The Agilent/Keysight 85640A is a MIL-rugged, portable tracking generator engineered to extend the measurement capabilities of the 8560 Series spectrum analyzers. Operating from 300 kHz to 2.9 GHz, it enables scalar and spectrum analysis of RF components and subsystems, delivering gain, frequency response, compression, flatness, and return loss measurements. The instrument also characterizes harmonic and inter-modulation distortion, along with spurious products.
