Hysteresis
is only available when trigger mode has been selected. The
Hysteresis Norm
current setting is displayed below the label. You can use the hysteresis
Hysteresis
function to help generate a more stable trigger by preventing triggering unless
the RF power level achieves the trigger level and the additional hysteresis value. It
can be applied to both rising and falling edge trigger generation. A maximum of
3 dB hysteresis can be entered.
Rising edge
When a rising power transition triggers the power meter, the triggering system is
disabled. The power meter does not trigger again if another rising power
transition is presented. The triggering system is re-armed only when the input
power falls below a level equal to the trigger level minus the configured hysteresis
value.
Falling edge
When a falling power transition triggers the power meter, the triggering system is
disabled. The power meter does not trigger again if another falling power
transition is presented. The triggering system is rearmed only when the input
power rises above a level equal to the trigger level plus the configured hysteresis
value.
To change the setting, press and use the numeric keypad to enter the
Hysteresis
required value in the Trigger Hysteresis pop-up window to enter the new value.
