E5072A ENA Series Network Analyzer 30 kHz to 4.5/ 8.5 GHz

Technical Overviews

E5072A Overview

The Keysight Technologies, Inc. E5072A ENA Series Network Analyzer is a new addition to the ENA series providing a more flexible platform with enhanced capabilities to meet your evolving measurement needs for a wide range of applications. The improved performance on the E5072A exceeds what is possible with the current RF network analyzers. The E5072A with a configurable test set provides access to the signal paths between the internal source, receivers, bridges, and the analyzer’s test ports; which improves instrument sensitivity as well as the ability to add components or peripherals for a variety of applications. The E5072A delivers new standards in versatility, speed and accuracy, and is suitable for full performance characterization of passive and active components, such as antennas, filters, and high-power amplifiers.

Carrying on the ENA series’ tradition, the E5072A has all the advantages of the industry-standard RF network analyzer (E5071C) and designed for the most demanding requirements from R&D and manufacturing. The E5072A is versatile, fast, and fully compatible, an all in one solution at an affordable price.

Versatile

Advanced features such as an extremely wide power range, high output power, and direct receiver access capability, provide flexibility to meet your changing and demanding test requirements. You can easily setup any test configuration on the E5072A, to suit your specific applications.

Application no. 1: High-power measurement

High-power signal measurements are necessary to characterize devices under real conditions. For example, there are passive components (i.e. band pass filters, couplers, isolators, or detectors) installed in front-end modules of wireless communications systems, and these are connected to the output port of power amplifiers on transmission paths. Accurate measurements of these DUTs (device under test) are required when high input is applied to the ports.

For measurements of such devices, the E5072A offers high power output from the test port up to +20 dBm. In addition, the E5072A with configurable test set capability allows you to add components in the source and receiver paths. You can add external booster amplifiers in the source path for increasing the power level to drive your DUT, attenuators or isolators can also be added in the receiver path to prevent any compression or damage of the receivers in the E5072A.

High output power up to +20 dBm

The E5072A delivers at source power level up to +20 dBm from the test port in the frequency range of 300 kHz to 1 GHz.1 The E5072A operates in a broad frequency range from 30 kHz to 4.5 GHz (Option. 245) or 8.5 GHz (Option 285) and guarantees high-power measurements with excellent impedance match with error correction. In this case, additional equipment costs such as booster amplifiers are eliminated with the E5072A

The E5072A has a 65 dB power sweep range (i.e. –49 to +16 dBm in 300 kHz to 3 GHz) with specified leveled power that allows measurements of compression characteristics on active devices without any additional amplifiers. Characterization of linear and nonlinear regions of your active devices can be achieved with a single power sweep.

Versatile

Direct receiver access to boost power

For applications that require a specific output power higher than the E5072A provides, an external amplifier is necessary in order to boost the power level to the input of the DUT. By using an external amplifier, you can physically position the amplifier closer to your DUT to reduce cables loss and achieve higher power at the DUT. The problem with using an external booster amplifier is the errors associated with temperature drift from the amplifier. These errors cannot be removed since the reference signal is measured before the booster amplifier, Also, the high reverse isolation of a booster amplifier will prevent accurate reflection measurements of the DUT.

In order to overcome the drift effect of a booster amplifier, the E5072A gives you direct access to all source and receiver paths to add external components for a variety of applications such as high-power amplifiers and, directional couplers. By using external couplers, the incident signal can be measured in the reference receiver (R1) of the E5072A after the booster amplifier rather than before, which cancels the effect of temperature drift and improves measurement uncertainty. All calibration techniques are available with this configuration, and high accuracy and long-term stability of measurements are guaranteed.
