Other Parts Discussed in Thread: , CC1175
My customer is using a CC1120EMK-420-470 daughterboard to check operation, but it is not outputting at the value they think they have set for the 429MHz frequency. The host microcontroller is not TI.
They are set to 429.25MHz + 0.0018MHz with a register setting that makes the output at 10dBm. However, what they were able to observe on the spectrum analyzer is 377.5 MHz, which is 4 dBm.
(FREQOFF:0x0CD, FREQ:0x6B4CCC, PA_CFG2:0x37)
Is there something wrong with the settings?
Or should we use the parameters set in SmartRF Studio?
(Select CC1120 and open the control panel->change "Carrier Frequency" to 429.25MHz->use Register Export)
If you have any documentation on the proper setup procedure, it would be appreciated if you could share it with us.
