CC2340R5: measure CC2340 tx power scenario.

Part Number: CC2340R5

Tool/software:

Hi Ti experts.
We see two value in the tx power current of the CC2340R5 datasheet,
How to use the program to control dcdc off and system bus off?
2. If the modulated signal produced by smart rf studio 8 is measured using LP, it is 17.6mA. Does this correspond to the situation of DCDC OFF and system buss off?

  • Hi Weli,

    1. DCDC can be controlled via the latest version of SmartRF Studio 8. The 3 components of system bus has be turned off individually. See the Technical Reference Manual.

    2. 17.6mA is correct and does correspond to DCDC and system bus off because the launchpad operates at 3.3V while the datasheet results are validated using 3V the lower current draw is expected. When voltage supply increases the current draw decreases because the device is trying to maintain constant power consumption.

    Best regards,

    Bun
