bladeRF calibration
« on: February 07, 2015, 02:10:00 PM »
published bladeRF for calibration isn't good for dummies at all.
What's the best way to calibrate bladerf in order to use YateBTS ?
1. bladeRF-cli -i
2. set rxvga2 27
3. set rxvga1 25
4. set txvga2 -14
5. set txvga1 0
4. cal table dc rx 1841.6M 1842M 1000
5. cal table dc tx 1841.6M 1842M 1000

like this?
or it should be standard cal table dc tx/rx without freq ?

The values for rxvag1, rxvga2, txvga1 and txvga2 are set by YateBTS from the configuration file. The default values in that file should work without changes.

If you are using a Lab Kit, then we calibrated the frequency for you already. If not, for most BladeRF radios we have seen, the frequency offset setting in YateBTS is in the range 165-170.

There are also calibrations for DC offset, but single-carrier GSM is not very sensitive to DC offset.
