Record/Playback (SA Option)
SA Data Recording:
— Data can be recorded at the Raw Meas block where data is acquired after
ResBW, VideoBW, and Detector processing, but before any trace state
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.
— Data is ALWAYS played back at the same location in the data flow: just after
the Raw Meas block, through all currently active Traces, and onto the
display.
— See an example using Record Playback with Max Hold traces in “Record
Playback Example (SA Only)” on page 284.
