E4418B/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

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

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).
Factory set to ±0.4% traceable to the
National Physical Laboratory (NPL),

.
Accuracy: For two years:
±0.5% (23 ± 3 °C)
±0.6% (25 ± 10 °C)
±0.9% (0 to 55 °C)
Frequency: 50 MHz nominal
SWR: 1.06 maximum
(1.08 maximum for Option 003)
Connector type: Type-N (f), 50
Three measurement speed modes,
over the GPIB, are available as shown,
along with the typical maximum
measurement speed for each mode.
With E4418B power meter
Normal: 20 readings/second
x2: 40 readings/second
Fast: 200 readings/second
With E4419B power meter
Measurement speed is reduced, for
example, with both channels in FAST
mode, the typical maximum
measurement speed is 100 readings
/second.
Fast mode is for E-Series sensors only.
Maximum measurement speed is
obtained using binary output and in free
run trigger mode.
