Re: Tektronix 067-0625-00 Peak to Peak Detector Battery

I have two of these. The batteries are used for is to provide a DC offset "bucking voltage" of 0.3V
via a resistor network and adjustable resistors R8/R9 that sets zero output at 1.2V p-p.

If R10/R11, which are usually 120k at 1.5V are increased to 348k then the common 3V tagged cells could
be used with the same sensitivity of adjustment of R8/R9.

Having just worked that out, I've just worked out how to resurrect my own!

Just need to find a suitable tagged 3V battery that can take 7.5uA draw 24/7.
