Modern cars rely on complex electronic systems, and the Signal analyzer 9kHz~8.4GHz ensures their RF performance and EMC compliance. It solves interference and signal quality issues across key automotive subsystems.
ADAS Systems: Validating Radar & LiDAR Signals
Firstly, ADAS radar (24GHz/77GHz) and LiDAR modules need precise signal testing. The Signal analyzer 9kHz~8.4GHz captures their RF outputs, verifying parameters like bandwidth and signal-to-noise ratio (SNR).
Moreover, its wide frequency range covers both short-range and long-range ADAS sensors. This solution detects signal distortions that cause false collision alerts, enhancing driving safety.
In-Vehicle Infotainment (IVI): Ensuring Connectivity
IVI systems with Bluetooth, Wi-Fi, and 5G depend on stable RF signals. The Signal analyzer 9kHz~8.4GHz measures signal strength and interference, ensuring seamless phone pairing and media streaming.
Additionally, it identifies co-channel interference from nearby devices (e.g., smartphones). Engineers use this data to optimize IVI antenna placement, solving connectivity dropouts in dense urban areas.
EV Powertrain: Detecting EMI from High-Voltage Components
Secondly, EV high-voltage batteries and inverters generate EMI that disrupts electronics. The Signal analyzer 9kHz~8.4GHz scans for EMI in the 9kHz~8.4GHz range, locating interference sources.
Furthermore, its real-time spectrum analysis (RTSA) feature captures transient EMI spikes. This solution helps design shielding for powertrain components, preventing malfunctions in EV control systems.
Vehicle-to-Everything (V2X): Testing Communication Reliability
V2X systems (DSRC/C-V2X) require robust signal transmission for traffic coordination. The Signal analyzer 9kHz~8.4GHz tests V2X signal integrity, measuring packet error rates (PER) and latency.
For example, it simulates harsh RF environments (e.g., highway tunnels) to validate V2X performance. This ensures cars communicate reliably with infrastructure and other vehicles, supporting autonomous driving.
EMC Compliance: Meeting Global Automotive Standards
Finally, automakers must meet EMC standards (CISPR 25) to sell vehicles globally. The Signal analyzer 9kHz~8.4GHz conducts pre-compliance testing, detecting EMI that violates these regulations.
Its high dynamic range (≥150dB) captures weak EMI signals amid noise. This solution avoids costly rework by identifying compliance issues early in the design phase.
Core Value: One Tool for Multifaceted Testing
The Signal analyzer 9kHz~8.4GHz replaces multiple specialized tools, reducing test lab costs. Its intuitive software lets technicians automate tests, cutting setup time by 30% for high-volume production.
In automotive electronics, it’s not just an analyzer—it’s a solution that accelerates development, ensures compliance, and makes modern connected cars safer and more reliable.
