Hi, a very interesting device - and I'm sorely tempted, but on a restricted budget so looking for a used unit.
Is there any documentation on the various hardware revisions and the differences between them ? Just in
case there are any problematic versions.
I have also seen mention of an -H version - what is that ??
I have seen a UTube video describing it used with an external mixer to produce a tracking generator
to look at filter performance.? I already have a small selection of SMA mixers and that would be a very
useful tool.
TIA
Dave
