https://devzone.nordicsemi.com/f/nordic-q-a/16970/cheap-spectrum-analyzerHi, 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&#39;t find opinions or recomendationsen-USTelligent Community 13Thu, 13 Oct 2016 10:09:04 GMThttps://devzone.nordicsemi.com/thread/65094?ContentTypeID=1Thu, 13 Oct 2016 10:09:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d094768-e1b9-416a-9320-319f356f466bvea45<p>Thank you! This info is very useful!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65093?ContentTypeID=1Tue, 11 Oct 2016 07:11:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9ed26d2e-547d-41e5-b749-9310176d9e26FormerMember<p>To check if your custom board (nrf52832) will pass the regulatory tests, you will need to check the harmonics and RX LO.</p> <p>A spectrum analyzer will therefore need to cover as many of the following frequencies:</p> <p>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.</p> <p>For RX LO, RX LO and 2*RX LO (4.88 GHz) need to be checked.</p> <p>In addition, it can also be nice to be able to measure the output power from the chip.</p> <p>From what I can see, it looks like Triarchy has some cheaper spectrum analyzers. I haven&#39;t tested them, so I don&#39;t know anything about them other than their specifications.</p><div style="clear:both;"></div>
