This softkey is only available if "IFPower", "RF Power" or "BBPower" is the selected
trigger source.
Remote command:
TRIGger<n>[:SEQuence]:IFPower:HOLDoff on page 217
Trigger Hysteresis
Defines the value for the trigger hysteresis for "IF power" or "RF Power" trigger sour-
ces. The hysteresis in dB is the value the input signal must stay below the power trig-
ger level in order to allow a trigger to start the measurement. The range of the value is
between 3 dB and 50 dB with a step width of 1 dB.
Remote command:
TRIGger<n>[:SEQuence]:IFPower:HYSTeresis on page 218
Ext. Trigger Lvl
Specifies the external trigger level if trigger mode "External" is used.
Remote command:
TRIGger<n>[:SEQuence]:LEVel[:EXTernal] on page 218
Power Level
Specifies the trigger level if one of the "Power" trigger modes is set.
Remote command:
TRIGger[:SEQuence]:LEVel:POWer on page 219
Auto Lvl ← Power Level
Activates or deactivates the automatic measurement of the IF power trigger level.
"ON"
The power trigger level is measured automatically at the start of each
measurement sweep. This ensures that the power trigger level is
always set at the optimal level for obtaining accurate results but will
result in a slightly increased measurement times.
"OFF"
The power trigger level is defined manually in the "Power Level "
on page 91 field.
Remote command:
TRIGger[:SEQuence]:LEVel:POWer:AUTO on page 220
