Command Syntax
: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 three 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 when :SYSTem:PRECision is
OFF, from any source.
• The third is referred to as the precision analysis record and is a
10K- point (maximum) representation of the raw acquisition record. The
precision analysis record can be retrieved when :SYSTem:PRECision is
ON, from analog sources.
If the <points_mode> is NORMal and :SYSTem:PRECision is OFF, the
measurement record is retrieved.
If the <points_mode> is NORMal and :SYSTem:PRECision is ON, the
precision analysis 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.
Considerations
for MAXimum or
RAW data
retrieval
• The instrument must be stopped (see the :STOP command (see
page 174) or the :DIGitize command (see page 146) in the root
subsystem) in order to return more than the measurement record or
precision analysis record.
• :TIMebase:MODE must be set to MAIN.
