Rohde & Schwarz ESW8 EMI Test Receiver
The Rohde & Schwarz ESW8 is a cutting-edge EMI Test Receiver, renowned for its exceptional RF characteristics, including a high dynamic range and precision measurement accuracy. Designed to comply with the most rigorous certification standards—CISPR, EN, MIL-STD-461, DO-160, and FCC—this state-of-the-art instrument is tailored for the automotive and aerospace defense sectors.
Equipped with an FFT-based time domain scan, the ESW8 processes disturbance spectra in record time, transforming lengthy measurement intervals into mere seconds. Its advanced realtime spectrum analysis features a comprehensive spectrogram function, empowering users to deeply analyze disturbance signals along with their temporal history.
The Rohde & Schwarz ESW8 EMI Receiver distinguishes itself by offering:
- Impressive frequency range from 2 Hz to 8 GHz.
- Adherence to critical standards, including CISPR16-1-1, ANSIC63.2, MIL-STD-461, and FCC.
- The highest dynamic range and precision for sophisticated certification measurements.
- Ultra-fast measurement capabilities through the FFT-based time domain scan, significantly reducing measurement time.
- Integrated preselection options with selectable highpass and notch filters to effectively manage ISM band signals at 2.4 GHz and 5.8 GHz.
- Combining functions of an EMI test receiver and a full-featured spectrum analyzer within a single device.
- Advanced realtime spectrum analysis (available via K55 option) with a bandwidth of 80 MHz, allowing for the detection of hidden disturbances.
- A unique MultiView function that facilitates straightforward display of multiple measurements and traces, even in varying operating modes.
Enhancing its functionality, the Rohde & Schwarz ESW8 features:
- An exceptionally wide dynamic range, complemented by a low DANL (typical -168 dBm for f ≤ 1 GHz).
- A high 1 dB compression point of +15 dBm for the RF frontend.
- A superb high third-order intercept (TOI) (typical +25 dBm), ensuring advanced signal integrity.
- Superior measurement accuracy with a deviation of ±0.37 dB for frequencies up to 8 GHz.
- Integrated preselection filters comprising 21 filters standard to enhance signal analysis.
- An additional highpass filter at 2 MHz to suppress unwanted data carriers and disturbance signals.
- Dedicated notch filters engineered to mitigate strong carrier signals within the license-free ISM bands.
