Rohde & Schwarz ZNLE3 Vector Network Analyzer

Overview

The Rohde & Schwarz ZNLE3 is a compact two-port vector network analyzer designed for bidirectional S-parameter measurements on passive RF and microwave components. The analyzer features a 10.1" WXGA touchscreen with an intuitive drag-and-drop user interface, allowing configuration and measurement without requiring an external PC. With a frequency range of 1 MHz to 3 GHz and dynamic range up to 120 dB, it delivers accurate and repeatable measurements across its operating band.

As a standalone instrument with integrated Windows 10 PC platform and solid-state storage, the ZNLE3 provides fast boot time, reliable operation, and low trace noise of 0.001 dB typical at 10 kHz bandwidth. The built-in calibration wizard supports both manual and automatic calibration units, making it ideal for production and R&D environments where speed and accuracy are essential.
