Parameter syntax: TriggerMode<Input>

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.

Example:

SYST:CONF "TriggerModeA=Auto"

Parameter syntax: AbsoluteTriggerLevel<Comparator>

where <Comparator> is one of A, A2, B, B2, D, D2, E, E2. For example: AbsoluteTriggerLevelA2

Possible values:

Any floating point number representing trigger level in Volts, withing voltage measurement range. Voltage measurement range depends on Attenuation and Preamplifier parameters. See description of Attenuation and Preamplifier parameters.

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.

Possible values: 0 … 100

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.
