The EMI Test Receiver R&S ESCI is a addition to the tried-and-tested family of top-class EMI test receivers from Rohde & Schwarz based on a spectrum analyzer platform.

The R&S ESCI measures electromagnetic emissions in full compliance with CISPR 16-1-1 and in line with all civil EMC standards and covers a frequency range from 9 kHz to 3 GHz.

Excellent RF characteristics

• Total measurement uncertainty < 1 dB
• Displayed average noise level (DANL) typ. –155 dBm
• 1 dB compression point +5 dBm
• Pulse-protected RF input
• Preselection filters
• Built-in 20 dB preamplifier

Outstanding performance

• Programmable scan table with up to 10 subranges
• Internal test routines for automated or interactive preview & final EMI measurements
• Evaluation functions for prescan, data reduction (peak list) and final measurement
• Spectrum analyzer
• Fast ACP measurements
• Time domain analysis (recording time > 2 h)

Versatile use

• Diverse IF filters (EMI, 3 dB, channel, RRC, FFT)
• Battery or AC supply operation
• Remote control operation
• PC-compatible screenshots
• Windows XP printer support
• USB interface
• Storable instrument settings
