In HPR 3, Elliot reviews the Keysight N6700C power supply, which only requires 1U of rack space yet has four slots in the back for a variety of modules. This configuration allows for a lot of functionality including output disconnect, reverse polarity, fine control over output timing, and individual relay control of each module. He also discusses the unique air flow requirements of this module and how to easily overcome this.

Paul Hiller, Hiller Measurements owner and co-founder, reviews the Keysight 8700 and 8900 series power supplies in HPR 2. These power supplies are frequently used by Hiller Measurements because they can generate high power in a small space with a design that does not require additional cooling, making it possible to put up to 150 KW of power in a 30U rack, but 208 V or 400 V three-phase power is required.  

In HPR 1, Hiller Measurements senior engineer Gerry Hiller offers a comprehensive review of the Keysight M980xA Network Analyzers. These instruments offer a small PXI form factor and can be used to create up to a 50-channel network analyzer in a single chassis. The M980x series can further save space with multi-mode functionality that reduces switching and also lower costs by allowing easy reuse of existing Keysight software.
