Hello,
I am using ISP1907 which has NRF52833. I get the IQ data and configuration from serial as:
DF_BEGIN ['IQ', 0, 0, 11, -9, -213] ['IQ', 1, 8, 11, -209, 23] ['IQ', 2, 16, 11, 38, 208] ['IQ', 3, 24, 11, 214, -32] ['IQ', 4, 32, 11, -43, -212] ['IQ', 5, 40, 11, -213, 49] ['IQ', 6, 48, 11, 50, 206] ['IQ', 7, 56, 11, 200, -72] ['IQ', 8, 72, 12, 59, 109] ['IQ', 9, 80, 255, 15, -28] ['IQ', 10, 88, 1, -201, 21] ['IQ', 11, 96, 255, -40, 101] ['IQ', 12, 104, 2, -6, -84] ['IQ', 13, 112, 255, 15, -35] ['IQ', 14, 120, 10, 147, -99] ['IQ', 15, 128, 255, 32, -145] ['IQ', 16, 136, 3, 25, -152] ['IQ', 17, 144, 255, -32, -58] ['IQ', 18, 152, 9, 54, -58] ['IQ', 19, 160, 255, 7, -85] ['IQ', 20, 168, 4, -35, -97] ['IQ', 21, 176, 255, 6, 11] ['IQ', 22, 184, 8, 196, -59] ['IQ', 23, 192, 255, 5, -111] ['IQ', 24, 200, 7, -14, 100] ['IQ', 25, 208, 255, 25, 23] ['IQ', 26, 216, 6, -119, -1] ['IQ', 27, 224, 255, -9, 45] ['IQ', 28, 232, 5, 17, -84] ['IQ', 29, 240, 255, -67, -83] ['IQ', 30, 248, 12, -115, -51] ['IQ', 31, 256, 255, 17, 34] ['IQ', 32, 264, 1, 133, -156] ['IQ', 33, 272, 255, -38, -105] ['IQ', 34, 280, 2, 54, 58] ['IQ', 35, 288, 255, -7, 47] ['SW', 2] ['RR', 3] ['SS', 3] ['FR', 2426] ['ME', 33] ['MA', 279] ['KE', 29] ['KA', 276] DF_END
In SW RR SS part, it is said
SW: 2
RR: 3
SS: 3
However, from the table provided by white paper https://docs.nordicsemi.com/bundle/nwp_036/page/WP/nwp_036/iq_sampling.html, it is said that
So, I was wondering what SW: 2, RR: 3, SS: 3 do mean.
for example, SW:2, does it mean that TSWITCHSPACING is 2us ?,
But, for RR:3, the table from white paper only indicates the option for TSAMPLESPACINGREF 1us
also for SS:2, the table only indicates TSWITCHSPACING is either 2 or 4us.
is there any documentation explains that? or do they mean something else?
Thank you
