Channel Bandwidth (Marker Channel Bw); Marker (Channel Bw Marker); Carrier (Ref. Noise Carrier); Bandwidth Of The Spectrum Measuring Filter (Measure Bandwidth) - Promax PROLINK-3 Premium Manual De Instrucciones

To modify the frequency where you want to measure noise level, accede to the
menu functions and select the Carrier
Spectrum mode, turn the rotary selector to place the marker on the frequency where
you want to measure the noise level or well, press key
noise frequency will be erased and using the keyboard introduce the new value. Finally
accede to the functions menu again and execute the Ref. Noise
that you can tune new carrier frequencies by turning the rotary selector.
4.10.1.7 Channel Bandwidth (Marker
(Only in Channel Power measurements). Permits to define channel bandwidth.
To modify the channel bandwidth, that is to say the power integration limits,
accede to the menu functions and select the Marker
again in the Spectrum mode, turn the rotary selector to modify it or well press key
[31], current channel bandwidth will be erased and using the keyboard introduce the
new value. Finally accede to the functions menu again and execute the Channel BW
Marker function so that you can tune new carrier frequencies by turning the rotary
selector.
4.10.1.8 Marker (Channel BW
(Only when measuring Channel power and after defining the Channel
bandwidth). Permits to change the tuning frequency by means of the rotary selector.
4.10.1.9 Carrier (Ref. Noise
(Only when measuring C/N Referenced and after defining the Reference noise).
Permits to change the tuning frequency by means of the rotary selector.

4.10.1.10 Bandwidth of the Spectrum Measuring Filter (Measure bandwidth)

The frequency resolution of the Spectrum Analyser mode is determined by the
bandwidth of the measuring filter when displaying the spectrum. This parameter is
fundamental given the increasing density of channels present in all TV transmission
systems.
To alter the bandwidth of measurement select the Spectrum Analyser functions
menu, then turn the rotary selector [4] to the Measure bandwidth function and press.
The screen will show a window displaying the values which can be selected. Turn the
rotary selector [4] to the chosen bandwidth and activate it by pressing the selector
again.
