SS is signal strength.  CN is carrier to noise ratio.   They basically indicate the same thing, but their scale may be different.   You can't compare the absolute magnitude of the values from different types  of receivers,  only do relative comparisons.   Other receivers can report dBc, etc.  And Trimble devices can report AMU (amplitude measurement units).  Some Trimble devices don't support dBc readings.  By switching a Tbolt between AMU and dBc, I worked out a table that Lady Heather uses to convert AMU to dBc to that those devices can display the more common dBc values.  On the Trimble devices you set the signal level mask in AMUs.
