where <Input>
is one of A, B, D, E, for example: TriggerModeA
Possible values:
, Auto
, Relative
Manual
Default value (RST condition): Auto
Description
Auto
– Preliminary voltage measurement will be performed to find out signal voltage range and set trigger levels to best values for selected measurement function.
Depending on measurement function selected trigger levels will be automatically set to percentage values of signal voltage range:
- 10% for the main comparator, 90% for the supplementary comparator for signal edge related functions: RiseTime/FallTime/RiseFallTime/PositiveSlewRate/NegativeSlewRate
- 70% for the main comparator, 30% for the supplementary comparator for the functions with hysteresis on: Frequency/FrequencyRatio/frequencySmart/PeriodAverage/PeriodAverageSmart/TIE
- 50% for both main and supplementary comparators for all other functions
Relative
– Preliminary measurement is preformed, but you can adjust trigger levels relative to the measured signal voltage range, in percents, using RelativeTriggerLevel parameter.
Manual
– Trigger levels are set accordingly to values specified by AbsoluteTriggerLevel parameter. It is recommended to use this mode only in cases when Autoset fails to find the best settings.

Possible values:
Any floating point number representing trigger level in Volts, withing voltage measurement range. Voltage measurement range depends on

Default value (RST condition): 0
Description
Sets trigger level in volts on main comparator (if numeric index is omitted, for example: A, B, D, E) or on supplementary comparator (if numeric index is 2, for example: A2, B2, D2, E2) of the input. 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 from input (e.g. Time Interval A, A2), 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.

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.
