Agilent 8590L Portable Spectrum Analyzer, 9 kHz to 1.8GHz

The Keysight 8590L is a low cost, but full-featured, frequency accurate RF spectrum analyzer designed to meet your general purpose measurement needs. The easy-to-use interface provides access to more than 200 built-in functions. 

• Frequency counter: Eliminate the need for a separate frequency counter with the built-in frequency counter-with ±2.1 kHz accuracy at 1 GHz (±7.6 kHz from 0 to 50 °C)
• Multiple resolution bandwidth filters: Optimize the tradeoffs of speed, sensitivity and the separation of closely spaced signals with your choice of 10 resolution bandwidth filters beginning at 1 kHz
• 145 dB amplitude measurement range: Measure signals directly with -115 dBm to +30 dBm amplitude measurement range
• One-button measurement routines: Save time, setup, and training with one button measurement routines such as Adjacent Channel Power, signal bandwidth and Third Order Intercept (TOI)
• Phase noise of 105 dBc/Hz at 30 kHz offset: Uncover small signals close to carriers with an internal phase noise that will not get in your way
• Dual interfaces: Operate remotely and print directly with the optional dual interfaces that combine either an GP-IB or RS-232 port with a parallel (Centronics) port
• Built-in tracking generator: Measure the scalar characteristics of your components with the optional built-in tracking generator and the Keysight 85714A scalar measurements personality
