Development kit for DATAMAN 520 series
Programmer’s Guide
WCD_VERY_HIGH_SENSITIVITY = 8
WCD_HIGH_SENSITIVITY = 12
WCD_MEDIUM_SENSITIVITY = 16
WCD_LOW_SENSITIVITY = 20
Return Value:
ERROR_OK – Function call successfuly completed
ERROR_DEVELOPMENT_KIT_NOT_ENABLED – DK can not be used with
connected device (DK was not purchased)
ERROR_USB_COMMUNICATION_FAILED
– USB communication failed
SetDigitalShielding
Enables digital shielding and sets its level on channel specified by
ChannelSelector.
Declaration:
typedef _export _stdcall int (*fSetDigitalShielding) (bool
DigitalShieldingActive, int DigitalShieldingLevel, int ChannelSelector);
TSetDigitalShielding = function (DigitalShieldingActive: Boolean;
DigitalShieldingLevel: Integer;ChannelSelector: Integer): Integer; stdcall;
Public Declare Function SetDigitalShielding Lib "VBDevKit52X.dll" (ByVal
DigitalShieldingActive As Boolean, ByVal DigitalShieldingLevel As Long, ByVal
ChannelSelector As Long) As Long
Parameters:
DigitalShieldingActive – True activates digital shielding, false deactivates it
DigitalShieldingLevel – Desired level of digital shielding <2..64>. We
recommend to set value 4 for most of measurements.
ChannelSelector – Valid values are
constants CHANNEL_A or CHANNEL_B
Return Value:
ERROR_OK – Function call successfuly completed
ERROR_DEVELOPMENT_KIT_NOT_ENABLED – DK can not be used with
connected device (DK was not purchased)
ERROR_USB_COMMUNICATION_FAILED
– USB communication failed
Note:
The higher digital shielding level is entered, the slower oscilloscope reflects
signal change.
SetShapePrediction
Activates the shape prediction for sampling mode.
Declaration:
Typedef _export _stdcall int (*fSetShapePrediction) (bool ShapePrediction);
TSetShapePrediction = function (ShapePrediction: Boolean): Integer; stdcall;
Public Declare Function SetShapePrediction Lib "VBDevKit52X.dll" (ByVal
ShapePrediction As Boolean) As Long
