EPM-P power meter specifications
Specifications describe the instrument’s warranted performance and apply after a 30 minute warm-up. These specifications are valid over its operating and environmental
range unless otherwise stated and after performing a zero
and calibration procedure.
Supplemental characteristics 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’.
Measurement uncertainties information can be found in,
Fundamentals of RF and Microwave Power Measurements
- Application Note 64-1, literature number 5965-6630E.
Compatibility, the EPM-P series power meters operate
with the E-series E9320 family of power sensors for peak,
average and time-gated power measurements. The EPM-P
series also operates with the existing 8480 and N8480
series, E-series CW and the E9300 range of power sensors
for average power measurements. For specifications pertaining to the 8480 and E-series CW and E9300 power sensors, please refer to the EPM Series Power Meters, E-
Series and 8480 Series Power Sensors, Technical
Specifications, literature number 5965-6382E. For specifications pertaining to the N8480 series power sensors, please
refer to the N8480 Series Thermocouple Power Sensors,
Technical Specifications, literature number 5989-9333EN.
Measurement modes, the EPM-P series power meters
have two measurement modes:
Single sensor dynamic range
E-series E9320 peak and average power sensors:
70 dB maximum (normal mode);
85 dB maximum (average only mode)
E-series CW power sensors: 90 dB
E-series E9300 average power sensors:
80 dB maximum
8480 series sensors: 50 dB maximum
N8480 series sensors: 55 dB maximum
Display units
Absolute: Watts or dBm
Relative: Percent or dB
Display resolution: Selectable resolution of 1.0,
0.1, 0.01, 0.001 dB in logarithmic mode, or 1 to 4 significant digits in linear mode.
Offset range: ±100 dB in 0.001 dB incre-
ments, to compensate for
external loss or gain
Video bandwidth: 5 MHz (set by meter and is
sensor dependent)
Note that the video bandwidth represents the ability of
the power sensor and meter to follow the power envelope
of the input signal. The power envelope of the input signal
is, in some cases, determined by the signal's modulation
bandwidth, and hence video bandwidth is sometimes
referred to as modulation bandwidth.
1. Normal mode (default mode using E9320 sensors)
for peak, average and time-related measurements,
and
2. Average only mode. This mode is primarily for
average power measurements on low-level signals,
when using E9320 sensors, and is the mode used
with 8480 and N8480 series sensors, E-series CW
sensors and E-series E9300 sensors.
Frequency range: 9 kHz to 110 GHz,
sensor dependent
Power range: -70 to +44 dBm,
sensor dependent

Video bandwidth/
dynamic range optimization
The power measurement system, comprising the sensor
and meter, has its maximum video bandwidth defined by
the E9320 sensor. To optimize the system’s dynamic range
for peak power measurements, the video bandwidth in
the meter can be set to High, Medium and Low, as
detailed in the following table. The filter video bandwidths
stated in the table are not the 3 dB bandwidths as the
video bandwidths are corrected for optimal flatness. Refer
to figures 6 to 8 for information on the sensor’s peak flatness response. A filter OFF mode is also provided.
