The Agilent/Keysight 85711B is a signal source and test set engineered to expand network analyzer capabilities through integrated signal generation, routing, and switching functions. Operating across 1 GHz to 20 GHz, it delivers programmable output power with leveling to +13 dBm maximum, frequency resolution down to 1 kHz (1 Hz with Option 1E8), and phase noise performance spanning -107 dBc to -65 dBc SSB. The instrument supports automated testing and multi-port measurement expansion via SCPI command control, accommodating 50Ω nominal input impedance.
