The Rohde & Schwarz ESI7 EMI Test Receiver 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. It fully complies with the basic standard CISPR 16-1-1 and carries 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 ESI7 provides features for the test routines of the various stages of product development as well as for the final EMC certification tests. The main users of the Rohde & Schwarz ESIB7 EMI Test Receiver are: EMC test houses and service providers Governmental organizations Safety standard authorities Military Large industrial development and EMC labs (e.g. automotive) Features 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 ìs) Low inherent noise (<3 dBµV) Fast scanning in testreceiver 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) Time-domain measurements (zero span) at up to 50 ns resolution for interference source analysis.
