Key facts

  • Anechoic RF chamber with highly effective shielding > 110 dB 
  • Wide frequency range from 400 MHz to 18 GHz 
  • Automated 3D positioners for OTA measurements
  • Compact dimension suitable for any lab environment 
  • Unique design to maintain long-term high shielding effectiveness

OTA measurements on smallest footprint

The R&S®DST200 RF diagnostic chamber is the ideal environment 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, where it can be used at all times during the product design and optimization phase. The R&S®DST200 effectively assists in achieving high first-time pass rates during final type approval, which saves time and money.
The R&S®DST200 provides support for the radiated tests that are required in R&D, quality assurance, production and service. 

Features & benefits

Shorter product development process

Shorter product development process ensures faster time to market

The design of cutting-edge wireless devices such as multistandard smartphones requires extensive testing and verification. Radiated tests are essential during development and must be conducted using special test tools and environments. To minimize the total cost of ownership, test tools and environments should be flexible enough to be deployed at different sites.

High measurement accuracy and repeatability

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 layout of the pyramidal RF absorbers. This minimizes parasitic loading of the EUT as well as antenna detuning caused by conductive parts of the chamber frame.

Broadband test and communications antennas

All test antennas for the R&S®DST200 are designed as single modules and can be easily interchanged by the customer after opening the top cover of the R&S®DST200.
The communication antennas R&S®DST-B270 and R&S®DST-B270 can be mounted in horizontal or vertical orientation. This eliminates the effects of nulls in the 3D pattern and provides a stabel communication link.

Automated 3D positioner for OTA measurements

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

Individual calibration 

Individual calibration of the R&S®DST200 RFdiagnostic chamber

The optional reference antennas for path loss calibration ensure an accurate measurement procedure that can also be performed on-site. Two different
biconical broadband antennas are available: The R&S®TS-RANT3 with a frequency range from 400 MHz to 3 GHz covers the cellular and WLAN low frequency bands. The R&S®TS-RANT18 with a frequency range from 3 GHz to 18 GHz assures precise calibration for higher frequencies.

Automated measurements

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 test 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.
