R&S®ZVT Vector Network Analyzers

• Multiport measurements, avoiding any time loss due to matrix control
• Flexible configuration of test ports for balanced and single-ended measurements
• True differential measurements and coherent signal generation
• Enhanced performance by parallel measurements on several DUTs
• Multichannel receiver with simultaneous sampling of channels, e.g. for phase measurements on antenna arrays
• Automatic calibration units
• Point-in-pulse and pulse profile measurements with up to 16 receivers
• Up to 3 (R&S^®ZVT20) or 4 (R&S^®ZVT8) internal sources for flexible and efficient measurements on active devices, such as (double) converting transmitters, receivers etc

The R&S^®ZVT8/R&S^®ZVT20 from Rohde & Schwarz is the first true eight-port/six-port vector network analyzer with a frequency range from 300 kHz to 8 GHz/10 MHz to 20 GHz. The R&S^®ZVT8 contains up to four internal generators and up to 16 receivers. The R&S^®ZVT20 includes up to three internal generators and up to 12 receivers. This unique concept with one generator per two test ports makes the R&S^®ZVT ideal for intermodulation measurements, even on mixers, (true) differential balanced measurements, multireceiver measurements with antennas or high throughput and efficiency in production.

The R&S^®ZVT features the same comprehensive functionality and range of options as the R&S^®ZVA. Plus, it offers a larger number of ports, i.e. generators and receivers. All applications described here for the R&S^®ZVA also apply to the R&S^®ZVT. The instrument offers excellent network analyzer characteristics and comprehensive measurement capabilities for two- to eight-port applications, irrespective of the number of test ports:

• Extremely fast and accurate measurements on multiport DUTs
  • No delay caused by switch matrix control
  • Greater stability, reproducibility, and flexibility
• Measurements on balanced DUTs
  • Virtual differential measurement mode (sequential stimulation of single-ended ports, standard mode)
  • True differential measurement mode:
    With eight test ports (four internal sources), up to four true differential signals can be generated and applied to the DUT ports simultaneously
• Unique performance for measurements on amplifiers, mixers, receivers, frontends, etc.:
  • Arbitrary frequency and power settings for internal generators and receivers as well as external generators
  • Measurement of conversion loss, return loss, leakage, etc., of mixers
  • Intermodulation and hot S-parameter measurements on amplifiers
  • Intermodulation measurements on mixers by means of a single instrument
  • Measurements on double-converting DUTs, with the RF, LO1, and LO2 signals delivered by a single unit
• Pulsed measurements on amplifiers, mixers, frontends, etc. (for details see "Applications" and "Options" tabs)
  • Frequency- and power-swept point-in-pulse measurements
  • Pulse profile measurements with 12.5 ns resolution on pulses, double pulses and pulse trains with a width smaller than 50 ns; recording time up to 3 ms
• Multichannel receiver
  • Direct access to up to 16 channels by means of direct generator/receiver access option
  • Parallel, synchronous sampling of channels, e.g. for phase measurements on antenna arrays
• Ideal for use in production
  • Parallel measurements on several DUTs increase throughput many times over
  • Reduced instrumentation effort
