processing. 
  Data can be recorded from Traces 1,2,3, or 4 which includes the trace state 
(Max Hold, Min Hold, and so forth.  
  Recording from a Clear/Write trace yields exactly the same data as recording 
from the Raw Meas block.

the Raw Meas block, through all currently active Traces, and onto the display.  
  See an example using Record Playback with Max Hold traces on page 126.
