On the nRF51, LO leakage was measured when in receive mode.
For 2402~2480mhz, LO leakage was measured at approximately 2745~2836mhz.
The nRF52 does not measure LO leakage.
I can't measure at 4.8ghz either, what should I measure?

Hi,
I am discussing this internally with a few experts and will get back to you as soon as we get a solid conclusion.

I'm using nRF52810 and I'll give you the marking code.

I couldn't find any LO leakage frequency for the nRF52 no matter how much I searched.
Please give me an answer as soon as possible.

Hi,
If you want to measure / look for LO leakage on nRF52 series you need to measure at f_RF-1MHz for BLE1M and f_RF-2MHz for BLE2M

I'm using the example file radio_test.
You mean set "Start RX carrier" and set the channel to 40 (2440Mhz) and the data rate to 1Mbit.
Then the LO leakge is 2439Mhz?
I've tried this and I can't measure LO leakage at all.
I have alerted this internally and will get back to you.

When can you let me know?
Hi,
Please note that expected power level on the LO leakage is very low, around -90 to -100 dBm, maybe? So to measure this you need to reduce input attenuation of the spectrum analyzer to 0 dB and also set RBW to a low value to see the power above the noise level. Hope this helps.
