EMI Test Receivers ESBI and ESMI combine the top-class specifications of Rohde&Schwarz EMI test receivers with the speed of Rohde& Schwarz spectrum analyzers. The integral measurement and analysis functions simplify and speed up all measurements to the relevant commercial and military standards such as CISPR, VDE, FCC, EN, VCCI, MIL-STD, VG, DEF-STAN, BS, DO 160, GAM-EG13.
All these test receivers satisfy the exacting requirements of CISPR standard 16-1 (08.93) and VDE standard 0876. They are thus highly suitable for all compliance tests in line with commercial standards.
ESBI and ESMI provide excellent characteristics for EMI measurements. They can however also be used as top-class spectrum analyzers for general laboratory applications (further typical characteristics see data sheets PD 756.4808/.8384 and .7120).
