Power sensor dependent (refer Table 1), this specification applies when zeroing is performed with sensor input
disconnected from the POWER REF.
This parameter is also called long term stability and is the change in the power meter indication over a long time (within
one hour) at a constant temperature after a 24-hour warm-up of the power meter. Sensor dependent, refer to Table 1.
For E9300 sensors, refer to Table 11 for complete data.
Measurement noise
Sensor dependent, refer to Tables 1 and 2. For E9300 sensors, refer to Table 11 for complete data
Effects of averaging on noise
Averaging over 1 to 1024 readings is available for reducing noise. Table 1 provides the measurement noise for a
particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the “Noise
Multiplier” for the appropriate mode (normal or x2) and number of averages to determine the total measurement noise
value.
For example: For a Keysight 8481D power sensor in normal mode with the number of averages set to 4, the
measurement noise is equal to: (< 45 pW x 2.75) = < 124 pW

E-Series Power Sensor Specifications
The E-Series of power sensors have their calibration factors stored in EEPROM and operate over a wide dynamic range. They are
designed for use with the EPM Series of power meters and two classes of sensors are available:
–– CW power sensors (E4412A and E4413A)
–– Average power sensors (E9300 sensors)

Calibration factor (CF) and
reflection coefficient (Rho)
Calibration factor and reflection
coefficient data are provided at 1 GHz
increments on a data sheet included with
the power sensor. This data is unique
to each sensor. If you have more than
one sensor, match the serial number on
the data sheet with the serial number
on the power sensor you are using. The
CF corrects for the frequency response
of the sensor. The EPM power meter
automatically reads the CF data stored
in the sensor and uses it to make the
corrections.
Reflection coefficient (Rho) relates to the
SWR according to the following formula:

Table 6. E4410 Series power linearity specification.
The chart in Figure 1 shows the typical
uncertainty in making a relative power
measurement, using the same power
meter channel and the same power sensor
to obtain the reference and the measured

Effects of change in temperature on linearity
Note: If the temperature changes after calibration and you choose not to re-calibrate the sensor, the following additional power
linearity error should be added to the linearity specs in Table 9.
For small changes in temperature: The typical maximum additional power linearity error due to small temperature change after
calibration is ± 0.15%/°C (valid after zeroing the sensor).
For large changes in temperature: refer to Table 10.

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

Calibration factor and reflection
coefficient data are provided at frequency
intervals on a data sheet included with the
power sensor. This data is unique to each
sensor. If you have more than one sensor,
match the serial number on the certificate
of calibration (CoC) with the serial number
on the power sensor you are using. The
CF corrects for the frequency response of
the sensor. The EPM Series power meter
automatically reads the CF data stored
in the sensor and uses it to make the
corrections.
Reflection coefficient (Rho) relates to the
SWR according to the following formula:
SWR = (1 + Rho)/(1 – Rho)
Maximum uncertainties of the CF data
are listed in Tables 12a and 12b. As the
E-Series E9300 power sensors have two
independent measurement paths (high and
low power paths), there are two calibration
factor uncertainty tables. The uncertainty
analysis for the calibration of the sensors
was done in accordance with the ISO
Guide. The uncertainty data reported on
the calibration certificate is the expanded
uncertainty with a 95% confidence level
and a coverage factor of 2.

N8480 Series Thermocouple Power Sensor Specifications
The N8480 Series power sensors (excluding Option CFT) measure power levels from –35 to +44 dBm (316 nW to 25.1 W), at
frequencies from 100 kHz to 50 GHz and have two independent power measurement range (upper and lower range).
Meanwhile, the N8480 sensors with Option CFT only measure power levels from –30 to +44 dBm (1 μW to 25.1 W) in single
range. Similar to the E‑Series power sensors, the N8480 Series power sensors are also equipped with EEPROM to store sensor’s
characteristics such as model number, serial number, linearity, temperature compensation, calibration factor, and so forth.
This feature ensures the correct calibration data is applied by any compatible power meter connected with N8480 Series power sensor,
and to ensure the accuracy of the measurements.

Switch point data
Switching point is applicable for standard N8480 Series power sensors only.
The N8480 Series power sensors have two power measurement ranges; a lower range
and upper range. The power meter automatically selects the proper power range. To avoid
unnecessary switching when the power level is near switching point, a Switching Point
Hysteresis has been added.
Switching point hysteresis: 0.5 dB typical
Example of switching point hysteresis on N8481/2H power sensors, this hysteresis causes the
lower range to remain selected until approximately 17.5 dBm as the power level is increased,
above this power the upper range is selected.
The upper range remains selected until approximately 16.5 dBm as the signal level decreases,
below this power the lower range is selected.
For more detailed specifications, refer to N8480 Series Thermocouple Power Sensors, data
sheet (5989-9333EN).
