CC2540 doesn't transmit moudulated output at SmartRF Studio7 v1.6.1.

Other Parts Discussed in Thread: CC2540, CC-DEBUGGER

I had operated CC2540 that was connected to CC-debugger and PC.

Until yesterday, version of SmartRF Stdio7 which I used is v1.3.2.

At "Continuous TX" mode of v1.3.2, frequency = 2440MHz, Tx Power = 0 dBm, and check "modulated", Spectrum analyzer shows modulated wave form.

At "Continuous TX" mode of v1.6.1, frequency = 2440MHz, Tx Power = 0 dBm,Spectrum analyzer shows below  wave form.

Unmodulated: 2439.999 MHz CW

Modulated: 2439.745 MHz CW

I think that modulated pattern is PN9.

Why is not a modulated wave pattern measured?

Next question, at "Packet TX" mode, is the setting value of packet interval is effective ?
