If I wanted to Purchase a Spec analyzer, How many GHZ is needed so I can use it for setting up my dish.

thanks in advance

I would want one that would go to 2200 Mhz to cover the whole possible L band IF...

The signals on both C and KU are downconverted to L band. Any consumer satellite receiver is just an L band receiver...it receives from 950 to 2150 Mhz

If you're not bothered by using eBay, you might be interested in this.  I have one and it works great.  $300 and free shipping to the lower 48.

How would be the best way to incorparate a SA into a system? Run a line of Rg6 from a multiswitch that is currently being pushed around by a specific receiver?.Does it see V and H in the same screen? Does that one you mention see S2 cracklin?All new to me....Thanks.

most satellite SA can control polarity, switchs, etc some even control the motor. So treat it like adding another receiver

It sees everything in a particular band.  The SA I have sees everything from 700MHz through to 2200MHz.  However, it doesn't tell me what type of signal it is.  It only tells me that the signal is there.  I can see the power levels of signals.  I can see how many MHz wide it is, which doesn't necessarily correlate to symbol rate.  Like updatelee said, treat it like a receiver, in most cases.  However you can connect just about any signal source to it so long as the frequency you are looking for is within the range that the SA will tune.

I can however tell the difference between an analog and digital signal just by looking at the waveform.  An analog is pointy, and a digital one generally plateaus.   

That particular one that is on ebay is the same model that I have, and the same fella I bought mine from.  It can control polarity and 22kHz switches.  That model can also be connected to your computer through a serial port to take screen captures and monitor waveforms.  The software for mine can be configured to email somebody if a signal drops by so many db if I wanted it to.

the satlook does analog as well, analog signals imo look like a flickering flame. If your only going to use the SA for satellite then having one that locks the signal to determine the SR and fec is nice. Some show the constelation which is nice as well. BER and SNR is nice as well as you can really use it to tweak a dish to its max, much more so then just signal strength.

What about the built in SA in the DR.HD-F16 receiver. Does anyone have any feedback on its functionality?

watch the video and youll see 5m and 2m steps as well. you can also record to shared network drives. i think i want one.

crackt out,.

I picked one up. There just 30 min from where I live. I had to replace the eight push switches on the front left, radioshack had them. Now I can get to menu 4  "band aid" switch the freq display to show the right freq for Ku  or C. I didn't get any software and mine just has a RS-232 serial port in the back says internal use only. The manual is easly got on the internet and it shows that you need a 45D-E for the software to work I have just the 45D. Anyways I do like the graphics looks like your avatar picture cracklincrotch

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
