News - Updates from the World of SPINNER

The new bearing-free, and thus maintenance-free, rotary joint has a free internal diameter of 140 mm and enables on the one hand a safe IO-Link transmission of two IO-Link channels and on the other hand contactless energy transmission to provide the power supply for the connected sensors.

Have you ever been annoyed by a faulty test port connector on your network analyzer? To blame yourself would probably be the wrong answer here. That’s why we prefer to offer solutions: The new ruggedized precision test port adapters.

To ensure mobile wireless communication coverage in the 185-meter-high Omniturm, an office and residential building in Frankfurt am Main’s city center, the developers have decided to install a passive DAS system containing SPINNER products.

Calling all cell tower technicians! The new SPINNER 3-in-1 OSL compact calibration kits for the NEX10® and 4.3-10 coaxial connector systems will be available in July. This means that you can save measuring equipment weight when climbing a cell tower and still perform a complete OSL (Open, Short, Load) 1-channel calibration of the network analyzer.

The SPINNER Antenna Monitoring System (AMS) has evolved in recent years into a tool that goes beyond merely arc detection. A breakthrough was the addition of innovative VSWR monitoring, which is much more than a normal power reading at a directional coupler.

At the Mobile World Congress in Barcelona in February 2022, visitors witnessed the first end-to-end commercial 5G Broadcast solution in action. A live signal was transmitted within the exhibition center in Barcelona, using a Rohde & Schwarz transmitter, sectorized antenna systems from Cellnex and a smartphone form-factor test device from Qualcomm Technologies. SPINNER supplied a mask filter from its portfolio.

This new contactless GigE rotary transmission solution now makes it possible for SPINNER to supply products with an especially large inner diameter for dependably transmitting Ethernet protocols across a rotating interface. The joints feature a clear inner diameter of 300 mm and enable reliable Gigabit-Ethernet-LAN transmission. This isn’t possible with conventional sliprings or other technologies.

SPINNER has just released an important component for enabling the concurrent use of TDD and FDD in the 2600 MHz frequency band: our new diplexer BN 570761, which lets you combine bands 7 and 38 without any interference.

The scattering parameters of a device under test (DUT) are measured using a vector network analyzer (VNA). Before starting, however, the VNA should be calibrated applying a set of known calibration standards to identify and minimize systemic errors. Accurate calibration is a must for reliable results.
