Key facts
The R&S®DST200 RF diagnostic chamber is ideal for RF analysis during development. It supports a wide range of radiated test applications for wireless devices and fits on any R&D lab bench, for use at any time during the product design and optimization phases. The R&S®DST200 effectively allows for high first-time pass rates during final type approval, saving time and money.
The R&S®DST200 supports the radiated tests required in R&D, quality assurance, production and service.
Shorter product development process for quicker time to market
Designing cutting-edge wireless devices such as multistandard smartphones requires extensive testing and verification. Radiated tests are essential during development and require special test tools and environments. To minimize total cost of ownership, testing tools and environments should be flexible enough for deployment at different sites.
Test tools from R&D to type approval
The R&S®DST200 is a compact, RF shielded anechoic chamber with an integrated broadband cross-polarized
or circular-polarized test antenna for the frequency range from 400 MHz to 18 GHz.
Free-space conditions are achieved at the EUT test position through the optimized design and the layout of pyramidal RF absorbers. This minimizes parasitic loading of the EUT and antenna detuning from the conductive parts of the chamber frame.

R&S®DST-B150 manual 3D positioner is designed with RF transparent materials (Rohacell)
All test antennas for the R&S®DST200 are single modules that the customer can easily change out by opening the top cover of the R&S®DST200.;
The R&S®DST-B270 and R&S®DST-B270 communications antennas can be mounted with horizontal or vertical orientation. This eliminates the effects of nulls in 3D patterns and provides a stable communications link.

The optional R&S®DST-B160 3D positioner provides automated OTA measurements for TRP and TIS. The EUT is attached to a removable holder at the center of the positioner and rotated independently
on the azimuth and elevation axes by two servomotors. An optical sensor ensures high positioning accuracy.
The supporting structure is made from material with very low relative permittivity to minimize field perturbation in the EUT quiet zone.

Individual calibration of the R&S®DST200 RF diagnostic chamber
The optional reference antennas for path loss calibration ensure accurate measurements that can be performed on-site. Two different
biconical broadband antennas are available. The R&S®TS-RANT3 has a frequency range from 400 MHz to 3 GHz for cellular and WLAN low frequency bands. The R&S®TS-RANT18 has a frequency range from 3 GHz to 18 GHz for precise calibration of higher frequencies.

Automated measurements with ready-to-use test templates
The comprehensive R&S®AMS32 OTA performance measurement software supports various test applications with the R&S®DST200 RF diagnostic chamber:
- Verification of over-the-air (OTA) performance (TRP, TIS)
- Coexistence testing to verify receiver performance with multiple radio services active simultaneously in a wireless
device (e.g. LTE and Bluetooth®)
Easy test configuration for
parameters such as cellular band and power level.
