Detecting and eliminating electromagnetic interference

The EMI precompliance application (K54 option) for Rohde & Schwarz signal and spectrum analyzers is the ideal extension for EMI analysis during product development and to prepare for a smooth product certification process. Typical fields of application include commercial, automotive, avionic and military product developments (CISPR, EN, FCC, DO-160 and MIL-STD-461 standards).

Features & benefits

Conclusive results

Detectors in line with CISPR 16-1-1: peak, quasi-peak, CISPR-average, RMS-average
6 dB bandwidth in line with CISPR 16-1-1: 200 Hz, 9 KHz, 120 kHz and 1 MHz
6 dB bandwidth in line with MIL-STD-461 and DO-160: 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz and 1 MHz
Selection of one or more transducer factors to compensate for e.g. antenna factors or cable attenuation
Limit lines: More than 170 EMI limit lines based on the latest versions of common EMI standards

**Transducer definition (example from R&S®FPL1000)** - Selection of two transducer factors (line impedance stabilization network and related cabling).

Measurement automation

Repeatable and fast measurement thanks to automated test sequence

Pretesting: Sweeping of set frequency range with one or more fast detectors (e.g. peak or average)
Identification of critical frequencies: Automatic detection of peaks and limit deviations as well as tabular overview of frequencies found
Final measurement of identified frequencies: Automatic final measurement using detectors that require a longer measuring time (e.g. quasi-peak) and final evaluation based on the set limit line

**Measurement automation (example from R&S®FPL1000)** - Two detectors are used for the sweep. The identified maximum values are listed and automatically remeasured. PASS/FAIL status is clearly shown.

In-depth signal analysis

Up to 200 001 sweep points for high frequency resolution even with large span/small measurement bandwidths
Logarithmic frequency scale for in-depth analysis of low frequencies despite wide frequency range
Zero span measurement for analyzing the signal behavior over time of selected frequencies with standard detectors and CISPR detectors
AM and FM demodulation with audio output to identify ambient interferers

**Zero span measurement (example from R&S®FPL1000)** - The signal is analyzed over time at 580 kHz. The repetition rate of the interference is 50 Hz (20 ms).

Efficient and fast

Limit lines: More than 170 EMI limit lines based on the latest versions of common EMI standards (CISPR/EN, FCC, MIL-STD-461 and DO-160) for fast and accurate configuration of the measurement setup
LISN remote control: Simplified test execution by controlling connected Rohde & Schwarz LISNs.
Report generation: Output of measurement results at the push of a button

**Limit line selection (example from R&S®FPL1000)** - Limit line selection for electric tools up to 700 W and definition of visibility and trace assignment.

R&S®ELEKTRA EMC test software support

The R&S®ELEKTRA test software controls entire EMC systems and automates measurements of equipment under test (EUT). R&S®ELEKTRA simplifies configuration of test systems and test descriptions in line with common standards. It speeds up test execution and paves the way to quickly generating a comprehensive test report.

**Automated EMI measurement with R&S®ELEMI-E** - The R&S®ELEMI-E EMI test software, a simplified version of the R&S®ELEKTRA software, is ideal for EMI measurements during development.
