Setting and display screen.
The alarm signal, caused by wrong output power, snaps by default at -3dB of target
power and disappears when you reach the 2/3 of that.
The “Min Level Fwr Pwr Fault” additional parameter, set here, acts in an AND condition
with the standard algorithm: so, the alarm will snap when there is the first between the
two conditions “-3dB” and “Min Level Fwr Pwr Fault“, while will disappear when the
highest value between ”2/3 Ptarget“ and ”Min Level Fwr Pwr Fault+typical step related
to apparatus“ occurs.
For stand-alone devices meant to set Min Level Fwr Pwr Fault to a value greater than-
3dB, while using lower values may have meaning in N+1 systems.
By default Min Level Fwr Pwr Fault is set to the minimum value of power.
