How to test LNBs?

[mbarnes]

Anyone have some ideas on bench testing LNBs? I've got a box of various LNBs that were taken out of service. Sadly, most have no note or anything indicating what was wrong. I really don't have the time to mount on a dish, align to sat, and check out. I do have a spectrum analyzer that will power the LNB and display the signal.

Any ideas on a signal to check would be appreciated.

The easiest way ist to mount a dish and reciever and change the lnb's after you test them.

The DigiSat and the Acutrac meters have a test for LNB's and the instructions for testing them... you will want them to be at approx. 200 Ma reading... less than 100 Ma or more than 300 Ma and you have problems with the LNB...

IIRC the DPP Twins suck more than 300ma out of my acutrac.

Its just easier to RA them and get new ones from the DISH Network service department.
