CC1310: The actual power value is less than the configured power value

Part Number: CC1310

Hi team，

The customer used his own company's CC1310 module. When he used SmartRF Studio 7 to connect the CC1310 module, he set the power to 15db at 433MHZ. The actual test found that the power was similar to the expected value, but when the burning program was run alone, it was found that the set 15db power was less. 1db, all configurations are the same as before, and the same CC1310 module has not changed. The rfPacketTx routine is used. I searched the forum and modified the configuration as，but still doesn't work，what is the reason for this and what should I do?:

#ifndef CCFG_FORCE_VDDR_HH
#define CCFG_FORCE_VDDR_HH 0x0 // Use default VDDR trim
#define CCFG_FORCE_VDDR_HH 0x1 // Force VDDR voltage to the factory HH setting (FCFG1..VDDR_TRIM_HH)

Thanks & Best regards,

Yolande

    Hi,

    For the same RF output power settings used in SmartRF studio and in the SDK should give the exact same output power results.

    Can you measure the conducted output power measurements with a static unmodulated Tx carrier as well ?
