Detailed Description

A DaqChunk contains data from all channels sequentially.

First perchannel samples of channel 0, then perchannel samples of channel 1 etc etc...

Member Typedef Documentation

typedef std::vector<uint16_t>::iterator scope::DaqChunk::iterator

Iterator over the data vector.

Constructor & Destructor Documentation

scope::DaqChunk::DaqChunk	(	const uint32_t &	_perchannel,
		const uint32_t &	_nchannels,
		const uint32_t &	_area
	)

Parameters

[in]	_perchannel	number of samples the chunk should contain per channel
[in]	_nchannels	number of channels in the chunk (total number of samples is thus _perchannel*_nchannels)
[in]	_area	sets the area value for the channel

Definition at line 7 of file DaqChunk.cpp.

virtual scope::DaqChunk::~DaqChunk ( )

inlinevirtual

Virtual destructor here, to be prepared for derived classes.

Definition at line 37 of file DaqChunk.h.

Member Function Documentation

void scope::DaqChunk::Downsample ( const uint32_t &  _factor )

virtual

Downsamples by averaging _factor samples.

Replaces every _factor samples by their average. The chunk does shrink that way and perchannel is adjusted.

Parameters

[in]

_factor

downsampling factor

Definition at line 19 of file DaqChunk.cpp.

void scope::DaqChunk::Scale ( const double &  _factor )

virtual

Multiplies every sample by _factor.

Definition at line 46 of file DaqChunk.cpp.

Member Data Documentation

const uint32_t scope::DaqChunk::area

protected

Area of the DaqChunk.

Definition at line 13 of file DaqChunk.h.

const uint32_t scope::DaqChunk::nchannels

protected

Number of channels in that area/DaqChunk.

Definition at line 16 of file DaqChunk.h.

uint32_t scope::DaqChunk::perchannel

protected

Number of samples per channel.

Definition at line 19 of file DaqChunk.h.

std::vector<uint16_t> scope::DaqChunk::data

The data vector.

Definition at line 26 of file DaqChunk.h.

std::vector<iterator> scope::DaqChunk::lastmapped

Iterators to positions that was last mapped.

One for every channel.
