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
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.
Measurement modes, the EPM-P series power meters
have two measurement modes:
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 series sensors, E-series CW sensors and
E-series E9300 sensors.

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 loga
rithmic mode, or 1 to 4 sig
nificant 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.
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 band-
width in the meter can be set to High, Medium and
Low, as detailed in the following table. The filter video
bandwidths stated i n 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.
