Features & Benefits
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
Brief Description
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.
