[W-MBUS] In your RC1180-MBUS datasheet, we can see that the frequency tuning can change between 2 channels in mode S and T (868.3 and 868.95MHz). We chose the 868.95MHz for our transceiver and I would like to know for our test after the production what is the frequency tolerance and if there is a frequency calibration.

The frequency accuracy is measured in the production test and the limit is +/-10 ppm. We also have support for initial tolerance adjustment in the production tester, but due to the low initial tolerance of the module we have not used this tolerance calibration feature in the production tester.
