Very-Near-Field EMI/EMC Scanning Device
EMC and signal integrity are critical considerations in the design of ultra-high-speed PCBs (>2 GHz). EMScanner+ empowers design engineers to identify and resolve EMC/EMI issues across a frequency range of 150 kHz to 6 GHz.
The system provides pre- and post-EMC compliance testing, delivering real-time emissions data without the need for an external spectrum analyzer. Its plug-and-play design allows engineers to quickly visualize the root causes of potential EMC and EMI problems, streamlining the debugging process.
During PCB development, engineers must locate, characterize, and mitigate unintended radiators or RF leakage to meet compliance requirements. EMScanner+ enables early-stage pre-testing, allowing designers to address EMC and EMI issues before formal compliance testing, thereby avoiding unexpected failures.
Key Benefits:
- Reduces testing time, which reduces financial outlay for testing
- Achieves documented 50% reductions in design cycle time
- Provides immediate comparison and analysis of design iterations
- Ideal for high-speed, high-power, or high-density PCBs
Capability
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines and report generation.
Spatial Scan Time
Continuous real-time or sub-second single scan for entire scan area Dependent on spectrum analyzer performance.
Spectral Scan Time
45 seconds for L 10 cm x W 10 cm (L 4” x W 4”) PCB with a 100 MHz span and 100 kHz RBW. Scanning time varies with size of scan area and node setting with the software.
