Radio Alignment Procedures: Softpot 6-3
Figure 6-3. Typical Softpot Screen
Adjusting the softpot value sends information to the radio to increase (or decrease) the voltage in the
corresponding circuit. For example, left-clicking the UP spin button in the New Softpot Value scroll
box on the Reference Oscillator screen instructs the radio’s microcomputer to increase the voltage
across a varactor in the reference oscillator, which increases the frequency.
In ALL cases, the softpot value is just a relative number corresponding to a digital-to-analog (D/A)
generated voltage in the radio.
Perform the following procedures in the sequence indicated.
NOTE: Some of the following screens may vary depending upon the radio under test and the version
of tuner software you are using. Refer to the software’s online help.
When keying the radio during a test, always
transmit into a
dummy load.
