Rohde & Schwarz ESU8 EMI Test Receiver
Leading in performance
The ¸ESU is a high-end EMI test receiver for standard-compliant measurements in accordance with CISPR16-1-1 and meets all civil and military standards for EMI measurements.
The test receiver is available in three frequency ranges: from 20 Hz to 8 GHz, 26.5 GHz or 40 GHz.
The wide dynamic range combined with low inherent noise and low measurement uncertainty ensure high-quality test results. Comprehensive functions such as configurable RF scan, realtime IF analysis and fast Fourier transform (FFT) analysis for overview measurements provide accurate, quick and reliable solutions to any measurement problem. All detectors used today in EMI test and measurement (peak, AV, RMS, CISPR-AV and quasi-peak) as well as the CISPR-RMS detector, which will be important for evaluating interference in the future, are of digital design and ensure high stability and reproducibility of measurements.
The ¸ESU family is based on the tried-and-tested concept of combining a test receiver and a spectrum analyzer in one box, which provides a full-compliance test receiver and a full-fledged, top-class spectrum analyzer.
High measurement speed
Measuring the EMI of a product is very complex and requires not only significant technical effort but also considerable time. In particular recording and evaluating RFI field strength is one of the most time-consuming tasks in EMI test and measurement.
The time-domain scan, which the ¸ESU family offers as a commercial solution for the first time, is a new method for overview measurements and is based on FFT. The test receivers perform extremely fast measurements in the time domain in consecutive frequency intervals, which considerably reduces the amount of time needed for a measurement. A frequency scan from 30 MHz to 1 GHz with an IF bandwidth of 9 kHz is more than 50 times faster than the frequency-domain scan, plus it yields much higher throughput and reduces the costs per measurement. The time-domain scan is available as the ¸ESU-K53 option.
Simple, well-designed documentation
Easy-to-compile, conclusive and complete documentation of test results is highly important, especially in EMC test and measurement. The convenient report generator of the ¸ESU family and editable templates make it easy to compile test reports. After the report has been finished, you can check it using the preview function and then print it for your own documentation or save it as a file in PDF, HTML or RTF format on a data carrier (internal hard disk, optional flash card or USB stick). In addition, the screen content can be stored as a hard copy in BMF, WMF or EMF format and subsequently processed using a word processing program.
Detailed EMI tests made easy
Manual measurement is still the most effective means of identifying, locating and eliminating sources of electromagnetic interference. This is supported by the ¸ESU's large-sized, high-resolution and easy-to-read color display, which presents all the necessary information at a glance. Besides displaying numeric data for the different detectors, the EMI test receiver displays this data in parallel by means of an analog bargraph. You can thus immediately see the effect of manipulations on the device under test. In the lower part of the screen, the instrument shows either the complete RFI spectrum with limit lines or the spectrum about the set receive frequency (with realtime IF analysis). The IF analysis in particular helps you to evaluate EMI and gives you an impression of the condition near the set measurement frequency.
