Parameter:
<Slope> POSitive | NEGative | EITHer
POSitive
Rising edge, a positive voltage change
NEGative
Falling edge, a negative voltage change
EITHer
The rising as well as the falling edge
*RST: POSitive
TRIGger:A:LEVel<n>[:VALue]
<Level>
Sets the trigger threshold voltage for edge, width, and timeout trigger.
Suffix:
<n>
.
1..5
Selects the trigger input. 1...4 select the corresponding analog
channel, 5 is the external trigger input. The number of channels
depends on the instrument.
Parameter:
<Level> Bereich: Depends on vertical scale.
Std.-einheit: V
TRIGger:A:FINDlevel
Sets the trigger level to 50% of the signal amplitude.
Verwendung:
Ereignis
TRIGger:A:EDGE:COUPling <Coupling>
Sets the coupling for the trigger source.
Parameter:
<Coupling> DC | AC | LFReject
DC
Direct current coupling. The trigger signal remains unchanged.
AC
Alternating current coupling. A highpass filter removes the DC
offset voltage from the trigger signal.
LFReject
Sets the trigger coupling to high frequency. A 15 kHz highpass
filter removes lower frequencies from the trigger signal. Use this
mode only with very high frequency signals.
*RST: DC
Trigger
