EPM power meter at 25°C ±10°C (typical)
Switching Point
The Agilent E-series E9300 power sensors have two paths, a lower path and a
higher path. The power meter automatically selects the proper power level
path. To avoid unnecessary switching when the power level is near the switch
point, Switching Point Hysteresis has been added. This hysteresis causes
the low power path to remain selected until approximately 0.5 dB above the
switch point as the power level is increased. Above this power, the high power
path is selected. The high power path remains selected until approximately 0.5
dB below the switch point as the signal level decreases. Below this power, the
lower path is selected. 0 dBm is the switch point for the E9300/01B sensors
while the E9300/01H sensors switch at 20 dBm.
