With its outstanding RF characteristics, high dynamic range and measurement accuracy.
The ESW is the best choice for fast and reliable certification measurements. It meets the most stringent requirements in line with CISPR, EN, MIL‑STD-461, DO‑160 and FCC. The ESW captures and weights disturbance spectra very fast with its FFT based time domain scan.
The real-time spectrum analysis with spectrogram function permits detailed analysis of even the shortest disturbance signals. MultiView mode delivers a simultaneous display of results from multiple operating modes for best instrument usability.
| Key Features |
| Frequency ranges from 1 Hz to 8 GHz, 1 Hz to 26.5 GHz and 1 Hz to 44 GHz |
| In line with CISPR16-1-1, ANSIC63.2, MIL‑STD‑461 and FCC |
| Extremely high dynamic range and ultra high accuracy for demanding certification measurements |
| Ultrafast measurements with FFT based time domain scan (TDS) |
| Three TDS optimization modes maximize measurement speed or pulse resolution, covering all testing needs |
| Preselection with selectable highpass filters and notch filters for the ISM bands |
| EMI test receiver and signal and spectrum analyzer in a single instrument |
| Real-time spectrum analysis (R&S®ESW‑K55 option) with 80 MHz bandwidth and spectrogram function |
| MultiView function for multiple operating modes on a single screen |
| Benefits |
|
| Compliance Testing | The ESW complies with the CISPR 16-1-1, ANSI C63-2, MIL-STD-461 and FCC standards and offers all required bandwidths and detectors.
With pre-configured limit lines and test automation, the instrument is the ideal choice for EMI tests to all relevant standards.
|
| Superior FR Performance | The ESW has a wide dynamic range and high sensitivity to meet the toughest EMI compliance testing requirements.
The low noise and built in pre-selection with 21 filters enables accurate and reliable measurements.
|
| Advanced User Interface | The ESW features a touchscreen for convenient and intuitive operation on the 12.1" display.
The receiver has two additional customizable knobs that the user can assign functions to such as resolution bandwidth, RF attenuation and measurement time.
|
| Fast Scanning Speeds | Speed is Crucial.
The ESW offers ultrafast FFT based time domain scanning orders of magnitude faster than the conventional mode.
Scans in CISPR bands are performed in milliseconds while conducted disturbances up to 30 MHz are measured in on segment in real time.
The additional fast TDS mode enables even higher measurement speeds for pretesting.
|
| Real Time Measurements | The ESW captures signal in real time without any time gaps and with a bandwidth of up to 80 MHz.
Even the shortest pulses are resolved and displayed intuitively in the persistence spectrum and spectrogram.
Those displays present detection of signals that are otherwise hidden.
Sporadic, pulsed or drifting signals are easy to identify with the real-time spectrum analysis option.
