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.

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.
E9300 “A” suffix sensors example:
Hysteresis causes the low power
path to remain selected until approxi-
mately –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
