Re: A-136 CV question

2003-05-04 by Joe Buechler

Timothy, the A136 User's manual says that the signal is split into 
three parts, but no signal flow diagram is provided. (This is only 
the least of the problems with the A136 documentation). The 
signal diagram on the module front panel suggests that the "A" gain 
is applied BEFORE the signal is fed to the positive and negative 
clipping circuits. That's why I made the suggestion that I did.

I suppose I could spend some time experimenting to determine the 
actual signal path, but it's a tedious business without a scope. I 
wish bakis would nudge Dieter to describe the A136 signal path, and 
correct all the errors in the User's Guide while he's at it.
