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, 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
Specification, literature number 5965-6382E. For specifications pertaining to the N8480 series power
sensors, please refer to the N8480 Series Thermocouple Power Sensors, Technical Specification,
literature number 5989-9333EN.
Measurement modes, the EPM-P series power meters have two measurement modes:
•
Normal mode (default mode using E9320 sensors) for peak, average and time-related
measurements, and
•
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
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 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.
