Product overview
The R&S®ESW is the flagship EMI test receiver from Rohde & Schwarz, covering up to 44 GHz and equipped for both pre-compliance and full compliance electromagnetic interference measurement. The ESW receiver architecture is in line with CISPR 16-1-1, ANSI C63.2, MIL-STD-461, FCC, ETSI EN and DO-160, and one instrument serves as both spectrum analyzer and EMI receiver. A very low noise floor (ESW8 reaches < -7 dBµV), a resolution bandwidth as narrow as 1 Hz, and a strong dynamic range (1 dB compression point +15 dBm) let the ESW capture interference accurately from industrial equipment through to military platforms — the top choice for an EMC laboratory or a development engineer.
Key features
- Frequency range up to 44 GHz, covering every major EMC test band (the full CISPR A/B/C/D/E range)
- EMI receiver and spectrum analyzer in one box: pre-compliance and compliance measurements on a single instrument
- In line with CISPR 16-1-1, ANSI C63.2, MIL-STD-461, DO-160 and other civil and military standards
- Resolution bandwidth (RBW) down to 1 Hz and up to an optional 80 MHz (R&S®ESW-B8)
- A low-noise preamplifier (ESW-B24) raises sensitivity for weak interference measurements
- Multichannel CISPR APD measurement (K58) and 4-channel click rate analysis (K59), as CISPR 14-1 requires
- 80 MHz wideband real-time measurement (K55) sweeps bands faster and shortens test time
- An OCXO precision reference (B4) keeps frequency stable through long measurements
Typical applications
- EMC pre-compliance testing ahead of CE / FCC certification, to shorten time to market
- MIL-STD-461 conducted and radiated interference testing of military electronics
- DO-160 environmental conditions and electromagnetic compatibility testing of avionics
- EMI measurement on automotive electronics (CISPR 25) and industrial equipment (CISPR 11)
- EMI characterization and certification of 5G and millimeterwave equipment up to 44 GHz
- Full-band measurement services at third-party EMC laboratories, for civil and defense products alike
