Satellite, TP search: functions and settings
Important parameters such as LNB command and control signals are also permanently set in the TP search
menu. Incorrect settings lead to malfunctions !
After selecting the desired satellite from the list of satellites offered, by pressing the OK button, you are now in the TP

Satellite, SAT identification
The SAT Identification function is used to easily identify satellites. For example, on a BIS switch to which several
satellites are connected, this function can be used to identify the connected satellites in the simplest possible way.
The example below shows the automatic identification of satellites during the search. The UPM 1400 searches for all
satellites until it receives a signal for LNB 1 with the correct satellite ID. In the example below, the Astra 19.2E
satellite has been detected at the DiSEqC LNB1 port. Change the DiSEqC port to LNB2 and the device will start
searching from the beginning and display the connected satellites for LNB2 after scanning. You can cancel the
search at any time by pressing the EXIT button.

Satellite plotting, introduction
This tutorial walks you through the complete installation of a satellite reception using the example of the Astra
located at 19.2° East.

UPM 1400
EN 18
Always charge the UPM 1400 before using it. Familiarize yourself with the device before making any
antenna adjustments, especially if you plan to mount an antenna on a roof. This saves you time and gives
you the security you need when setting up the antenna
Preparation and basics:
The antenna mount must be aligned very precisely, i.e. the antenna mast must be level and firmly fixed so that the
subsequent installation of the antenna can be carried out without problems.
Mount the antenna on the bracket and tighten the antenna screws so that the antenna can always be aligned and
moved.
Adjust the elevation angle according to your location.
Elevation angle
It must be ensured that orientation to the south is possible without obstacles. If there is no clear view, a
satellite dish cannot be installed at this stage.
Azimuth angle
The azimuth angle (length angle) defines the horizontal alignment of the antenna. For now, align the antenna exactly
south. The azimuth angle (angle of length) defines the horizontal alignment of the antenna. For now, align the
antenna exactly south.
Satellite configuration, alignment settings
Now that the antenna is pointing south and the elevation angle has been set to suit your location, the UPM 1400 can
be connected to the LNB.
The easiest way to line up is through the TP search menu. The detailed explanation of the different functions of this
menu item can be found in chapter 5.1.
From the main menu, select the Satellite menu, then select the TP search menu.
Now you will see the list of satellites and select "Astra1 (19.2E)".
You are now in the TP search menu and should see the same display as in the sample image below. If the LNB is
connected, the POW screen should now show at least a signal level of 60 dbµV. Otherwise, the cable is not
connected to the LNB, the LNB is defective or the measuring device does not deliver any voltage.
Parameters:
If you're not sure what settings to make, use the values exactly as shown in the example below.
If you are using a Quattro LNB, you must ensure that the signal cable is connected to the correct
output on the LNB. The settings of the following example are designed for the measurement of a
Horizontal High band transponder (output marked in yellow on a QUATTRO TRIAX LNB

UPM 1400
19 EN
Satellite configuration, pointing using the measuring device
Pointing:
Now turn the antenna carefully, very slowly and never jerkily to the east (to the left when standing behind the
antenna).
After only a few centimeters of rotation, the bar graphs showing the MER and BER values of the measuring device
deviate. At this point, the measuring device has connected to the transponder and is evaluating the data.
The NIT value now appears and indicates which satellite has been read and is received from the meter.
If no deviation is visible even after turning the antenna for a long time, you may have turned too jerkily or too quickly
and "jumped" the satellite. Then slowly and carefully turn the antenna south or repeat from the southern starting
point until you receive signals from that satellite.
Fine tuning:
Antenna fine tuning begins now. Adjust the azimuth and elevation angles to get the highest possible MER value. The
MER value is the most important parameter in terms of signal quality. Turning the antenna a few millimeters can
cause significant signal changes.
At the end, all antenna screws should be tightened and the antenna pointing is completed successfully.
