Specifications describe the instrument’s warranted performance and apply after a 30 minute warm-up� These specifications are valid
over its operating/environmental range unless otherwise stated and after performing a zero and calibration procedure�
Supplemental characteristics (shown in italics) are intended to provide additional information, useful in applying the instrument by
giving typical (expected), but not warranted performance parameters� These characteristics are shown in italics or labeled as “typical,”

Default resolution 0.01 dB in logarithmic mode or three digits in linear mode
Accuracy
Absolute accuracy ± 0.02 dB (Logarithmic) or ± 0.5% (Linear). Please add the corresponding power sensor linearity percentage from Tables
6, 9 and 10 (for the E-Series sensors), Table 14 (for the 8480 series sensors) and Table 16 (for N8480 sensors) to assess
the overall system accuracy.
Relative accuracy ± 0.04 dB (Logarithmic) or ± 1.0% (Linear). Please add the corresponding power sensor linearity percentage from the
mentioned tables above to assess the overall system accuracy.
Zero set (digital settability of
zero)
0.0000175% (meter only)
Power sensor dependent (refer Table 1), this specification applies when zeroing is performed with sensor input
disconnected from the POWER REF.
Zero drift of sensors 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

Fast mode is for Keysight E-Series power sensors only.
Maximum measurement speed is obtained using binary output in free run trigger mode.

Power meter functions
Accessed by key entry Either hard keys, or soft key menu, and programmable
Zero Zeros the meter. (Power reference calibrator is switched off during zeroing.)
Cal Calibrates the meter using internal (power reference calibrator) or external source. Reference cal factor settable from 1%
to 150%, in 0.1% increments.
Frequency Entered frequency range is used to interpolate the calibration factors table. Frequency range from 1 kHz to 999.9 GHz.
Also settable in 1 kHz steps.
Cal factor Sets the calibration factor for the meter. Range: 1% to 150%, in 0.1% increments.
Relative Displays all successive measurements relative to the last displayed value
Offset Allows power measurements to be offset by –100 dB to +100 dB, settable in 0.001 dB increments, to compensate for
external loss or gain
Save/recall Store up to 10 instrument states via the save/recall menu
dBm/W Selectable units of either Watts or dBm in absolute power; or percent or dB for relative measurements
Filter (averaging) Selectable from 1 to 1024. Auto-averaging provides automatic noise compensation.
Duty cycle Duty cycle values between 0.001% to 99.999%, in 0.001% increments, can be entered to display a peak power
representation of measured power. The following equation is used to calculate the displayed peak power value: peak power
= measured power/duty cycle.
Sensor cal tables Selects cal factor versus frequency tables corresponding to specified sensors
Limits High and low limits can be set in the range –150.000 to +230.000 dBm, in 0.001 dBm increments
Preset default values dBm mode, rel off, power reference off, duty cycle off, offset off, frequency 50 MHz, AUTO average, free run, AUTO range

Display Color display with selectable single and split screen formats are available. A quasi-analog display is available for peaking
measurements. The dual channel power meter can simultaneously display any two configurations of A, B, A/B, B/A, A-B,
B-A and relative. With the optional USB ports, additional dual channel (C & D), adds up to total 4-channels measurement
display.

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:
SWR = 1 + Rho/1 – Rho�
Maximum uncertainties of the CF data are
listed in Table 5a, for the E4412A power
sensor, and Table 5b for the E4413A power
sensor� The uncertainty analysis for the
calibration of the sensors was done in
accordance with the ISO/TAG4 Guide�
The uncertainty data reported on the
calibration certificate is the expanded
uncertainty with a 95% confidence level
and a coverage factor of 2�

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)�

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)
