Programmer’s Guide
channel – determines channel
CHANNEL_A – channel A
CHANNEL_B – channel B
mV – determines range, which is to be set (amount of mV per division)
Return value:
The vertical shift which must be set to keep the position of 0V at the same place.
Remark:
If it is necessary to keep the 0V position on the screen intact, it is necessary to set the
vertical shift using function SetVert to the return value.
3.3.3. SetCoupling
Sets selected coupling on the channel.
Public Declare Sub SetCoupling Lib "m770drvdk.dll" (ByVal channel As
Long, ByVal coupling As Long)
Parameters:
channel – determines channel
CHANNEL_A – channel A
CHANNEL_B – channel B
coupling – determines coupling
COUPLING_AC – AC coupling
COUPLING_DC – DC coupling
Return value: -
3.3.4. SetVert
Sets specified shift to the selected channel.
Public Declare Function SetVert Lib "m770drvdk.dll" (ByVal channel As
Long, ByVal shift As Long) As Long
Parameters:
channel – determines channel
CHANNEL_A – channel A
CHANNEL_B – channel B
shift – shift value from 0 to 4095, where 0 moves the waveform maximally
downwards and 4095 moves the waveform maximally upwards
Return value:
Position on the screen (quantization level), which corresponds with 0V.
3.3.5. SetTriggerLevel
Sets threshold on the selected source.
