-# This configuration file describes the insertion loss of the cabling

-# a 6 ft long RG-316 coaxial cable going from an N connector on the
-# CMU200 end to an SMA on the DUT end.

-# The numbers have been taken from this online calculator:

-# having entered the cable type as RG-316, the length as 6 ft
-# and the center frequency of each band.

+# This file is an EXAMPLE of the cable configuration file for fc-cmu200d.
+# The cable config file describes the insertion loss of the cabling
+# between the CMU200 and the DUT for each uplink and downlink frequency
+# band; knowing exactly what this cable loss amounts to is very critical
+# for proper calibration; simply ignoring or neglecting this cable loss
+# or putting in "off the wall" numbers is *not* an acceptable option.
+#
+# The numbers given in this EXAMPLE file have a chance of being correct
+# *only* for the specific cabling setup which the Mother of FreeCalypso
+# currently uses in her lab; if you are setting up your own calibration
+# station, you need to replace them with your own numbers that are
+# correct for YOUR cabling setup.
