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)

Excellent technical specifications have been a distinguishing mark of Rohde & Schwarz EMI test receivers right from the beginning.
Each R&S ESIB model continues this tradition with the following characteristics:
