DSP TANGO Device

Module for providing the DSP capability for the Pulsar Timing Sub-element.

class ska_pst_lmc.dsp.dsp_device.PstDsp(*args: Any, **kwargs: Any)[source]

A software TANGO device for managing the DSP component of the PST.LMC subsystem.

init_device() → None[source]

Initialise the attributes and properties of the PstDsp.

This overrides the SKABaseDevice.

create_component_manager() → PstDspComponentManager[source]

Create and return a component manager for this device.

Returns: a component manager for this device.

always_executed_hook() → None[source]: Execute call before any TANGO command is executed.

delete_device() → None[source]

Delete resources allocated in init_device.

This method allows for any memory or other resources allocated in the init_device method to be released. This method is called by the device destructor and by the device Init command.

handle_monitor_data_update(monitor_data: DspDiskMonitorData) → None[source]

Handle monitoring data.

Parameters: monitor_data (DspDiskMonitorData) – the latest monitoring data that has been reported.

diskCapacity() → int

Total capacity of the disk that DSP is writing to.

Returns: total capacity of the disk that DSP is writing to, in bytes.
Return type: int

availableDiskSpace() → int

Available space on the disk that DSP is writing to.

Returns: available space on the disk that DSP is writing to, in bytes.
Return type: int

diskUsedBytes() → int

Get sed space on the disk that DSP is writing to.

This is diskCapacity - availableDiskSpace.

Returns: use space on the disk that DSP is writing to, in bytes.
Return type: int

diskUsedPercentage() → float

Get used space on the disk that DSP is writing to.

This is 100.0 * (diskCapacity - availableDiskSpace)/availableDiskSpace.

Returns: use space on the disk that DSP is writing to, in bytes.
Return type: float

dataRecordRate() → float

Get current rate of writing to the disk.

Returns: use space on the disk that DSP is writing to, in bytes.
Return type: float

dataRecorded() → int

Get number of bytes written during scan.

Returns: number of bytes written during scan.
Return type: int

availableRecordingTime() → float

Get current rate of writing to the disk.

Returns: use space on the disk that DSP is writing to, in bytes.
Return type: float

subbandDataRecorded() → List[int]

Get the bytes per written for each subband.

Returns: the bytes per written for each subband.
Return type: List[int]

subbandDataRecordRate() → List[float]

Get the current rate of writing to disk for each subband.

Returns: the current rate of writing to disk for each subband.
Return type: List[float]
