The Ingress function provides a spectrum analysis of the Reverse or Forward path.
The reverse path analyzes the spectrum between 4 to 42 MHz (6 MHz channel plan) or 4 to 65 MHz (8 MHz channel plan).
The forward path analyzes the spectrum between 54 to 1000 MHz (6 MHz channel plan) or 108 to 1000 MHz (8 MHz
channel plan). The forward path spectrum is initially displayed around a user selected center frequency with a 50 MHz
bandwidth.
Once the measurement is started, the user can select the wheel icon on the left bottom part of the screen.
Once selected, then by pressing the up or down arrow (or tapping on the corresponding arrow of the wheel on the screen) the
attenuation (y axis) will be changed, by 10 dB steps.
By pressing the left or right arrow (or tapping on the corresponding arrow of the wheel on the screen) the spectrum can be shifted
by one page (Forward path only).
Once the measurement is paused (green arrow pull down menu) then three markers are made available. Once a marker is
positioned to the proper location, then the frequency and level measurements for the location are performed.
