This key lets you make a trace visible or not. In 
Blank, traces do not display nor appear on 
printouts but are otherwise unaffected. They may be queried and markers may be placed 
on them. 
Note that the action of putting a trace in 
Blank does not restart the sweep and does not 
restart averaging or hold functions for any traces.
Dependencies / Couplings • Setting the trace type (even to the type it was already in) puts 
the trace in 
Show
• Loading a trace from a file puts that trace in Show regardless of 
the state it was in when it was saved.
Preset
Show for Trace 1; Blank for 2
