ENA Series for RF and LF-RF Characterization
The ENA series is Keysight's primary family for cost-effective, high-speed RF network analysis. The E5071C is a standard benchtop platform, configurable with 2 or 4 ports and offering frequency options from 9 kHz up to 20 GHz. For newer designs, the E5080A serves as its successor, expanding measurement capabilities with a system dynamic range up to 135 dB and an IF bandwidth ranging from 1 Hz to 3 MHz.
For specialized RF needs, the E5061B covers frequencies from 100 kHz up to 3 GHz, with an LF-RF Option (3L5) that extends its coverage down to 5 Hz for low-frequency testing. The E5063A provides a streamlined, 2-port option with coverage up to 18 GHz, optimized for standard passive component verification.
PNA and PNA-X Series for Advanced Microwave Analysis
For high-frequency microwave applications, the PNA and PNA-X series represent Keysight's premier-performance tier. The standard PNA series (including the N5222A and N5225A) operates up to 50 GHz and provides multi-port S-parameter characterization. The flagship PNA-X series, which includes the N5242A, N5242B, and N5245B, functions as a highly integrated microwave test engine. Available in 2- or 4-port configurations, PNA-X analyzers can be equipped with up to two internal sources, internal combiners, and signal-routing switches to run complex tests—such as noise figure, gain compression, and intermodulation distortion (IMD)—using a single connection.
The PNA-L series (including the N5230A, N5230C, and N5232A) delivers a mid-range microwave option, offering general-purpose S-parameter analysis up to 50 GHz.
Legacy and Specialty Instruments
Many laboratories continue to utilize legacy Agilent and HP platforms. The 8753 series (such as the 8753D, 8753E, and 8753ES) covers the RF range up to 6 GHz, while the 8720 and 8722 series (including the 8720D, 8722D, and 8722ES) span microwave frequencies up to 40 GHz. These legacy instruments feature integrated S-parameter test sets and robust physical interfaces.
Specialty platforms include combination analyzers such as the 4395A and 4396B, which consolidate vector network, spectrum, and impedance analyzer capabilities into a single system. The modular 8510C analyzer supports custom millimeter-wave and coaxial configurations, whereas the 8757D operates as a scalar network analyzer. For remote or field installations, the handheld N9923A FieldFox provides fully portable vector network measurements up to 6 GHz.
Frequently asked questions
- What are the main performance advantages of the E5080A over the E5071C?
- The E5080A is designed as the next-generation replacement for the E5071C. It improves measurement flexibility with a maximum dynamic range of 135 dB (compared to the E5071C) and a wider IF bandwidth range of 1 Hz to 3 MHz. It also features a larger 12.1-inch WXGA touchscreen and a removable solid-state drive.
- How does the PNA-L series differ from the PNA-X series?
- The PNA-L series, such as the N5230C or N5232A, is a mid-range platform with one internal source, optimized for passive components and basic active testing. The flagship PNA-X series, such as the N5242B, is a highly integrated engine offering up to two internal sources, optional built-in combiners, and dedicated hardware for active device tests like noise figure and spectrum analysis.
- Which calibration module should be used for microwave measurements up to 67 GHz?
- The N4694A is a 2-port electronic calibration (ECal) module that operates from 10 MHz to 67 GHz. It features 1.85 mm test port connectors and a USB interface to automate the calibration process on compatible Keysight VNAs.
