The ScopeMeasurement type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | FetchInterleavedData |
Gets or sets a value specifying whether to retrieve one array with alternating values on the NI 5620/5621.
|
| FetchInterleavedIQData |
Specifies whether a fetch call retrieves a single waveform with I and Q interleaved, or two separate waveforms.
|
| FetchOffset |
Specifies the offset, in samples, to start fetching data within each record. The offset is applied relative to FetchRelativeTo. The offset can be positive or negative.
|
| FetchRelativeTo |
Gets or sets the position to start fetching within one record.
|
| PointsDone |
Gets the actual number of samples acquired since the last fetch,
relative to the configured value for
FetchRelativeTo, including FetchOffset and for the current configured RecordNumberToFetch.
|
| RecordsDone |
Gets the number of records that have been completely acquired.
|
| RisInAutoSetupAllowed |
Specifies whether the digitizer should use RIS sample rates when searching for a frequency in autosetup.
|
Methods
| Name | Description | |
|---|---|---|
 | Abort |
Aborts an acquisition and returns the digitizer to the Idle state. Call this method if the
digitizer times out waiting for a trigger.
|
| AutoSetup |
Automatically configures the instrument. When this method is called, the digitizer senses the input signal and automatically configures many of the instrument settings.
If a signal is detected on a channel, the driver chooses the smallest available vertical range that is larger than the signal range.
|
| Commit |
Commits to hardware all the parameter settings associated with the task.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Initiate |
Initiates a waveform acquisition.
|
| Status |
Gets the status information about the acquisition.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
