EPM series E4418B and E4419B power meters
Specifications
Specifications describe the instru-
ment’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
Supplemental characteristics (shown
in italics) are intended to provide
additional information, useful in
applying the instrument by giving
typical (expected), but not warrant-
ed 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, “Funda-
mentals of RF and Microwave
Power Measurements”, literature
number 5965-6380E.
Frequency range: 9 kHz to 110
GHz, sensor dependent
Power range: –70 dBm to +44 dBm
(100 pW to 25 W), sensor dependent.
Power sensors: Compatible with all
8480 series and E-series sensors
Single sensor dynamic range:
90 dB maximum (E-series sensors),
50 dB maximum ( 8480 series
sensors).
Display units:
Absolute: Watts or dBm.
Relative: Percent or dB.
Display resolution: Selectable
resolution of 1.0, 0.1, 0.01, and 0.001
dB in Log mode, or 1 to 4 digits in
linear mode.
Default resolution: 0.01 dB in log
mode, 3 digits in linear mode.
Accuracy
Instrumentation
Absolute: ±0.02 dB (log) or ±0.5%
(linear). Please add the correspond-
ing power sensor linearity percent-
age from tables 7 and 10 (for the
E-series sensors) and table 15 (for
the 8480 series sensors).
Relative: ±0.04 dB (Log) or ±1.0%
(linear). Please add the correspond-
ing power sensor linearity percent-
age from table 16 (for the 8480
series sensors).
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.
Power reference
Power output: 1.00 mW (0.0 dBm).
Factory set to ±0.7% traceable to the
U.S. National Institute of Standards
and Technology.
Accuracy: ±1.2% worst case
(±0.9% rss) for one year.
