Rssi measurement with CC2500
I am intending to use the CC2500 module as a receiver to measure the RSSI of 2.4 GHz RF signals. My question is if the signal is modulated at 3000 kbps while the maximum data rate of CC2500 is 500 kbps, will the module still be able to measure the RSSI level accurately ?
No, the CC2500 will only receive part of the signal and hence the RSSI value will not be correct.

I would like to relaunch my question about the chip CC2500. I have an emitter that emit signals at 2.4 GHz, the duration of each emission is 400 microsecond. The goal is to measure the RSSI of these signals arriving at the receiver.
"...the CC2500 will only receive part of the signal and hence the RSSI value will not be correct.", did you mean the emitter has to emit the signal continuously for a certain duration in order that the chip CC2500 is able to measure the RSSI ?
If it is the case, would the CC2500 chip be able to measure the RSSI of signals emitted by the emitter in 2.4 GHz channel while the duration of emission is 400 microsecond? Or is there another condition for the chip to measure the RSSI correctly?
You want to measure RSSI on a 3000kbps signal and the CC2500 has a RX bandwidth of 500kHz. I couldn't see any information about deviation. If you look at this in the frequency domain the signal you want to measure on has a much larger bandwidth than CC2500 is able to receive. With a large deviation the two frequency tops in a FSK spectrum could end up on both sides of the RX bandwidth of CC2500 and a lot of the signal energy will not be received, hence the RSSI value will be off.
Thank you for your responses.
