Try to use the Radio test sample in stead, it will let you control both the devices and also works well for testing unmodulated single channel.

[quote user=""]Note: The measurement was made by connecting the cable directly to the antenna output, at the point marked in red on the electrical diagram.[/quote]

Also do you know the loss in the cable you are using ? Should not be that much as you are seeing but for accuracy of the measurement test setup it can be good to know.

Note 2: Using the DTM application, I set the Nrf52833 output to 0dBm.
