Shared Architecture and Capabilities
Both models in the series are built on a bidirectional 2-port architecture, enabling the measurement of all four S-parameters (S11, S21, S12, S22) without reconnecting the device under test. Both units offer a weight of under 7 kg (base configuration without battery), making them highly transportable for field and lab settings. They feature a 1 Hz frequency resolution, an adjustable IF/measurement bandwidth from 10 Hz to 500 kHz, and standard N-female test port connectors.
Both models support standard measurement and display formats, including Smith chart, inverted Smith chart, polar diagram, magnitude, phase, group delay, real/imaginary, and VSWR. They also support trace evaluation features such as maximum, minimum, RMS, mean, standard deviation, electrical length, and phase delay.
Model Differences and Frequency Range
The primary differentiator between the models in this family is the upper frequency limit and standard operating environments:
- Rohde & Schwarz ZVL6: Operates from 9 kHz to 6 GHz. It provides an output power range of -50 dBm to 0 dBm and runs on a Windows XP operating system.
- Rohde & Schwarz ZVL13: Extends the frequency range, covering 9 kHz to 13.6 GHz. It features a standard 6.5-inch color LCD with VGA resolution (640 × 480 pixels).
Spectrum Analysis and Expansion Options
Both instruments can be expanded to perform spectrum analysis using the R&S ZVL-K1 option (which covers 9 kHz to 6 GHz on the Rohde & Schwarz ZVL6). This option adds versatility for users who require both frequency-domain network analysis and spectral monitoring in a single instrument. Additionally, both systems support battery operation options for mobile, off-grid deployments.
Frequently asked questions
- Which options are available for cable testing and distance-to-fault measurements on the Rohde & Schwarz ZVL6?
