PCB LINKS
Links enable various options on the TDS9092. The left
column shows the option set on shipment. The links E F G V W X Y Z are
push-on jumpers. Links A B C and D are solder links set on manufacture
and should not need altering. To change a soldered link use a clean desoldering
tool that will not spray particles of solder around, or apply a solder
blob if the link is unmade. Use a very fine-tipped soldering iron. Connections
on delivery are marked * .
