3.3. Functions which set the generation parameters
3.3.1. SetWaveform
Sets the shape of the waveform.
Public Declare Sub SetWaveform Lib "m530drvdk.dll" (ByRef data As
Integer, ByVal datalength As Long, ByVal arbitrary As Long)
Parameters:
data – pointer to the data
datalength – length of the data in samples
arbitrary – turns arbitrary length mode on/off. In case this mode is off, the
datalength must equal to 8192.
Return value: -
Remark: It is necessary to set frequency after setting the waveform (by using the
SetFrequency function).

Sets output level.
Public Declare Sub SetLevel Lib "m530drvdk.dll" (ByVal lvl As Double)
Parametre:
lvl – indicates the voltage between quantization levels 4095 and 2048 in volts
Return value: -
3.3.3. SetOutputAttenuation
Sets output attenuation to 1:1 or 1:10.
Public Declare Sub SetOutputAttenuation Lib "m530drvdk.dll" (ByVal attn As
Long)
Parameters:
attn – indicates attenuator:
OUTPUT_ATTENUATION_1 – 1:1
OUTPUT_ATTENUATION_10 – 1:10
Return value: -
3.3.4. SetOutputOnOff
