Other Parts Discussed in Thread: CC2541,
Hi, CC2541 experts,
I'm trying to measure the CC2541 TX power level by using CC2540DK and CC2541EMK.
Even CC2541 max TX power is notified as 0dBm, actual max measurement was about -4dBm. 4dB lower than the spec.
I did control TX power by HCI command through RS232 I/F. And verified TX power level is being changed by HCI command.
The measurement was done by Advantest's spectrum analyzer R3267. Other BLE tool like Tescom's TC-3000c
also shows the same result.
I think CC2541EMK should be most optimized sample PCB to check CC2541 RF performance.
What would be the problem ? Anybody could help this ?
