Title: rx_acqrange
Post by swalif on Sep 27th, 2008 at 10:38pm


hello,


I have small question what (rx_acqrange), (tx_acgrange) means ?

I'm presuming that this is a value in the option file.

This value is set by iBuilder when you set the stability value for an LNB.  I recall that the options file version is in Hz and iBuilder presents it in MHz.  Some other voodoo math may be applied, but essentially the value is set through "stability" on the LNB.

Unless you have troubles - this value should be manipulated by iBuilder in the LNB description - not on a "per remote option file" basis.

One more bit - the value impacts the remote's (or hub's) ability to pick up signals.
In the case of the remote, a larger ("wider") value increases the RF spectrum range that will be looked at to find the hub carrier.  Ultimately this will also impact the speed to get a RX lock - more of a range = more places to look.  Not enough range and you may miss the carrier.  As with everything, a balance is necessary.

Hope that makes sense.
