niRFSA Configure Number of Samples
Configures the number of samples in a finite acquisition or configures the device to continuously acquire samples. If you configure the device for finite acquisition, it acquires the specified number of samples and stops the acquisition. You can configure the device to acquire multiple records using the niRFSA Configure Number of Records VI, each record containing the number of samples specified in this VI. The default number of records to acquire is 1.
If the device is configured to continuously acquire samples, it continues acquiring data until you call niRFSA Abort to abort the acquisition. The device stores data in onboard memory in a circular fashion. Once the device fills the memory, it starts overwriting previously acquired data from the beginning of the memory buffer. Retrieve the samples using the niRFSA Fetch IQ VI as they are being acquired to avoid data being overwritten before you can retrieve it.

instrument handle identifies your instrument session. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session. | ||||||
 |
number of samples is finite specifies whether to configure the device to acquire a finite number of samples or to acquire samples continuously. | ||||||
 |
samples per record specifies the number of samples per record if number of samples is finite is set to TRUE. | ||||||
 |
error in (no error) describes error conditions that occur before this VI runs.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session. | ||||||
 |
error out contains error information. If error in indicates that
an error occurred before this VI ran, error out contains
the same error information. Otherwise, it describes the error status that this VI
produces.
