The new R& S ZVT8 from Rohde & Schwarz is an eight-port vector
network analyzer up to 8 GHz for universal measurements on multiports and
balanced DUTs. Featuring true multiport architecture, the R&S ZVT8 offers
very short measurement times while maintaining high measurement accuracy and a
wide dynamic range. The instrument features high measurement and data transfer
speed and versatile remote control options for sophisticated tasks in the
development and production of multiport components.
The network analyzer is equipped with a measurement receiver and a reference
receiver at each of its eight test ports. It can thus perform measurements at
all ports of a multiport component simultaneously. This yields very short
measurement times plus a wide dynamic range and high measurement accuracy,
especially as compared with network analyzer systems based on switching
matrices. With its multigenerator concept featuring several internal generators,
the R&S ZVT8 not only performs fast measurements on multiports and balanced
DUTs but can also measure several DUTs simultaneously.
The R&S ZVT8 features a wide dynamic range of more than 120 dB, a maximum
output power of higher than 13 dBm at all test ports, and an electronic level
sweep range of 50 dB. Its modern Windows-based user interface includes wizards
for complex measurement tasks and is operated via an external monitor using a
mouse and keyboard. Up to 20,001 points per trace can be selected, and a
virtually unlimited number of diagrams, channels and traces is available.
The direct generator/receiver access option provides direct access to all 16
receiver and eight generator paths. Moreover, this option even further increases
the high output level and sensitivity of the base unit. The time domain option
enables, among other things, the elimination of discontinuities. The R&S
ZVT8 also offers state-of-the-art calibration techniques, allowing calibration
to be performed directly on wafer structures, for example.
For use in production, the R&S ZVT8 offers a number of special features
to speed up complex, remote-controlled test sequences. In addition to providing
remote control capability via its IEC/IEEE bus and LAN interfaces, it also
features a user control port for controlling test sequences and external devices
of production systems, thus eliminating the need for an external controller.
The R&S ZVT8 is now available from Rohde & Schwarz – from the
two-port base unit to the fully configured eight-port unit.
