Advice Needed Vu+ Solo 2 - viewing the signal from the 2nd Tuner?

[jeallen01]

This is probably an easy question for some people (hopefully!) but, at the moment, rather impenetrateable for me: how can I view the live signal from Tuner 2, which is connected to the 2nd section of the Twin LNB on the steerable dish, when using Tuner 1 to select the satellite and channel and drive the dish via USALS?

The reason for asking is that I want to split the signal coming into Tuner 2 to feed the SSA module with vma's s/w and so view the spectrum on the satellite selected using Tuner 1 - but, at the moment, with the Rx setup set to set Tuner 2 as being connected to the 2nd cable to the Twin LNB (hope you understand what I am trying to say!)

Thanks in advance.

Si entiendo bien, esto es lo que tienes.
Tuner1......Motor-Usals---LNB (boca 1 doble).
Tuner2......Segundo hilo de un LNB motorizado (boca 2 doble).

Del cable que conectas al Tuner2, deribar la señal al analizador de espectro, como.?
Lo ideal seria con un splitter 1x2 en el tuner2, no modifica impedancias.
De entrada probaria con una T de conectores F, tendrias 1dB de perdida y puede que no modifique la señal.
Mira con uno y luego con el otro para comparar.

Importante.
Si no recuerdo mal, necesitarias poner un aislador de tension para no averiar el modulo.

If I understand correctly, this is what you have.
Tuner1 ...... Motor-Usals --- LNB (mouth 1 twin).
Tuner2 ...... Second wire of a motorized LNB (mouth 2 twin).

From the cable you connect to Tuner2, derive the signal to the spectrum analyzer, like.?
The ideal would be with a splitter 1x2 in the tuner2, does not modify impedances.
Probably input with a T of F connectors, you will have 1dB of loss and may not modify the signal.
Look with one and then with the other to compare.

Important.
If I remember correctly, you need to put a voltage isolator in order not to damage the module.

Otra opcion/Another option.
Lo conectas directamente al tuner2/You connect it directly to the tuner2.

Thank you

You understand me correctly, and I do have a DC blocker between the splitter and the SSA (for the moment, that splitter is actually a Global PSA120 "Active Splitter" - not a simple T-connector - which does not pass diseqec/USALS commands to the dish, and so thus why it is not in the cable to Tuner 1 because that prevents the dish motor responding to commands from Tuner 1 to move the dish).

Unfortunately, at the moment, the SSA (with vma's very latest s/w) displays absolutely no signal from the 2nd LNB on the dish - hopefully not an LNB/cable issue, but I do need to check that soon!

Thus, so far, there is no obvious "answer" to my question, but I do hope that you, and/or others here, can provide some more information which will help me resolve the issue.

Global PSA120 "Active Splitter".
Se lo que tienes y se como funcionan los comandos DiSeqC.
Es un splitter de 1x2 con un previo de linea incorporado con una ganacia de 13dB.
Soy enemigo de los previos de linea, normalmente su figura de ruido es muy alta y queremos limpieza en la señal.

Los previos de linea si dejan pasar todo al motor/LNB (ordenes DiSEqC 1.3==> Usal y Tono para que el LNB cambie de banda baja/alta).
Nunca use lo que tienes, pon un repartidor normal, perderas 4dB de señal, no es problema para estas pruebas de funcionamiento y sales de dudas.

Para que funcione este repartidor/splitter activo y el 2LNB (LNB twin), el receptor tiene que usar tambien el segundo sintonizador (B.) en otro tp del satelite.
El LNB dobel/twin necisita ser alimentado por cada linea, recuerda que son 2 LNB's dentro de una misma caja

Para verificar el conexionado y funcionamiento de la segunda linea, es muy sencillo.
Como indico, Usa el PIP del VU+Solo2 para verificar su funcionamiento, por ejemplo, si apuntas al AStra a 19'2ºEste, puedes poner TV GALICIA (TVGA) y Canal Sur A. (Andalucia), indicados como referencia para la prueba.
No me gustan los canales, pero para hacer las pruebas, son muy comodos y tienen buen nivel en toda Europa.

Si usando el PIP la segunda pantalla esta negra, ya sabes la causa, algo no esta bien conectado.
Al activar, seguramente tendras lo mismo en las 2 pantalla, cambias de canal y pones otro que use otro TP y veras que ahora el receptor usa los 2 tuner.

Si le das a PIP, luego azul y despues al verde (mover), si pulsas la tecla 0, cambia la forma de la pantalla, una opcion es poner las 2 pantalla a tamño real (50%), muy util para controlar.

Global PSA120 "Active Splitter".
I know what you have and I know how DiSeqC commands work
It is a 1x2 splitter with a built-in preamp with a gain of 13dB.
I am enemy of the previous ones of line, normally its figure of noise is very high and we want cleaning in the signal.

The previous line if you pass all to the engine/LNB (orders DiSEqC 1.3 ==> Usal and Tone for the LNB to change low/high band).
Never use what you have, put a normal splitter, you will lose 4dB of signal, it is not problem for these tests of operation and you leave doubts.

For this active splitter / splitter and 2LNB (LNB twin) to work, the receiver must also use the second tuner (B.) on another satellite tp.
The LNB dobel / twin needs to be fed by each line, remember that there are 2 LNB's within the same box

To verify the connection and operation of the second line, it is very simple.
As indicated, Use the PIP of the VU + Solo2 to verify its operation, for example, if you point to the AStra at 19.2ºEste, you can put TV GALICIA (TVGA) and Canal Sur A. (Andalucia), indicated as reference for the test.
I do not like the channels, but to do the tests, they are very comfortable and have a good level throughout Europe.

If using the PIP the second screen is black, you know the cause, something is not well connected.
When activating, you will surely have the same on the 2 screen, change channels and put another that uses another TP and you will see that now the receiver uses the 2 tuner.

If you give PIP, then blue and then green (move), if you press the 0 key, change the shape of the screen, an option is to put the 2 screen to real size (50%), very useful to control.

El bloqueador dc va en la linea/boca del medidor/analizador de espectro.
Los bloqueadores DC, es un condensador, que no deja pasar la alimentacion, pero si dejan pasar los tonos.
---------------
The dc blocker is on the meter line / mouth of the spectrum analyzer.
DC blockers, is a capacitor, which does not let the power pass, but if they let the tones go by.


En la TV lo veras igual,
Usando webif desde el PC, la imagen del Canal Sur A. sale negro, añadida a mano, por no hacer una foto de la TV.

On TV you'll see it alike,
Using webif from the PC, the image of the Channel South A. leaves black, added by hand, by not making a photo of the TV.

El VU+Solo2 y el VU+DUO2 tienen las mismas opciones/procesador y configuracion, para lo que quieres, son iguales 100%

The VU + Solo2 and the VU + DUO2 have the same options / processor and configuration, for what you want, they are the same 100%

Thank you again for the advice, and I will try out the PIP function, which I have not done that before - as I roughly said earlier , "it is easy when you know something, but difficult if you do not".

I have also ordered a couple of basic F-connector T-splitters, which will be here in a couple of days.

Therefore, hopefully, most of the problems will be sorted out on Friday!

PS: the PSA120 definitely does not pass Diseqc commands - tried mine on both the T/M and the Vu+ receivers, and the PSA 120 does not pass those commands from either Rx.

No es problema para una prueba de funcionamiento.
Recuerda que esta instalado en la linea2, al tuner2 y el PSA 120 no importa que no pase los comandos DiSEqC, mientras deje pasar la alimentacion al LNB.

En el otro post no entro, soy lector, para ver con el equipo que tienes, no importa.
Using the "138MHz-4.4GHz USB SMA Source/Signal Generator/Simple Spectrum Analyzer" for TV/CATV/SAT

Nota:TM-5402 M3/TM-5500DAPCI & EchoStar 3000, Siempre que tenga entrada de LNB y salida.
Si conectas el analizador de espectro en la salida (boca de abajo normalmente) tendras la señal del canal que sintonizas al hacer bucle interno de la señal, la tendras sin alimentacion, pero como siempre, mejor poner el aislador de tension.
----------------------------------------
It is not a problem for a test run.
Remember that it is installed on line 2, tuner2 and PSA 120 no matter that you do not pass the DiSEqC commands, while letting the power to the LNB.

In the other post I do not enter, I am a reader, to see with the team that you have, does not matter.
Using the "138MHz-4.4GHz USB SMA Source/Signal Generator/Simple Spectrum Analyzer" for TV/CATV/SAT

Note: TM-5402 M3 / TM-5500DAPCI & EchoStar 3000, Provided you have LNB input and output.
If you connect the spectrum analyzer to the output (normally downstream) you will have the signal of the channel that you tune when making an internal loop of the signal, you will have it without power, but as always, it is better to put the voltage.

Tengo los equipos del otro post, como tambien tengo un analizador de Espectro en tiempo real, no lo uso.
I have the equipment of the other post, as I also have a Spectrum analyzer in real time, I do not use it.


PD:Al final, tendre que animarme/In the end, I'll have to cheer myself up.
