Key Facts

Each R&S®ESIB combines the high sensitivity, large dynamic range and selectivity of a high-end EMI test receiver with the flexibility and speed of a top-class spectrum analyzer.

Brief Description

Excellent technical specifications have been a distinguishing mark of Rohde & Schwarz EMI test receivers right from the beginning.

Key Facts

  • Each R&S®ESIB combines the high sensitivity, large dynamic range and selectivity of a high-end EMI test receiver with the flexibility and speed of a top-class spectrum analyzer.

    The R&S®ESIB EMI test receivers fully comply with the basic standard CISPR 16-1-1 and carry out measurements in conformance with all civil and military EMI standards such as CISPR, EN, VDE, ANSI, FCC, BS, ETS, VCCI, MIL-STD, VG, DEF-STAN, etc.

  • Outstanding performance

    

    • Frequency range 20 Hz to 7 GHz, 26.5 GHz or 40 GHz, depending on model
    • Very high sensitivity (NF typ. 10 dB)
    • Excellent large-signal immunity (1 dB comp.: +10 dBm)
    • Low measurement uncertainty (< 1 dB up to 1 GHz)
    • High measurement speed and result processing (min. meas. time 100 μs)
    • Low inherent noise (<-3 dBµV)

    The upper frequency limit of the R&S®ESIB26 and R&S®ESIB40 can be extended up to 110 GHz by means of external mixers (options R&S®FSE-B21 and mixers R&S®FS-Zxx required).

  • Scope of application

    Each R&S®ESIB offers features and test routines for the various stages of product development as well as for the final EMC certification tests.

    The main users of the R&S®ESIB are

    • EMC test houses and service providers
    • Governmental organizations
    • Safety standard authorities
    • Military
    • Large industrial development and EMC labs (e.g. automotive)
