RF measurements

[Shalom Gerbi]

Hi 
We're currently utilizing MuRata - MBN52832 Data for BLE and NFC purposes.
We're looking to incorporate testing into our production process to measure various RF BLE signal parameters, including transmission power, sensitivity, PER, and BER .
I've come across some RF testing documentation, but I'm having trouble understanding how to perform the tests described.

In our design, we have an MCU that communicates with the Murata module via UART.

Hi there,

What exactly regarding testing do you have questions about?

Is it how to connect the spectrum analyzer to your board?

What development environment are you using, nRF5SDK or nRF Connect SDK?

**I'm not asking how to use measuring equipment.
I'm currently looking into configuring the test mode for the nRF5SDK is there any guidance on the test mode ?
I am also interested: it's possible to conduct the test using NRF tools with a JTAG connection?
I'm interested in performing RF transmission and sensitivity tests.
Could you please provide guidance on how to enter the ASIC into this test mode?

Hi there,

The nRF52 itself doesn't have a preprogrammed test mode, you have to flash a fw that performs the tests that you want to do. In our nRF5SDK we have 2 relevant test samples:

1. Radio test
2. DTM

The DTM sample tests the radio at the physical level. The Radio test is more configurable, and is probably what you're looking for. 

You can not perform a radio test with a J-link, but you use the J-link debugger to flash the device with the test fw.
