The pre-owned Agilent N5239B PNA-L offers reliable vector-network analysis from 300 kHz to 8.5 GHz with a generous 133 dB dynamic range and just 0.006 dB trace noise, giving clear visibility into small S-parameter changes without external boosters. A typical 24 ms cycle time for a 201-point full-span sweep speeds production throughput, while 3.5 mm test ports keep fixturing simple. Refurbished units ship ISO-17025-calibrated and firmware-verified, cutting capital costs and lead-time yet preserving Agilent accuracy, SCPI/LAN automation, and future upgrade paths.
