Anybody have analog TV test equipment?  What's your thoughts on maintaining it?
I have a modular generator, Tek TG2000 and the only thing it has done in the last 16 months is provided some analog signals for Video triggering or some CATV optioned spectrum analyzers.  I wonder if it's relevant anymore for US market.

It's probably a fairly narrow "niche" market.  I just had a TG2000 come in for cal (along with a VM700) that we couldn't cal (for all the obvious 75-Ohm/NTSC/PAL reasons).  There are companies that produce electronics that need to test video things for international markets.  The company I recently left was doing cal's for a major global company.  We supported cal's related to production that had to comply with NTSC, PAL, and even some Russian video protocol (whose name I don't recall).  We couldn't cal them and had to send them out.

The change I think is only to the U.S. television market.  There are still requirements in international and related markets that will likely be around for a while.  The issue I think is whether you support those markets.
