10 MHz -40 GHz High Purity Low Cost Rf Signal Generator Agilent 83640B

The pre-owned Agilent 83640B delivers fully-synthesized accuracy together with analog-sweep convenience, spanning 10 MHz to 40 GHz in a single 3-U chassis. One-kilohertz tuning steps—or 1 Hz with Option 008—allow precise LO substitution and scalar network-analysis sweeps, while –80 dBc/Hz phase-noise performance keeps mixer and phase-noise measurements honest. With the optional step attenuator, a calibrated +10 dBm to –110 dBm power range covers PA compression, receiver sensitivity and EMC immunity tasks, and harmonics sit at least 50 dB below the carrier below 26.5 GHz to minimise unwanted products.

Fast band-to-band switching, SCPI/LAN automation and ISO-17025 calibration let the generator drop straight into production lines or R&D benches—delivering Keysight-grade signal purity and long-term serviceability at a fraction of new-instrument cost.

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.
