Re: Evaluating RF filters?

That is exactly what I am planning on doing!

in fact, I just now got mine working, but haven't looked at any filters yet.

You could use a broad band noise generator, but I don't think it would work as well.

I am using a RSP1A.

Sweep Control and Input Panels Missing

I received my SPR1A this morning, and have been playing with both SDRuno and SAS. But since my SMA adapters have not arrived I am limited at what I can see with just a wire stuck in the input. However, with the SAS the Sweep Control and Input Control panels are missing. Is this because I am using a ...

Windowing Loss---not really

Hello, all! I just joined this forum. Today I ordered an RSP-1a and downloaded both the spectrum analyzer and SDRuno software. Of course, I can't do anything with it yet. I have been a ham for 50 years next month, and have always been disappointed at the poor quality of affordable test equipment for...
