E-Series E9300 Average Power Sensors
Switch Point Data:
The E9300 power sensors have two paths, a low power path covers: -60 to -10 dBm ("A" suffix sensors), -30 to +20 dBm
("B" suffix sensors), and -50 to 0 dBm ("H" suffix sensors). The high power path covers: -10 to +20 dBm ("A" suffix sen-
sors), +20 to +44 dBm ("B" suffix sensors), and 0 to +30 dBm ("H" suffix sensors). 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

1. RH is the abbreviation for Relative Humidity.
2. Within 1 hour after zero set, at a constant temperature, after a 24-hour warm-up of the power meter with power sensor connected.
3. The number of averages at 16 for Normal mode and 32 for x2 mode, at a constant temperature, measured over a one minute interval and two standard deviations.
