6 GHz Compact RF Production Tester RF Communications Test Set Rohde & Schwarz CMW280

The pre-owned R&S CMW280 condenses vector-signal generation, analysis and power metering into a 417 mm-deep chassis that frees valuable rack space on high-volume lines.

Covering 70 MHz to 3.3 GHz—with a key-code path to 6 GHz—it calibrates and verifies LTE, 5 G NR FR1, WLAN and Bluetooth modules using a single calibrated RF path. A 40 / 70 MHz IF bandwidth enables one-sweep EVM, ACPR and spur checks, while its –130 dBm to +8 dBm level range and ±0.5 dB accuracy eliminate external attenuators and amplifiers. Fast list-mode switching, SCPI control over LAN or GPIB and 24-month calibration intervals slash test time and operating cost, giving production engineers Rohde & Schwarz precision at a fraction of new-instrument pricing and with zero lead-time.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
