3E4418B/9B EPM Series power meter performance characteristics 
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”, “nominal” or
“approximate”.
For information on measurement
uncertainty calculations, refer to
Application Note 64-1C, “Fundamentals 
of RF and Microwave Power 
Measurements”, literature number 
5965-6380E.
Compatible power sensors: E4410 and 
E9300 E-Series, 8480 Series and N8480 
Series average power sensors
1. National metrology institutes of member states of the Metre Convention, such as the National Institute of Standards 
and Technology in the USA, are signatories to the ComitÈ International des Poids et Mesures Mutual Recognition       
Arrangement. Further information is available from the Bureau International des Poids et Mesures, at http://www.bipm.fr/
Display resolution: Selectable
resolution of 1.0, 0.1, 0.01, and 0.001dB 
in Log mode, or 1 to 4 digits in linear 
mode
Default resolution: 0.01 dB in log
mode, 3 digits in linear mode
Measurement noise calculation:
(<45 pW x 2.75) = <121 pW
*For specifications pertaining to the N8480 Series 
power sensors, please refer to the “Agilent N8480 
Series Power Sensors Data Sheet”, literature
number 5989-9333EN.
Accuracy
Power reference
Measurement speed
Absolute: ±0.02 dB (log) or ±0.5% 
(linear). Please add the corresponding 
power sensor linearity percentage from 
Tables 6, 9 and 10 (for the E-Series 
sensors), and Table 14 (for the 8480 Series 
sensors) to asses the overall system 
accuracy.
Relative accuracy: ±0.04 dB (log) or 
±1.0% (linear). Please add the 
corresponding power sensor linearity 
percentage from Tables 6, 9 and 10 (for 
the E-Series sensors), and Table 14 (for 
the 8480 Series sensors) to asses the 
overall system accuracy.
Zero set (digital settability of zero):
Sensor dependent (refer to Table 1). For 
E-Series sensors, this specification 
applies to a zero performed when the 
sensor input is not connected to the 
POWER REF.
Zero drift of sensors: Sensor dependent, 
refer to Table 1. For E9300 sensors, refer 
to Table 11 for complete data.
Measurement noise: Sensor dependent, 
refer to Table 1 and Table 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 
sensor with the number of averages set 
at 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.
Example:
8481D power sensor, normal mode,
number of averages = 4
Frequency range: 9 kHz to 110 GHz, 
sensor dependent
Power range: –70 dBm to +44 dBm
(100 pW to 25 W), sensor dependent
Single sensor dynamic range:
90 dB maximum (E-Series sensors)
50 dB maximum (8480 Series sensors)
55 dB maximum (N8480 Series sensors)
Display units:
Absolute: Watts or dBm
Relative: Percent or dB
Power output: 1.00 mW (0.0 dBm).

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 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 power meter automatically
reads the CF data stored in the sensor
and uses it to make the corrections.
For power levels greater than 0 dBm, 
add 0.5%/dB to the calibration factor 
uncertainty specification.
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.

Figure 1. Relative mode power measurement linearity with EPM Series power meter/E-Series CW power 
sensor at 25 °C ± 5 °C (typical)
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 values. Example A illustrates 
a relative gain (amplifier measurement). 
Example B illustrates a relative loss 
(insertion loss measurement). This chart 
assumes negligible change in frequency 
and mismatch occur when transitioning
from the power level used as the 
reference to the power level being 
measured.
Example A:
P = 10(P)/10 x 1 mW
P = 10 6/10 x 1 mW
P = 3.98 mW
3% x 3.98 mW = 119.4 μW
Example B:
P = 10 (P)/10 x1 mW
P = 10 -35/10 x 1 mW
P = 316 nW
3% x 316 nW = 9.48 nW
where P = power in Watts,
and (P) = power in dBm

Effects of change in temperature on linearity 
If temperature changes and you choose 
not to re-calibrate the sensor, add the 
following power linearity error to the 
linearity specs in Table 9:
For small changes in temperature 
Typical maximum additional power 
linearity error = ±0.15%/°C
(valid after zeroing the sensor)
Figure 2 shows the typical uncertainty 
in making a relative power measurement, 
using the same power meter channel 
and same power sensor to obtain the 
reference and the measured values, and 
assumes that negligible change in 
frequency and mismatch error occur 
when transitioning from the power level 
used as the reference to the power level 
being measured.

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

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.17
E-Series average power sensor specifications (continued)
Calibration factor (CF) and
reflection coefficient (Rho)
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, for each 
individual measurement path (high power 
and low power, as shown in Table 7). 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.
