Keysight Technologies (Agilent HP) E5071C vs Keysight Technologies (Agilent HP) E5061B

This comparison details the differences and similarities between the Keysight Technologies (formerly Agilent HP) E5071C and E5061B ENA series vector network analyzers. While both instruments belong to the same product family, share physical power requirements, and support electronic calibration (ECal), they target distinct application spaces. The E5071C is configured for high-frequency microwave and RF development, offering broader frequency ranges up to 20 GHz and multi-port options. The E5061B serves low-frequency to RF applications, starting at 5 Hz, making it suitable for component testing, power distribution networks, and DC-DC converters. This guide highlights their distinct capabilities to assist engineers in choosing the appropriate analyzer.

Frequency Ranges and Application Focus

The primary differentiator between these two network analyzers is their operating frequency envelope. The E5071C is designed for high-frequency RF and microwave testing. Its available options support frequencies from 9 kHz up to 4.5, 6.5, or 8.5 GHz, and from 300 kHz up to 14 or 20 GHz with integrated bias tees.

In contrast, the E5061B specializes in lower-frequency ranges and RF. Standard options cover 100 kHz to 1.5 GHz or 3 GHz. The specialized LF-RF Option 3L5 extends the lower limit down to 5 Hz. This low-frequency option introduces unique hardware features like a 5 Hz to 30 MHz Gain-Phase test port with switchable 1 MΩ or 50 Ω input impedance, and a built-in sweepable DC bias source (0 to ±40 Vdc) for testing active components and power distribution networks.

Port Configurations and Impedance Options

The E5071C is highly configurable with either 2 or 4 test ports, supporting multi-port S-parameter measurements (up to S44 configurations) and expansion via the external Keysight E5092A Configurable Multiport Test Set. It uses Type-N female connectors for configurations up to 8.5 GHz and 3.5 mm male connectors for the 14 GHz and 20 GHz models.

The E5061B is restricted to a 2-port architecture. However, it offers versatility in system impedance. While the E5071C is strictly a 50 Ω nominal system, the E5061B supports both 50 Ω and 75 Ω options across its various transmission/reflection and S-parameter test sets, accommodating cable and broadcast television testing.

Measurement Capacity and UI Differences

For data-intensive testing, the E5071C offers superior processing specifications. It supports up to 100,001 measurement points per trace, 16 channels, and up to 16 data traces and 16 memory traces per channel. It also features a 10.4-inch TFT color LCD with touch-screen capability and includes built-in Visual Basic for Applications (VBA) for internal automated programming.

The E5061B offers up to 1,601 points per trace, 4 channels, and up to 4 data traces per channel. Its 10.4-inch TFT color LCD does not feature touch control. For automated control, both systems provide USB, LAN, and GPIB interfaces, but the E5071C includes a dedicated 15-pin VGA output and a 36-pin parallel Handler interface for manufacturing integration.

Frequently asked questions

Does the E5061B support multiport expansion?
No, the E5061B only supports a 2-port architecture. For multiport testing, the E5071C can be configured as a 4-port system and supports external multiport expansion using the E5092A test set.
Can both analyzers be used for time-domain measurements?
Yes, both the E5071C and the E5061B support time-domain and fault-location analysis through Option 010.
Which model is better suited for power integrity and DC-DC converter testing?
The E5061B with Option 3L5 is specifically built for this application, offering a low-frequency limit of 5 Hz, a dedicated Gain-Phase test port, and a built-in sweepable DC bias source (0 to ±40 Vdc).
