  Quite right, TD, but... I specifically mentioned this type of
instrument because I felt that it would already have a good deal of the
basic electronic requirements in place. Yes, a regular 'scope would also
suffice, perhaps cheaper, but an old Vectorscope would come without the
'baggage' of sweep and trigger circuits... viewing the Project from a
K.I.S.S. standpoint, there is a decision tree to be followed....

 Cheers
