Set absolute trigger levels for main and supplementary comparators
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
and Attenuation
parameters. See description of Preamplifier
and Attenuation
parameters.Preamplifier
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.
Example:
SEND → SYST:CONF "TriggerModeA=Manual; AbsoluteTriggerLevelA=-2.5; AbsoluteTriggerLevelA2=2.5; TriggerModeB=Manual; AbsoluteTriggerLevelB=0; AbsoluteTriggerLevelB2=1.35"
