Functions
dmm.FUNC_DIGITIZE_CURRENT
dmm.FUNC_DIGITIZE_VOLTAGE
Details
Only used when analog trigger mode is pulse.
Determines if the analog trigger occurs when the pulse is above the defined signal level or below the
defined signal level.
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_VOLTAGE
dmm.digitize.analogtrigger.mode = dmm.MODE_PULSE
dmm.digitize.analogtrigger.pulse.level = 5
dmm.digitize.analogtrigger.pulse.width = 30e-6
dmm.digitize.analogtrigger.pulse.condition = dmm.CONDITION_LESS
dmm.digitize.analogtrigger.pulse.polarity = dmm.POLARITY_BELOW
Set function to digitize voltage.
Set the analog trigger mode to pulse.
Set the analog trigger level to 5 V.
Set the analog trigger pulse width to 30 µs.
Set the condition to be detect trigger within the pulse width.
Set the trigger to occur when the pulse is below the level.
