Features & benefits

Reliable and flexible echo generation

Install up to four different, customer defined fixed delay lines to simulate unrelated object echoes
Simulate echoes with minimum delay for short range radar (SRR) sensor tests
Simulate echoes for long range radar (LRR) sensor tests
Select additional Doppler offsets to simulate radial velocity for each artificial object individually or for all artificial objects together

With the R&S®AREG100A it has never been easier to monitor the quality of automotive radar sensors in mass production.

Test today’s and tomorrow’s radar sensors

Choose a 24 GHz ISM band frontend, an E-band frontend or both together for sequential operation
Profit from a future proof wideband E-band frontend with 4 GHz instantaneous bandwidth for short range radar (SRR) sensor test
All frontends in a single antenna configuration for superior MIMO testing performance or in a two antenna configuration with high RX/TX isolation for lowest ringaround.

R&S®AREG100A with single antenna frontend for reliable testing of MIMO radar sensors

Ready for RED

Measure the sensor’s equivalent radiated isotropic power (EIRP) in line with the applicable standards with a connected R&S NRP8S(N) power sensor
Verify robustness of radar sensors against in-band interferers with a connected analog or vector signal generator
Measure occupied bandwidth and unwanted emissions with a connected signal and spectrum analyzer

The R&S®AREG100A and the R&S®FSW8 are the perfect team for convenient measurement of radar signal parameters in the E band.
