Yep, I understand... Good luck! Sergio On Tue, Feb 21, 2012 at 9:20 PM, Xiaohui Liu wrote: > Hi, > > Thanks for your data. > > I'm just wondering if there is any one else having similar result with > yours before I accept it as my ground truth. 4-5 dB's difference is too > large for my purpose.

Hi, Thanks for your data. I'm just wondering if there is any one else having similar result with yours before I accept it as my ground truth. 4-5 dB's difference is too large for my purpose. Or has anyone got a measurement conforming to the datasheet? On Tue, Feb 21, 2012 at 12:20 PM, Sergio Va

Re: [Tinyos-help] Output power at each power level from 0 to 31 for CC2420

Hi We sold a sma connector to the iMote2 board which was connected directly to the spectrum analyzer, through a good and short cable (I assume < 1dB att @ 2.4GHz). I did not use a vector network analyzer to check the impedance... so the only thing I guess now is that we had to move one smd capaci

Hi, This is what the datasheet says: power vs dBm 3 -25 7 -15 11 -10 15 -7 19 -5 24 -3 27 -1 31 0 Somehow your measurement of those power levels is 4-5 dBm lower than what is shown above. Are you using an attenuator over the antenna or measuring the power some

Re: [Tinyos-help] Output power at each power level from 0 to 31 for CC2420

Hi, this is what I measured one and a half year ago using an iMote2 and a spectrum analyzer, I actually demodulated the signal so you can be sure that the values are quite accurate. However the weird thing is that the mote did not rise to 0dBm, but only to -4dBm. Sorry, I did not remember whether

[Tinyos-help] Output power at each power level from 0 to 31 for CC2420

Hi everyone, Does anyone know what the output powers are at each power level from 0 to 31 for CC2420? The CC2420 datasheet only gives the output power for level 3, 7, 11, 15, 19, 23, 27 and 31. However, the output power for other levels like 2 or 12 are missing. I find some threads such as 1
