Parameters:
<dropout_time> Range: 0.00 to 10.00
*RST: 0.00
Default unit: s
Manual operation: See "Dropout" on page 53
TRIGger:EXTernal<2...2>:IMPedance <impedance>
Effective only if
TRIGger:SOURce EXTernal2
is set.
Sets termination resistance of the second external trigger input. Choose the setting
that fits the impedance of the trigger source to minimize reflections on the trigger sig-
nals.
Suffix:
<2...2>

TRIGger:HOLDoff <holdoff>
Sets the hold-off time, see Chapter 9.5.2.5, "Hold-Off Time" , on page 74 .
Parameters:
<holdoff> Range: 0.00 to 10.00
*RST: 0.00
Default unit: Seconds
Manual operation: See "Holdoff" on page 53
TRIGger:HYSTeresis <hysteresis>
Sets the hysteresis. A trigger event occurs, if the trigger level:
●
Falls below the set value on a rising slope.
●
Rises above the set value on a falling slope
Thus, you can use this setting to eliminate the effects of noise in the signal for the edge
detector of the trigger system.
Parameters:
<hysteresis> Range: 0.00 to 10.00
*RST: 0.00
Default unit: DB
Manual operation: See "Hysteresis" on page 53
