Raw Main Time (GSM/EDGE/EDGE Evo)

Raw Main Time is the raw data read from the input hardware or playback file. This trace is similar to Search Time with the following exceptions:

The data has not had time corrections applied, so the Raw Main Time trace displays a "CAL?" trace LED.
The data has not gone through the VSA's software resampling filters so is generally not sampled at the specified sample rate.
The data has a wider bandwidth than the measurement span would indicate.
The length of this trace is longer than the Search Time parameter in order to include extra time data to allow for filter settling.

Raw Main Time data is useful in the following situations:

When Channel, IF Magnitude, or Magnitude trigger types are used, the input hardware detects the trigger so Raw Main Time sometimes gives a better indication of what caused the trigger.
When a recording is played back, the Raw Main Time measurement data shows exactly the samples that are saved in the recording, with no filtering applied or settling removed.
