To identify the 4 polarities coming from the output of a VHVH converter or the 4 cables of a riser column in a distribution made with a multiswitch, one solution is to select 4 different transponders in the field meter, each for its own POLARITY and BAND of reference.

For convenience *, we will refer to the following 4 transponders referring to the satellite Hot Bird positioned at 13° East:

• TP124 / VL = Vertical Low ( 13 Volt – 0 KHz ) – Local Oscillator ( OL ) 9750 MHz;
• TS125 / HL = Horizontal Low ( 18 Volt – 0 HHz ) – Local Oscillator ( OL ) 9750 MHz;
• TS52 / VH = Vertical High ( 13 Volt – 22 KHz ) – Local Oscillator ( OL ) 10600 MHz;
• TS67 / HH = Horizontal High ( 18 Volt – 22 KHz ) – Local Oscillator ( OL ) 10600 MHz.

Subsequently, for each selected transponder, it will be necessary:

• Check the AUDIO VIDEO content of the first service / television program of the transponder visible on the screen (if not coded);
• Check the other AUDIO VIDEO services contained in the transponder;
• Check the FREQUENCY ERROR ( FREQ Err ) of the LOCAL OSCILATOR ( OL ).

NOTE:

If the FREQUENCY ERROR value is very high, indicatively over +/- 3.0 MHz and the TELEVISION services that appear on the screen do not correspond as shown in the examples below, it means that we may have connected the cable and therefore the incorrect polarity in the instrument. for identification;
Therefore select another transponder or change the cable in the instrument.

1) Prepare the instrument for operation in SATELLITE mode;

2) Press the PLAN KEY and select the SATELLITE > HOT BIRD at 13° East ( HBIR13 );

3) Press the SAT KEY to make the measurements;

4) Select the first reference transponder, TP124 – VL ( Vertical Low ):

TP124 – Network RAI – Service Rai 1 – FREQ Err: 0.3 MHz

Other TV services available in the trasponder:
Rai 1 / Rai 2 / Rai 3 etc.

5) Select the second reference transponder, TS125 – HL ( Horizontal Low ):

TS125 – Network RAI – Service Rai News 24 HD – FREQ Err: 0.0 MHz

Other TV services available in the trasponder:
Rai News 24 / Rai Gulp HD / Rai YoYo HD etc.

6) Select the third reference transponder, TS52 – VH ( Vertical High ):

TS52 – Network RAI – Service Rai 1 HD – FREQ Err: 0.1 MHz

Other TV services available in the trasponder:
Rai 1 HD / Rai 2 HD / Rai 3 HD etc.

7) Select the fourth reference transponder, TS67 – HH ( Horizontal High ):

TS67 – Network Sky – Service CNBC HD – FREQ Err: -0.3 MHz

Other TV services available in the trasponder:
Comedy Central / Nick Jr / Caccia e PESCA etc.

NOTE:

• The list of TV and RADIO services contained in the transponders listed above may be subject to changes by the television operator without notice;
• * The 4 reference Transponders selected are entirely causal, therefore it is possible to select 4 of them from the complete list of all the Transponders of the Hot Bird satellite at 13 ° East;

• The MENUS (writings and graphics) of the figures represented in the following F.A.Q., may vary from model to model and without notice.
