Chapter 4: RF SIGNAL TUNING 59 June 2022
icon MK appears). When the Marker is ON at the top right corner a window
pops up with the following data:
•Freq: Frequency where is placed the marker.
•Level: Power level at the frequency where is placed the marker.
•ΔF: Difference of frequency between the marker and the main cursor.
•ΔL: Difference of power level between the marker and the main cursor.
Marker Trace: It allows the user to select the trace to place the marker
on:
•Normal: It places the marker on the spectrum trace in real time.
•Reference: It places the marker on the spectrum reference trace. To make
a spectrum reference use the Reference function.
•Max. Hold: It places the marker on the max. hold trace. To make a
maximum hold trace use the Max. Hold function.
•Min. Hold:It places the marker on the min. hold trace. To make a
minimum hold trace use the Min. Hold function.
Max. Hold:(Off/Permanent/Curtain). It allows the user to display the
current signal with the maximum values measured for each frequency.
The OFF option disables this function. The Curtain option displays the
maximum values in blue for a moment with the current signal. The
Permanent option maintains maximum signal on the screen. This option is
especially useful for detecting sporadic noises.
Min. Hold: (Off/Permanent/Curtain). It allows the user to display the
current signal with the minimum values measured for each frequency. The
OFF option disables this function. The Curtain option displays the
minimum values in green for a moment with the current signal. The
Permanent option maintains minimum signal on the screen. This option is
useful for detecting interferences in TV cable or identify deterministic
interference in analogue and digital channels.
Persistence: When active, the signal is displayed on a coloured
background. The signal prior to current signal persists for a while before
disappearing so the user can see how the signal changes easily.
Detector Type: (PEAK/RMS). It allows the user to select between
maximum PEAK detector or RMS detector. The maximum peak detector is
mainly used for analogue modulated signals, while the RMS option is the
right choice for digital modulated signals. The max PEAK detector is
mostly used for analogue modulated signals, while the RMS is the proper
choice for digital modulations. The maximum peak detector causes the
noise floor to rise, according to the RMS to peak ratio. That same effect
causes digital signals to apparently grow in level when maximum peak
detector is used.
Resolution Bandwidth (RBW): Resolution filters available are: 100 kHz,
200 kHz* and 1000 kHz**. According to filter selected maximum and
minimum span changes (for more details refer to “Spectrum Analyzer
Mode” on page 217).
