Programmer’s Guide
3.2.2. InitHardware
Initializes device. After successful call of this function, the device can be used.
Public Shared Function InitHardware(ByRef CalibOK As Byte) As Integer
Parameters:
CalibOK – this variable will be filled with information whether the calibration
data in the device is ok
1 – calibration data are ok
0 – calibration data in the device are broken
Return value:
ERROR_OK – device was initialized successfully
ERROR_UNABLE_TO_LOAD_EM57X – unable to load em57x driver
ERROR_INIT_FAILED – device initialization failed (one of the reason can be,
that the device isn’t connected)
ERROR_FPGA_CONFIG_FAILED – FPGA initialization failed
ERROR_DK_NOT_ENABLED – the DK isn’t enabled in the connected device
ERROR_DRIVER_NOT_LOADED – the driver m570drv.dll wasn’t loaded
before this call (use LoadDriver function to load it)
3.3. Functions, that set the data acquisition parameters
3.3.1. SetTimeBase
Sets selected timebase.
Public Shared Sub SetTimeBase(ByVal ns As Integer)
Parameters:
ns – amount of nanoseconds per one division (50 samples)
Return value: -
Remark:
The list of available timebases can be obtained by GetTimeBaseList function.
3.3.2. SetRange
Sets selected range to the selected channel.
Public Shared Function SetRange(ByVal channel As Integer, ByVal mV As
Integer) As Integer
Parameters:
channel – determines channel
CHANNEL_A – channel A
CHANNEL_B – channel B
mV – determines range, which is to be set (amount of mV per division)
