:ACQuire Commands
:ACQuire:POINts[:ANALog]
Command Syntax
:ACQuire:POINts[:ANALog] <points>
<points> ::= {AUTO | <points_value>}
<points_value> ::= desired analog memory depth in integer NR1 format
Sets the desired acquisition memory depth.
• AUTO — puts the oscilloscope into Automatic (default) mode where the optimal
memory depth is selected automatically by the oscilloscope.
• <points_value> — If a numerical memory depth is entered, this puts the
oscilloscope into Digitizer (manual) Mode with the desired number of points.
The Automatic or Digitizer mode setting also affects the sample rate (see the
:ACQuire:SRATe[:ANALog] command).
The actual memory depth used is returned by the :ACQuire:POINts[:ANALog]?
query.
For :SINGle acquisitions, the requested memory depth is used.
When the oscilloscope is running (:RUN command, continuously making
acquisitions) or when the :DIGitize command is used, the requested amount of
memory is halved.
The maximum amount of memory available is halved when both channels in a pair
are turned on. Channels 1 and 2 are one pair, channels 3 and 4 are the other.
Query Syntax
:ACQuire:POINts[:ANALog]?
The :ACQuire:POINts[:ANALog]? query returns the number of data points that the
hardware will acquire from the input signal. The number of points acquired is not
directly controllable. To set the number of points to be transferred from the
oscilloscope, use the command :WAVeform:POINts. The :WAVeform:POINts?
query will return the number of points available to be transferred from the
oscilloscope.
Return Format
<points_argument><NL>
<points_argument> ::= an integer in NR1 format
