Rohde & Schwarz ZV Series Vector Network Analyzers

The ZV family analyzers share several core measurement characteristics designed for demanding testing environments. All three models feature 2 test ports with a 50 Ω impedance and deliver a system dynamic range of greater than 130 dB at a 10 Hz IF bandwidth. Additionally, their receiver inherent noise floors remain below -130 dBm at a 10 Hz measurement bandwidth.

Measurement speed is also consistent across the series. Each analyzer achieves normalized measurement times of less than 125 µs per point, and fully calibrated measurement times of less than 240 µs per point. Sweeps rates exceed 25 sweeps per second for 200 measurement points, with data transfer times over the IEC/IEEE (GPIB) bus taking less than 15 ms for 200 points.

While sharing performance architectures, the models differ primarily in their frequency coverage and resolution limits:

• Rohde & Schwarz ZVR offers the widest span at the low end, covering a frequency range from 10 Hz to 4 GHz. It features a frequency resolution of 10 mHz.
• Rohde & Schwarz ZVRE covers a frequency range of 20 kHz to 4 GHz, but offers a much finer frequency resolution of 10 µHz. It supports bidirectional S-parameter measurements (S11, S21, S12, S22).
• Rohde & Schwarz ZVC is designed for higher-frequency applications, extending the upper range to cover 20 kHz to 8 GHz.

Integration options vary by model. The Rohde & Schwarz ZVR and Rohde & Schwarz ZVC operate on a Windows NT platform. For automated setup, the ZVC offers the AutoKal automatic calibration feature. Manual calibration techniques for the ZVRE and ZVC include TOM, TRM, TRL, TNA, TOM-X, and TOSM.

Physically, all three units weigh 27 kg and share identical widths (435 mm) and heights (281 mm). Their depths vary slightly: the ZVRE is 580 mm deep, the ZVR is 582 mm deep, and the ZVC is 584 mm deep.
