1)from the Function Options menu on the trace screen, press  

  ; or

2) select the STORED TRACES option from the SETUP MENU.

moves the cursor up and down in the list of stored traces

exits the STORED TRACES menu and returns to the trace screen

loads the currently selected fiber trace into the trace screen

allows the user to overlay a previously stored trace on top of the currently loaded trace.  Only one trace can be 

overlaid at a time, and the overlay trace is denoted by a dark arrow to the right of the trace information.  Press this 
button again to clear the overlay status

gives the user the option: 1) to delete the currently selected fiber trace; 2) to not delete the selected trace; 3) to 
delete all traces; or 4) delete only traces that have been previously downloaded (see TRACE DOWNLOAD 
STATUS below)

displays the next page of fiber traces if there are more traces than will fit on the screen

TRACE PARAMETER INFORMATION.  Information at the bottom of the STORED TRACES screen shows trace parameter settings 
used when the trace was taken:

n

index of refraction

L

fiber length

P

pulse width

S

step

TRACE DOWNLOAD STATUS.  If the trace has already been downloaded to the PC, this trace will be marked by a green 
checkmark which appears at the right of each trace.
