Acquire Commands
The ACQuire subsystem commands set up conditions for executing a
:DIGitize, :DIGitize:NDISplay or :RUN root level command to acquire
waveform data into capture memory or a :STReam root level command to
stream waveform data out of the ODI links. The commands in this
subsystem select the sampling frequency and the number of data points.
:ACQuire: SRATe[?]
Command
:ACQuire:SRATe {S16G | S32G}
The command sets the acquisition sampling rate.
S16G
16GSa/s
S32G
32GSa/s
Query
:ACQuire:SRATe?
The query returns the acquisition sampling rate.
Example
Command
:ACQuire:SRATe S16G
:ACQuire:POINts[?]
Command
:ACQuire:POINts <points_value>
The command sets the requested memory depth for an acquisition into
capture memory.
<points_value>
An integer representing the memory depth per
channel. When raw data is captured, the value denotes the number of
samples. When IQ data is captured, the value denotes the number of IQ
sample pairs.
The minimum and maximum values and the granularity of the points
available for a channel depend on the sampling rate, the data processing
mode (Direct/DDC) and the decimation factor. If the passed parameter
does not fulfill the granularity the value is adjusted to the next higher
supported value.
