scale is displayed indicating the minimum, maximum, and current
value of the softpot setting, as shown below:
Adjusting the softpot value sends information to the radio to increase
or decrease a DC voltage in the corresponding circuit. In all cases, the
softpot value is just a relative number, corresponding to a D/A (digital-
to-analog) generated voltage or digitally-controlled frequency in the
radio. All standard measurement procedures and test equipment are
applicable and are NOT affected in any way.
