E-Series 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.

Example with E9300 “A” sufﬁx
sensors:

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

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.
