Re: Aeroflex (IFR) Questions

There are no markings but IFR;s on the unit. It is the same for the 1200. 1500,1600 and maybe others.

It is strange how the battery pack is made of unoptainum. I can not even find a bad pack to be sent out for rebuilding.

9101 battery

I picked up a used Willtek (Aeroflex) spectrum analyzer recently. It did not come with a battery. The unit seems to work fine.

I can not find a source for the battery. It seems to be not available anywhere. Does anyone know where I can get a battery for it?
