Hello this is divya,Can anyone help with this

My problem is i am doing on the msk modulation signal using cc1110 ttc board I have to transmit and receive the data using the msk modulation

RF Parameters i used are frequency-433Mhz,Baud rate -26kBaud,Giving the transmitted power 10dbm getting the register values from smart studio rf 7

in that i am facing the power consumption is not varying it's constant I am not unable to get the spectrum in spectrum and vector analyzer . What should i do to get a spectrum

any suggestions please

Thanks

Unclear what you mean. Could you post a screenshot of what you get?

I think this is the same question as the one here (+) CC1110-CC1111: for MSK transmission - Sub-1 GHz forum - Sub-1 GHz - TI E2E support forums, so I will close this thread.

No, but the original question in that post is for the CC1110 and (433MHz frequency, 26kBaud Data Rate, 10dBm TX Power, 843kHz RX Filter Bandwidth), so I assume that this post is related to that one, and it will be handled there. Someone will be assigned to that thread.

hello thanks for the response
Now i will get the spectrum of msk signal like this

i am able to transmission the signal but not able to receive the data using teraterm it takes time to configure while we put the break point
the register values i used are

FSCTRL1 = 0x06

FSCTRL0 = 0x00

MDMCFG4 = 0x09

MDMCFG3 = 0xF9

MDMCFG2 = 0x06

MDMCFG1 = 0x22

MDMCFG0 = 0xE5

DEVIATN = 0x00

FREND1 = 0x56

FREND0 = 0x10

MCSM1 = 0x30

MCSM0 = 0x18

FOCCFG = 0x17

BSCFG = 0x6C

AGCCTRL2 = 0x03

AGCCTRL1 = 0x40

AGCCTRL0 = 0x91

FSCAL3 = 0xE9

FSCAL2 = 0x2A

FSCAL1 = 0x00

FSCAL0 = 0x1F

TEST2 = 0x88

TEST1 = 0x31

TEST0 = 0x09

PA_TABLE0 = 0xC0

can you tell me is there any problem with the values
