Detailed Description

The purpose of this module is to handle parallelization in the load curves procedure.

• Config example:

      driver WPSlowController
      verbosity = info
      enable = true
      InitBias = 1.543
      InitGain = 448
      InitResistance = 54
      GroupSize = 10
      SleepAfterChange = 10
      BiasStep = 0.1
      StepMode = log
      endmod
      

• Parameters
  • InitBias [ float = 0.]: Value for the partition of internal bias system. This value ranges from 0 to 10 and remains the same for the whole load curves procedure. The real bias voltage is given by InitBias/10*ExternalBias, where ExternalBias is the external bias voltage (in volts), that is different for each load curve point.
  • InitGain [ float = 448]: Initial gain
  • InitResistance [float = 54]: Initial load resistance in GOhm. Valid values are 54 and 10.86
  • GroupSize [ int = 10 ]: Number of channel to process in each load curves group
  • SleepAfterChange [ int = 10 ]: Time in seconds to wait after each change in electronics
  • BiasStep [ double = 0.1 ]: external bias step size in V (distance between curve points)
  • StepMode [ string = log ] Select the way external bias is increased (linear or logarithmic). Allowed values are "lin" and "log". This variable controls the number of steps (each of size BiasStep) that will be used to increment external bias. In case of lin, the number of step is always one. In case of log, the number of steps is given by the integer part of the current external bias in V.

Member Function Documentation

QDriver::Action MWPSlowController::Init

(

)

[virtual]

Init method.

This method reads init values from cfg, create channel groups to be processed at each iteration of the load curves sequence and initialize the QLCSlowConfigHandler singleton.

Implements QDriver.

void MWPSlowController::GroupChannels

(

const std::list< unsigned short > &

channels

)

[private]

group logical channels in subgroups

Parameters:

channels

list of all logical channels to be grouped

channels are grouped in ascending order and with the group size specified in the cfg file

void MWPSlowController::InitConfig

(

QLCSlowConfig &

conf

)

[private]

init QLCMeasConfig object with default front end settings values

Parameters:

	conf	QLCMeasConfig object to be initialized (passed by reference)
	polarity	bias polarity to be set in new configuration

QWPCommon::Step MWPSlowController::PopulateNextConfig

(

const QWPCommon::Step

step

)

[private]

determine electronics configuration for next set of measurements and apply to hardware

Returns:

false unless all curves are done and the measurement can be stopped
