The R&S®ESW8 from Rohde & Schwarz is an EMI Test Receiver that operates from 1 Hz to 8 GHz for compliance testing. It has built-in preselection and meets the most stringent requirements in line with CISPR, EN, MIL-STD-461, DO-160 and FCC. This receiver combines the functions of an EMI test receiver and a full-featured spectrum analyzer in a single device. It offers ultrafast measurement with the FFT-based time domain scan (TDS) besides the conventional stepped scan mode.

The R&S®ESW8 has three TDS optimization modes – dynamic, fast and automatic – to maximize measurement speed or pulse resolution, covering all testing needs. This receiver features highpass filters as well as notch filters for the ISM bands. These filters prevent high carrier signals in these bands, e.g., Bluetooth® and WLAN, from affecting the instrument’s dynamic range. It has a touchscreen GUI for convenient, intuitive operation. All functions and measurement parameters can be configured using either keys and knobs on the instrument, or a mouse and keyboard.

The R&S®ESW8 has a color display provides good readability and it can be remotely controlled via its standard IEC 625-2 (IEEE 488.2) interface or a LAN interface (10/100/1000BASE-T). It is available in an enclosure that measures 462 x 240 x 504 mm.
