Description

The Keysight U3020AS16 is a 10 MHz to 26.5 GHz switching Test Set that allows

the user to make Reflection and Transmission measurements with 16 available test

ports when combined with a 2-port network analyzer. Transmission measurements

can also be made between any pair of the 16 test ports.

The Keysight U3020AS16 has the following key features:

The Keysight U3020AS16 will be referred to as the Test Set throughout this

document.

— Frequency Range of Operation: 10 MHz to 26.5 GHz.

— Sixteen Test Ports (3.5 mm female connectors).

— Low Loss Mechanical RF switching.

— Active Test Port LED indicators.

— Test Set control is processed via the LAN or GPIB rear panel interfaces.
