SAF Ka-Band Spectrum Compact 24 – 40GHz Portable Analyzer Review, Teardown & Experiments

In this episode Shahriar reviews another SAF Spectrum Contact. This model covers the Ka-Band (24GHz-40GHz), intended for 5G mm-Wave field measurements. The K-Band unit offers additional functionality such as 10MHz minimum span as well as RBW/VBW control down to 100kHz.

The teardown of the instrument reveals a similar architecture to the previously reviewed V-Band unit. Various system components are analyzed and explained. Some of the instrument’s GUI capabilities are also presented.

For experiments, a 900-element 38GHz planer array antenna is used at a distance of 2.5 meters. A slow-FM modulated RF signal centered at 38GHz is generated and measured which allows for the antenna gain characterization as well as exploration of the instrument’s capabilities.
