Download Product Datasheet

Product Overview

The R&S ESIB7 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 family of 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.

The Rohde & Schwarz ESIB7 offers outstanding performance:

• Frequency range 20 Hz to 7 GHz
• 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)

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)

Features of the R&S ESIB7 EMI Receiver include:

• Fast scanning in test receiver mode and sweeping in spectrum analyzer mode
• Compliant with CISPR 16-1-1
• Two RF inputs Input 2 with additional pulse protection (20 Hz to 1 GHz)
• Integrated 20 dB preamplifier (selectable) 1 kHz to 7 GHz as standard; >7 GHz as option R&S ESIB-B2
• Preselection in receiver mode (fixed) and analyzer mode (selectable)
• Resolution bandwidths meeting MIL standards and CISPR 16 specifications in analyzer mode, -3 dB RBWs and -6 dB RBWs selectable
• Parallel detectors Peak, average, quasi-peak, CISPR average and RMS (max. four simultaneously)
• Automatic overload detection & autoranging
• Editors for user-definable transducer factors/sets and limit lines incl. integrated transducer factor/limit line libraries
• Internal test routines for automated or interactive preview & final measurements
• Evaluation functions for prescan, data reduction (peak list) and final measurement
• Split screen display (mixed analyzer/receiver mode) for detailed signal analysis
• Convenient scan table editor Up to ten subranges with individual parameter setting
• Automatic scan and display of traces in parallel (receiver mode) Max. four traces with up to 80.000 samples each (250.000 samples with one trace)
