Switching Point
The Agilent E-series E9300 power sensors have two paths, a low power path
covering -60 dBm to -10 dBm, and a high power path covering -10 dBm to
+20 dBm. The power meter automatically selects the proper power level path.
To avoid unnecessary switching when the power level is near the -10 dBm
point, Switching Point Hysteresis has been added. This hysteresis causes
the low power path to remain selected until approximately -9.5 dBm as the
power level is increased, above this power the high power path is selected.The
high power path remains selected until approximately -10.5 dBm as the signal
level decreases, below this power the low power path is selected.
