E-Series E9300 Average Power Sensor Specifications (Continued)
Switch point data
The E9300 power sensors have two paths as shown in Table 7� 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�
E9300 “A” suffix sensors example:
– 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 will be selected� The high power path will remain selected until approximately –10�5 dBm is reached as
the signal level decreases, below this power the low power path will be selected�
Switching point linearity:
– Typically = ± 0�5% (= ± 0�02 dB)
Switching point hysteresis:
– 0�5 dB typical
