About Radio design by using CC11252 & SKY65313 FEM and radio testing

Other Parts Discussed in Thread: CC1125

Hi TI Team,

Q: How can I measure the channel Band width of radio (designed by using CC1125 & SKY65313 FEM) in transmitting mode by using Anritsu site master S322D Spectrum Analyzer?

Q: How many radio's can I use in 1MHz Band (865 to 866MHz) width with 6.25kHz/12.5kHz/25kHz Channel spacing for data transmitting and receiving mode.

Please clarify my queries.

Thank you,

Regards,

Tarakewara rao

    Q1) I answered this here: e2e.ti.com/.../436721. If you on the other hand mean occupied bandwidth you can measure this by setting the RBW as low as possible and use the markers. Some spectrum analyzers also has this as build in measurement method
    Q2) Which output power do you plan to use? The number of channels will be (sub-band width)/(channel spacing). You have to check which sub-band you are allowed to use.
