Development kit for DATAMAN 570 series
Programmer’s Guide
level – determines the digital shielding factor (valid values are: 2, 4, 8, 16, 32
and 64)
Return value: -
Remark:
In order to make the digital shielding work correctly, it is necessary to have a stable
and well triggered signal on the input. Digital shielding prolongs the oscilloscope
response to the signal change (the higher the factor the longer the response).
3.4. Data acqusition functions
3.4.1. StartMeasurement
Starts/restarts data acquisition.
Public Shared Sub StartMeasurement()
Parameters: -
Return value: -
3.4.2. IsDataReady
Returns the data acquisition status.
Public Shared Function IsDataReady() As Integer
Parameters: -
Return value:
Indicates data acquisition status. It is one of following constants:
DATA_NOT_TRIGGERED – valid trigger event hasn’t occured
DATA_TRIGGERED – the acquisition is triggered and is in progress
DATA_READY – the acquisition is finished, data are prepared to be
transferred to computer. This transfer can be done by GetData function.
DATA_ERROR – the communication with device is broken, it is not
possible to determine acquisition status
3.4.3. GetReconstructionPercentage
Returns ratio of the measured data to measured data + interpolated data.
Public Shared Sub GetReconstructionPercentage(ByRef channelA As Integer,
ByRef channelB As Integer)
Parameters:
channelA – amount of channel A, that was measured (percentage)
channelB – amount of channel B, that was measured (percentage)
