nRF52832 RF Test continuous signal for modulation test

Hi,

We have a product that uses nRF52832, we are trying to get the FCC Certification. We are using the RF test example to setup the DUT.

We are able to get the signals from the test unit now we would like to test for continuous modulation. 

How to set the device for continuous modulation. 

Note that now we are getting signal till 99ms

Regards,
