Other Parts Discussed in Thread: CC1125, CC1175, CC1120

HI, I am looking at using CC1125 or CC1175 in design for radio to meet ETSI 300-113. I am concerned with adjacent channel power (> = -60dBc) and have recently found a TI presentation on LPRF (from 2011) showing spectral plot for CC1120 in narrow band (12.5KHz channel) transmit at 9K6bps 4GFSK.

What setup was used to capture the spectral plot, (ie instrument name and type) and what were the settings used (video and resolution bandwidths etc) and how was the C1120 set up.?.

Having obtained a set of evaluation modules and RFStudio I would like to replicate the test.

Do you have a link to the presentation you are referring to?

I have found the relevant presentation in its latest form on your web site by searching for "LPRF performance line". Its a power point presentation. Sorry can seem to get the actual link. The spectra in question are on page 52.

Sorry, I was not able to find the presentation you are referring to without a title or a link.

The plot was most likely created using a spectrum from Rohde & Schwarz and I would assume RBW in the 300 - 1000 Hz range since it's a narrow band measurement.
