The R&S FPL1-K54 EMI measurement application adds EMI diagnostic functionality to the R&S FPL signal and spectrum analyzer. The R&S FPL1-K54 offers EMI bandwidths for commercial and military applications, detectors such as quasi-peak, CISPR-average, and RMS-average, limit lines, and correction factors.

EMI detectors in line with CISPR 16-1-1

• Flexible application of EMI detectors such as peak, quasi-peak, CISPR-average and RMS-average
• Fast, easy-to-read diagnostic measurements with high result reproducibility

Measurement bandwidths in line with CISPR and MIL-STD

Diagnostic measurements during development deliver the correct amplitude of the disturbance signal thanks to the 6 dB bandwidths (CISPR from 200 Hz to 1 MHz, MIL‑STD from 10 Hz to 1 MHz).

Measurement markers for evaluating EMI

• The ability to link markers to up to six traces and an associated EMI detector provides users with a direct reference to limits
• Automatic searching for disturbance maxima for reliable detection of time-varying interferers
• Critical frequencies are entered in a peak list for fast evaluation of a frequency spectrum with respect to official EMI emission limits

Marker demodulation

Fast and reliable identification of AM and FM signals.

EMI limit lines

• Selection of limit lines that meet international standards
• Easy generation, editing, and use of customer-specific limit lines
• Fast pass/fail test using activated limit lines

Frequency-dependent correction value tables

• Database with correction value tables for EMI accessories such as antennas, clamps, line impedance stabilization networks (LISN), pulse limiters, preamplifiers, cables, and attenuators
• Easy generation, editing, and storage of new correction tables
• Several correction tables can be combined to compensate for the entire test setup, e.g. including an antenna, a cable, and a preamplifier

Logarithmic spectrum display

The spectrum display with a logarithmic frequency axis makes it easy to analyze measurement results over a wide frequency range. Limit lines are displayed in accordance with the standards.
