:WAVeform:POINts:MODE
(see page 782)
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 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 62,500-point
(maximum) representation of the raw acquisition record. The measurement
record can be retrieved 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),
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 162) or
the :DIGitize command (see page 143) in the root subsystem) in order to return
more than the measurement record.
• :TIMebase:MODE must be set to MAIN.
• :ACQuire:TYPE must be set to NORMal or HRESolution.
• MAXimum or RAW will allow up to 100,000 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.
Query Syntax
:WAVeform:POINts:MODE?
The :WAVeform:POINts:MODE? query returns the current points mode. Setting the
points mode will affect what data is transferred. See the discussion above.
