:ACQuire:POINts[:ANALog]
(Memory depth)
Command
:ACQuire:POINts[:ANALog] {AUTO | <points_value>}
The :ACQuire:POINts[:ANALog] command sets the requested analog
memory depth for an acquisition. Before you download data from the
oscilloscope to your computer, always query the points value with the
:WAVeform:POINts? query or :WAVeform:PREamble? query to determine the
actual number of acquired points.
You can set the points value to AUTO, which allows the oscilloscope to
select the optimum memory depth and display update rate.
<points_value> An integer representing the memory depth.
The range of points available for a channel depends on the oscilloscope
settings of sampling mode, sampling rate, and trigger sweep. The following
tables show the range of memory values for the different memory options.
