Keysight Technologies’s E8740A Automotive Radar Test solution.

Keysight improves its E8740A automotive radar test solution

  • Keysight Technologies announced enhanced E8740A Automotive Radar Signal Analysis and Generation solution.
  • This new solution enables radar-based driver assistance systems to detect and mitigate risks of collisions.

The development of driver assistance systems (ADAS) and autonomous vehicles presents designers with one of the major challenges in terms of safety and reliability. Autonomous vehicles use integrated radar systems. According to the Society of Automotive Engineers (SAE), an autonomous vehicle can carry up to 24 radar sensors. Interference between sensors can seriously affect the reliability of these radars. A small error or unexpected behaviour of the system can lead to a critical situation or an accident.

The new version of the Keysight E8740A automotive radar signal analysis and emulation solution is based on physical layer instruments to verify radar performance in the radiofrequency (RF) range and in the mmWave range. This test solution, with its intuitive user interface, also generates various conditions encountered in the real world to solve problems related to potential interference from automotive radars.

The new Keysight E8740A solution for analysis and generation of automotive radar signals allows:

  • Creation of an automotive radar interference test sequence and a physical layer test plan from Keysight’s PathWave software platform.
  • Flexible generation of wideband signals (mmWave): frequency modulated continuous wave, continuous wave, orthogonal frequency division multiplexing (OFDM), and coded modulation.
  • Predefined test configurations according to automotive radar standards.

The Keysight E8740A automotive radar signal analysis and generation solution analyzes and generates radar signals in frequency ranges up to 24 GHz, 77 GHz and 79 GHz. It has a scalable analysis band from 2.5 GHz to 5 GHz.

It operates the X-Series UXA signal analyzer, which covers the frequency range from 3 Hz to 110 GHz in continuous scanning. This makes it possible to test radar signals at 79 GHz to verify their compliance with ETSI specifications using a single instrument without requiring an external mixer or down-converter.

UXA has a maximum analysis bandwidth of 1 GHz which can be extended to 5 GHz by connecting an external oscilloscope to the IF input. This analyzer has a DANL signal-to-noise ratio from -150 dBm to 110 GHz.

The Keysight 89600 VSA software allows an analysis of modulation characteristics with a maximum analysis bandwidth of 4 GHz.

The M8195A Arbitrary Waveform Generator (AWG) can produce signals with modulation bandwidths up to at least 4 GHz in various modulation formats.
