Key facts

Rohde & Schwarz provides a wide range of accessories for vector network analyzers.

Available accessories:

Calibration kits and calibration units

Rohde & Schwarz calibration devices support one-, two- and n-port calibration (such as OSM, TOSM, TRM, TOM, UOSM).

Calibration Kits:

  • available as a compact coaxial version, a high end coaxial set and as waveguide sets
  • available for all frequency ranges covered by Rohde & Schwarz VNAs

Calibration Units:

  • available as 2, 4, 6 or 8 ports
  • automatic detection, installation and control via USB interface
  • Full multiport calibration; Calibration Unit has to be connected only once
  • extremely short warm-up time
  • calibration of all analyzer test ports or test port subgroups
  • reliable electronic switching
  • recharacterization of Calibration Unit by the user is possible (e.g. to enable any combination of connector types on the analyzer and the calibration unit by using adapters and treating them as part of the calibration unit; requires a manual calibration kit for each connector type used on the calibration unit)
  • Precision Torque Wrenches are separately available

Test cables

Coaxial test cables are available to up to 110 GHz.

The R&S®ZV-Z9x high-performance test port cables are especially suited for precision measurements where high phase stability and high mechanical flexibility are required.

  • Designed for extremely accurate measurements in R&D and in the lab
  • Extremely stable and robust

Crush-resistant, 140 kg/cm (800 lbs/inch)

Highest phase stability with flexure

  • Extremely flexible

Almost no resistance to bending

No springback

Smallest bend radius 57 mm (2.25")

  • Ruggedized connector for analyzer test port
  • Ruggedized connector for DUT port (connector fits any standard connector on DUT side)

The semi rigid R&S®ZV-Z19x economy test port cables are mostly used for general-purpose applications.

  • Designed for general purpose and production test applications
  • Very stable and rugged

Internally ruggedized, crush-resistant, 40 kg/cm (250 lbs/inch)

Excellent stability with flexure

  • Highly flexible

Offers little resistance to bending

Smallest bend radius 26 mm (1")
