The pre-owned R&S ESR3 unites a CISPR 16-1-1-compliant EMI
receiver with a high-dynamic-range spectrum analyzer, providing
full-standard emissions testing from 9 kHz to 3.6 GHz without
external mixers.
Integrated preselection, wide 10 Hz–10 MHz RBWs and selectable
peak, quasi-peak and average detectors let engineers verify
commercial limits and hunt spurious emitters in a single sweep. A
typical –168 dBm noise floor (with the 20 dB pre-amp) and ≤ 0.3 dB
total uncertainty secure confident margin analysis, while
USB/LAN—and optional GPIB—support automated limit-line scans and
remote logging.
Supplied fully tested, freshly calibrated and firmware-current,
this ESR3 offers immediate, cost-efficient pre-compliance
capability without sacrificing Rohde & Schwarz precision or
long-term serviceability.
