The Keysight (Agilent) 8595E is a portable spectrum analyzer delivering signal analysis from 9 kHz to 6.5 GHz with field-deployable convenience and benchtop performance. Engineered for RF, microwave, and digital signal characterization, it combines a calibrated amplitude range of +30 dBm to −130 dBm (with Option 130) with low displayed average noise levels down to −127 dBm, enabling detection of weak signals across the full frequency span. Frequency accuracy reaches ±210 Hz at 1 GHz with Option 004 (Precision Frequency Reference), while resolution bandwidth ranges from 1 kHz to 3 MHz with optional narrow RBWs as low as 30 Hz. The instrument supports zero-span operation and spans from 10 kHz to 6.5 GHz with ±2% to ±3% span accuracy depending on span size.
