5G and IoT Supplement
Rohde & Schwarz, a market leader in EMC test and measurement, presents a new CISPR 16-1-1 compliant EMI test receiver for the frequency range from 9 kHz to 7 GHz. The R&S ESCI7 already meets the requirements of the current edition of the CISPR 22/EN 55022 standard for information technology equipment, which will be valid from 2010. Starting in October 2010, radiated disturbance measurements up to 6 GHz will be mandatory for IT equipment in the European Union. The R&S ESCI7 enables test houses to adapt their services to these future requirements and helps manufacturers to avoid costly and time-consuming redevelopment effort. Like all EMI test receivers from Rohde & Schwarz, the R&S ESCI7 features an integrated spectrum analyzer.
The new EMI test receiver is a future-safe solution for all manufacturers who wish to sell products such as computers, modems or printers and the necessary components in the EU. They can detect and analyze radiated disturbance up to 7 GHz and check whether their products comply with the future limit values. Thanks to the integrated spectrum analyzer, the R&S ESCI7 can perform a large number of the standard measurements typically encountered in RF development labs. The receiver can measure phase noise, occupied bandwidth and adjacent channel power, for example, or determine the third-order intercept point.
The R&S ESCI7 is unique in its class because of its low displayed average noise level (typical –153 dBm at 1 GHz and 10 Hz bandwidth) and its wide dynamic range (1 dB compression point of +5 dBm). The test receiver offers the sensitivity required for high-precision EMC measurements using low limit values, as defined by the CISPR 22/EN 55022 standard for the frequency range from 1 to 6 GHz. This capability benefits users by reducing the necessary investment in external preamplifiers, low-loss cables or highly sensitive antennas.
The mixed-mode display of the R&S ESCI7 simultaneously shows the RF input signal in the spectrum around the receive frequency, the numeric measurement values and the level bargraph. This display mode gives users a better overview of the spectrum that surrounds disturbance signals and enables them to identify disturbance faster. It also allows more accurate tuning of the EMI test receiver to the local disturbance maximum.
