Keysight ENA Series Vector Network Analyzers

For applications requiring high measurement speed and multi-port complexity, the upper-tier ENA models provide deep analytical capabilities. The E5071C is an industry-standard RF network analyzer covering 9 kHz up to 20 GHz with 2-port or 4-port configurations. It features a 10.4-inch touchscreen and optional time domain analysis (Option 010). The E5071B operates from 300 kHz to 8.5 GHz, supporting integrated 2-, 3-, or 4-port systems and offering an integrated Visual Basic for Applications (VBA) programming environment.

Representing the next generation, the E5080A and E5080B models integrate a larger 12.1-inch WXGA touchscreen and updated computing platforms. The E5080A is designed as the next-generation successor to the E5071C, covering 9 kHz to 9 GHz with a system dynamic range up to 135 dB. The E5080B scales significantly higher, covering 9 kHz to 53 GHz, and utilizes a Windows 10 operating system alongside a typical system dynamic range up to 152 dB. The E5080B also supports advanced analysis options such as spectrum analysis, noise figure, and pulsed-RF.

When testing standard components or specialized low-frequency devices, the ENA series offers tailored configurations. The E5061B stands out for its versatility, featuring a frequency option (Option 3L5) that covers 5 Hz to 3 GHz, allowing users to analyze both low-frequency and RF parameters. This model includes a built-in DC bias source (0 to ±40 Vdc) and a dedicated gain-phase test port with switchable 1 MΩ / 50 Ω input impedance.

For cost-sensitive applications, the ENA-L and basic ENA models deliver essential S-parameter capabilities:

• E5063A: A 2-port analyzer scaling from 100 kHz up to 18 GHz, offering standard 50 Ω Type-N connectors, optional time domain analysis, and a system dynamic range of 117 dB.
• E5062A: A general-purpose 300 kHz to 3 GHz analyzer available with either 50 Ω or 75 Ω test port impedance options, supporting up to 4 independent channels and 4 traces per channel.
• E5061A: A basic 300 kHz to 1.5 GHz analyzer configured with either transmission/reflection (T/R) or full 2-port S-parameter test sets, matching the 50 Ω or 75 Ω impedance options of the E5062A.

Across the series, precise calibration and data processing are supported to minimize test uncertainty. The E5071C delivers a low trace noise of 0.004 dB rms (at 70 kHz IFBW), while the E5071B reaches 0.001 dB rms trace noise. Multiple calibration methods are supported, including mechanical calibration, Unknown Thru, and Electronic Calibration (ECal) modules via USB.

Integration with automatic test environments is facilitated by diverse interfaces. The instruments feature LAN, USB, and GPIB connectivity for automation. Legacy storage formats, such as the built-in floppy disk drive in the E5071B, contrast with modern solid-state drives (SSD) used in the E5080A and E5080B, allowing test laboratories to match hardware with their active infrastructure and IT security requirements.
