miss narrow signals.
If your needs are more modest, we’ve covered a much easier (and less expensive) system that goes to 6 GHz. If you requirement even less, an Arduino can do the task with a great bit of help. The Analog discovery 2 likewise has a network analyzer feature, together with other tools at a more inexpensive cost, too. Of course, that’s only great to 10 MHz.
