BLE Occupied bandwidth

[Tao]

Hi Nordic's experts

We got a RF problem in certification test, attached picture is the measured occupied bandwidth, the value of OBW is 1.73MHz, but the guy in the lab told us that this measured value is a little bigger than they measured before, the normal range is 0.8 ~ 1.2MHz, so can you help check what wrong with our board? Do I need to tune the RF circuit?

Thanks

This will be an application specific issue, so I would recommend you to move this question over to Nordic tech support here: www.nordicsemi.com/.../Support

If you could upload the design schematic and layout to the case you open there and also add information on what kind of payload you send and describe the test setup as well, that should make it easier for us to help you out.
