Low maximum Tx output power

I'm using the driver from NI for AD9361. The problem is that the maximum Tx output power is -15 dBm.

 

The device operates in the test mode (registers 0x3f4 = 0x3, 0x3f5 = 0x0, 0x3f6 = 0).

Maximum power output when register 0x73 = 0x4b and register 0x74 = 0;

If I set both registers to zero, the output power is very low. What could be the problem?
