[ANSS-netops] Earthworm Guide Channel Triangle Wave Generator

[David C Wilson]

Hello,

I am sending a note here on behalf of HVO, they are experiencing problems
with their Earthworm Guide Channel Triangle Wave Generator.  It seems to
be producing spikes that are causing DAQ restarts and subsequent data 
gaps.

Does anyone have a spare Triangle Wave Generator or at least the 
schematics
so that they can build a new one?

Thanks,
Dave
