Sets relative trigger levels in percents relative to signal voltage range, for main and supplementary comparators.
Parameter syntax: RelativeTriggerLevel<Comparator>
where <Comparator> is one of A, A2, B, B2, D, D2, E, E2. For example: RelativeTriggerLevelB2
Possible values: 0 … 100
Default value (RST condition):
70 for the main comparators
30 for the supplementary comparators
Description
Sets trigger level on main (if comparator index is omitted, e.g. just A) or on supplementary comparator (if comparator index is 2, e.g. A2) of input in percents relative to measured signal voltage range. 0% corresponds to signal min value and 100% corresponds to signal max value. Main comparator is used for all measurements performed on input, generating events to internal measurement core whenever signal crosses set trigger level. Supplementary comparator can be selected explicitly for some measurements generating independent events to internal measurement core whenever signal crosses set trigger level. Otherwise it is used implicitly for frequency average and period average measurements (to assure wide hysteresis), for Rise & Fall Time and Slew Rate.
