static variable DC_CalculateDAQDataWaveLength(string device, variable dataAcqOrTP)

Calculate the required length of the DAQDataWave.

ITC Hardware:

  • The DAQDataWave length = 2^x where is the first integer large enough to contain the longest output wave plus one. X also has a minimum value of 17 to ensure sufficient time for communication with the ITC device to prevent FIFO overflow or underrun.

NI Hardware:

  • Returns stopCollectionPoint

static variable DC_MakeDAQConfigWave(string device, variable numActiveChannels)

Create the DAQConfigWave used to configure the DAQ device.

static std::tuple<WaveOrNull, WaveRefWave> DC_MakeAndGetDAQDataWave(string device, DataConfigurationResult *s, variable dataAcqOrTP)

Creates DAQDataWave; The wave that the device takes DA and TTL data from and passes AD data to for all channels.

Config all refers to configuring all the channels at once

static wave DC_SetDataScaleNIChannelWave(wave channel, variable type)

set a data scale for channel waves, this is not required for operation but allows to keep track of the scales The waves for the hardware that output data and read back data are typically in V because any other unit, like pA in current clamp mode on DAC channels is converted by the gain from pA to voltage and then by the hardware amplifier converted back from V to pA.

static wave DC_MakeNIChannelWave(string device, variable dataAcqOrTP, variable channelType, variable samplingInterval, variable index, variable dataType)

Creates a single NIChannel wave.

Config all refers to configuring all the channels at once

Wave Reference to NI Channel wave

static variable DC_MakeHelperWaves(string device, variable dataAcqOrTP)

static variable DC_CalculateChannelSizeForScaledData(string device, variable dataAcqOrTP, variable channelIndex = defaultValue)

static variable DC_InitScaledDataWave(string device, variable dataAcqOrTP)

Initialize scaledDataWave, as NI output already properly scaled data, we can prefill output channels. So in in the more time critical SCOPE_xx_UpdateOscilloscope we can optimize by only copying the ADC data over (ADC data from NI is already properly scaled by hardware)

Places channel (DA, AD, and TTL) settings data into DAQConfigWave.

static variable DC_GetDecimationFactor(string device, variable dataAcqOrTP)

Get the decimation factor for the current channel configuration.

This is the factor between the minimum sampling interval and the real. If the multiplier is taken into account depends on dataAcqOrTP.

static variable DC_CalculateLongestSweep(string device, variable dataAcqOrTP, variable channelType)
