Detailed Description

Wraps hardware connection for signal input from PMTs with NI-DAQmx.

Definition at line 20 of file InputsDAQmx.h.

Constructor & Destructor Documentation

scope::InputsDAQmx::InputsDAQmx	(	const uint32_t &	_area,
		const parameters::InputsDAQmx *const	_inputparams,
		const parameters::Scope &	_params
	)

Creates a task for PMT signal acquisition with NI DAQmx.

Configure sample timings for output tasks. With DaqTiming ReferenceClock both tasks use the onboard oscillator (empty timing source string) which is synchronized to the PXI 10MHz backplane clock used as reference clock. Read http://www.ni.com/white-paper/3615/en, "M Series Synchronization with LabVIEW and NI-DAQmx" at NI Developer Zone.
Configures the triggering for all input tasks. Since all output&input tasks have to start synchronously, the start trigger for all is the /ao/StartTrigger signal of the first area's analog output task

uint32_t scope::InputsDAQmx::StandardChunkSize ( ) const

overridevirtual

Returns

the standard size of a read chunk (per channel)

Reimplemented from scope::Inputs.

Definition at line 67 of file InputsDAQmx.cpp.

int32_t scope::InputsDAQmx::Read ( DaqChunk &  _chunk, bool &  _timedout, const double &  _timeout  )

overridevirtual

Reads one chunk of samples for one area.

Parameters

[in,out]	_chunk	chunk to fill with the read data
[out]	_timedout	true if read timed out
[in]	_timeout	timeout in seconds after which to return even if not enough samples were read

Returns

the number of samples per channel actually read
