cheap spectrum analyzer

[vea45]

Hi,

I need to check the emission of my custom nrf52832 board design and I need an spectrum analyzer... To see if my design would pass the regulations and tests.

I was looking for a cheap spectrum analyzer but I can't find opinions or recomendations for one of those.

So I want to ask for any recomendations for a cheap spectrum analyzer and opinions,

thank you!

To check if your custom board (nrf52832) will pass the regulatory tests, you will need to check the harmonics and RX LO.

A spectrum analyzer will therefore need to cover as many of the following frequencies:

For the harmonics, the following frequencies will typically be of interest (center frequency): 4.88 GHz, 7.32 GHz, 9.77 GHz, 12.2 GHz.

For RX LO, RX LO and 2*RX LO (4.88 GHz) need to be checked.

In addition, it can also be nice to be able to measure the output power from the chip.

From what I can see, it looks like Triarchy has some cheaper spectrum analyzers. I haven't tested them, so I don't know anything about them other than their specifications.
