The pre-owned Agilent E4448A PSA delivers high-performance spectrum analysis from 3 Hz to 50 GHz, providing up to 80 MHz instantaneous bandwidth for wide-channel modulation tests and real-time troubleshooting.
With -118 dBc/Hz phase-noise and a -154 dBm noise floor, it cleanly resolves low-level spurs and meets stringent ACPR/EVM requirements. ±0.19 dB amplitude accuracy guarantees repeatable results across production and R&D benches.
Supplied fully tested, freshly calibrated and loaded with current firmware, this second-hand unit ships immediately and offers substantial cost savings over new PSA models, while retaining upgrade flexibility via Option 122 for wideband vector signal analysis.
