DIRECTVDIRECTV ASL-1 SWM Alignment Signal Locator Tool for ACCUTRAC DIGISAT SAT METER

Can i use this with a digital meter? and will it work with swm?

How do you get the required 21v of power to this unit? Will just hooking it up to a 21v power inserter work?

On my digital meter, what lnb settings should i use once i have it all hooked up? (e.g. lo frequency, etc.)
