# Keysight E9327A E-Series E9320 Peak and Average Power Sensor, 50 MHz to 18 GHz, 5 MHz Video Bandwidth # Keysight E9327A E-Series E9320 Peak and Average Power Sensor, 50 MHz to 18 GHz, 5 MHz Video Bandwidth ## Key Features At A Glance - Peak, average, and time-gated power measurement using the E-series E9320 sensor family in Normal and Average-only modes - Frequency coverage from 9 kHz to 110 GHz and power range of –70 to +44 dBm, sensor dependent - GPIB (IEEE 488.2), RS-232, and RS-422 serial interfaces supplied as standard for ATE integration - SCPI command language with 20 Msample/s continuous sampling for automated measurement systems - Available in single-channel (E4416A) and dual-channel (E4417A) configurations - Predefined setups for GSM900, EDGE, NADC, iDEN, Bluetooth, IS-95 CDMA, W-CDMA, and cdma2000 standards - Internal 1 mW (0.0 dBm) 50 MHz power reference, factory set to ±0.5% traceable to the NPL - Operates with E9320, E-series CW, E9300, 8480, and N8480 series power sensors 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.
