Agilent/Keysight 8560E

The Agilent/Keysight 8560E is a portable RF spectrum analyzer delivering precision signal analysis across 30 Hz to 2.9 GHz. Synthesized tuning eliminates drift while maintaining measurement accuracy across demanding RF applications. Built to MIL-T-28800 rugged standards for field deployment, the instrument combines exceptional sensitivity (–144 dBm at 1 GHz with 1 Hz RBW), wide dynamic range (100 dB third-order), and precise frequency accuracy (±135 Hz at 1 GHz after 15-minute warmup). Resolution bandwidths span 1 Hz to 1 MHz with ±10% accuracy from 1 Hz to 300 kHz. Video bandwidth ranges 1 Hz to 3 MHz. Phase noise measures –113 dBc/Hz at 10 kHz offset. The 100 dB on-screen calibrated amplitude display includes AMPCOR correction for cable loss and preamplifier gain compensation. RF input accepts +30 dBm average continuous power (≥10 dB attenuation) and +50 dBm peak pulse power (≥30 dB attenuation). Frequency reference aging rate is 1×10⁻⁷ per year with 1 Hz counter resolution.
