:WAVeform:POINts:MODE
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 or digital 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 or digital
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
128K- 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
) or the :DIGitize command (see
) in the root
subsystem) in order to return more than the
measurement record
or
precision analysis record
.
