Considerations for MAXimum or RAW data retrieval

(see page 530)

:WAVeform:POINts:MODE <points_mode>

<points_mode> ::= {NORMal MAXimum RAW}

The :WAVeform:POINts:MODE command sets the data record to be transferred with the :WAVeform:DATA? query.

For the analog sources, there are two different records that can be transferred:

•The first is the raw acquisition record. The maximum number of points available in this record is returned by the :ACQuire:POINts? query. The raw acquisition record can only be transferred when the oscilloscope is not running and can only be retrieved from the analog sources.

•The second is referred to as the measurement record and is a 1000 point (maximum) representation of the raw acquisition record. The measurement record can be retrieved at any time, from any source.

If the <points_mode> is NORMal, the measurement record is retrieved.

If the <points_mode> is RAW, the raw acquisition record is used. Under some conditions, such as when the oscilloscope is running, this data record is unavailable.

If the <points_mode> is MAXimum, whichever record contains the maximum amount of points is used. Usually, this is the raw acquisition record. But, if the raw acquisition record is unavailable (for example, when the oscilloscope is running), or if the reconstruction filter (Sin(x)/x interpolation) is in use, the measurement record may have more data. If data is being retrieved as the oscilloscope is stopped and as the data displayed is changing, the data being retrieved can switch between the measurement and raw acquisition records.

•The instrument must be stopped (see the :STOP command (see page 120) or the :DIGitize command (see page 96) in the root subsystem) in order to return more than 1000 points.

•:TIMebase:MODE must be set to MAIN.

•:ACQuire:TYPE must be set to NORMal, AVERage, or HRESolution. If AVERage, :ACQuire:COUNt must be set to 1 in order to return more than 1000 points.

•MAXimum or RAW will allow up to 8,000,000 points to be returned. The number of points returned will vary as the instrument's configuration is changed. Use the :WAVeform:POINts? MAXimum query to determine the maximum number of points that can be retrieved at the current settings.
