The IQS100B-22 module is an add-on to the IQS100B-11 to add an electro-mechanical impedance tuner to the setup and perform measurements under VSWR variation. This option is only supported for a Vector Bench setup. A basic two-dimensional (2D) sweep is by default available in IQSTAR, where the user can enter a list of frequencies and power levels. In release 1.3, the VSWR sweep is added with the module IQS100B-22, allowing three-dimensional (3D) nested loops sweep.
