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
