Agilent-Keysight 8564E en Lake Mary, Florida, USA

The 8564E portable millimeter spectrum analyzer offers the measurement capability and performance previously found in larger, more expensive benchtop analyzers. You can measure signals from 30 Hz to 40 GHz (preselected above 2.75 GHz) with a single coaxial connection.
The 8564E combines outstanding phase noise, sensitivity, 1 Hz resolution bandwidths, synthesized tuning and wide dynamic range in a MIL-rugged package built to withstand harsh environmental conditions. It offers a complete solution for adjacent-channel power (ACP) testing of burst carrier signals using digital modulation, and the ability to measure occupied bandwidth percentage.
9 kHz to 40 GHz
Continuous 30 Hz to 40 GHz sweep
Fast digital resolution bandwidths of 1, 3, 10, 30 and 100 Hz
