The Keysight E4416A and E4417A are EPM-P series power meters that operate with the E-series E9320 family of peak and average power sensors for peak, average, and time-gated power measurements. The E4416A is a single-channel instrument, while the E4417A provides two measurement channels. In addition to the E9320 sensors, the EPM-P meters also operate with the 8480 and N8480 series, E-series CW, and the E9300 range of power sensors for average power measurements. Two measurement modes are provided: Normal mode, the default when using E9320 sensors, for peak, average, and time-related measurements; and Average only mode, intended primarily for average power measurements on low-level signals and used with the 8480, N8480, E-series CW, and E9300 sensors.

A power meter quantifies the RF or microwave power present at its sensor input and displays the result in absolute units (watts or dBm) or relative units (percent or dB). The EPM-P series adds predefined setups for common wireless standards — GSM900, EDGE, NADC, iDEN, Bluetooth, IS-95 CDMA, W-CDMA, and cdma2000 — simplifying configuration for those measurement tasks. With a 20 Msample/second continuous sampling rate and a 5 MHz video bandwidth, the system follows the power envelope of an input signal; because that envelope is, in some cases, set by the signal's modulation bandwidth, the video bandwidth is sometimes referred to as modulation bandwidth.

ValueTronics holds and stocks its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments offered here are inventory we keep on hand rather than items sourced after the fact. That combination lets engineers and labs source the right power meter and sensor configuration with confidence in both condition and availability.

Brand Heritage

Keysight Technologies traces its roots to Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999 and then established as the independent Keysight Technologies in 2014.

Compare Other Models in This Series

The EPM-P series pairs the E4416A and E4417A power meters with the E-series E9320 family of peak and average power sensors. The E4416A is a single-channel meter and the E4417A is a dual-channel meter; both share the same measurement modes, interfaces, and reference architecture. Measurement capability — frequency coverage, power range, and dynamic range — depends on which sensor is connected.

The E9320 sensors come in six models that differ in frequency coverage and video bandwidth. The E9321A, E9322A, and E9323A cover 50 MHz to 6 GHz, while the E9325A, E9326A, and E9327A cover 50 MHz to 18 GHz, with video bandwidths of 300 kHz, 1.5 MHz, and 5 MHz spanning the pairs.

Each new model below is its own dedicated product page with condition-matched pricing. Select the meter or sensor that fits your application, and review that page for its specific configuration and availability.

The primary meter difference is channel count: the E4416A provides a single measurement channel, while the E4417A provides two channels and adds a second recorder output for channel B. Net weight differs slightly (approximately 4.0 kg versus 4.1 kg), and the E4417A ships with two E9288A sensor cables versus one for the E4416A.

Across the E9320 sensors, the differences are frequency range and video bandwidth: the E9321A/E9322A/E9323A reach 6 GHz and the E9325A/E9326A/E9327A reach 18 GHz, with video bandwidths of 300 kHz, 1.5 MHz, and 5 MHz respectively. The comparison table that follows details the per-model frequency range, video bandwidth, and power range.

Product Core & Specifications

Important: E9320 power sensors must be used with an E9288A, E9288B, or E9288C sensor cable.

Important: A compatible power sensor is required to make measurements and is ordered separately — the EPM-P power meter's standard-shipped accessories include only the power sensor cable, power cord and manuals (no sensor). The EPM-P series operates with the E-series E9320 family for peak/average measurements and with the 8480, N8480, E-series CW and E9300 sensors for average power measurements.

Important: The E9288A, B and C sensor cables will also operate with 8480, N8480 and E-series power sensors.

Important: Rise and fall time specifications are only valid when used with the E9288A sensor cable (1.5 meters).

Important: Calibration service options (R-50C-011-3 / R-50C-011-5) are not available in all countries.

Important: To preserve the EMC performance of the product, any cable which becomes worn or damaged must be replaced with the same type and specification.

ValueTronics supplies both new and used test and measurement equipment.
