[QUOTE="Terryl, post: 750300, member: 369937"] Sorry for the misunderstanding Ralph, I did not say he was going to mod the unit to 14 gig, but when using any test equipment for any project you should select equipment that will cover the range you need and then some so your not working at the stops or limitations of the test equipment, the spectrum analyzer being used should work out to 3 times the design frequency of the device under test, this is to look for 3rd order harmonics or intermod. If your going to try and work on a LNB your going to need some sort of test equipment to make sure your not going to be affecting the guy down the street with some sort of spur or harmonic you have accidentally created by changing something in the LNB. Or testing it to see if the smoke is still there. [/QUOTE]
