5.4.1.1 RF Level and Frequency Display
The measured RF power and frequency of the input signal is displayed both numeri-
cally and graphically.
Figure 5-19: RF level display
The following results are provided:
●
Numeric power level in dBm ("Lev")
For measurements on two frequencies: individual and sum power levels
●
Measured frequency offset to the nominal frequency in kHz
●
Numeric frequency offset of measured power
●
Numeric power sensor level in dBm (if available; "NRP")
●
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
●
If applicable: overload messages
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.
