●
Numeric frequency offset of measured power
●
Bargraph indicating the power and a color-coded overload state, where:
–
red : overload state, check message
– yellow : power approaching overload state
– green : power in a valid range

Overload messages
The following messages indicate an overload:
●
"RF Overload"
Overload of the input mixer or of the analog IF path.
●
"IF Overload"
Overload of the IF signal.
●
"ADC Overload"
The dynamic range of the AD-converter is exceeded (clipping).
A combination of these overloads is also possible.
In all cases, set the RF attenuation to normal or low distortion (for RF input), or reduce
the input level.
