VSWR Measurement Kit

DSA800-VSWR option (used together with the VB1020 and DSA800-TG options)

provides measurement functions of S11-related specifications (such as the return

loss, reflection coefficient and VSWR).

Press Meas at the front panel and then press VSWR to enable the VSWR

measurement function. The screen is divided into two windows with the upper

window (the basic measurement window) displaying the sweep trace and the lower

window displaying the measurement wizard and measurement results. Perform two

measurements respectively according to the measurement wizard in the lower

window: measurement with the device under test disconnected (Meas Setup 

Cal Open, represented by trace 2) and measurement with the device under test

connected (Meas Setup VSWR, represented by trace 1). The return loss is

determined by the difference (represented by the math trace) of the results of the

two measurements and the reflection coefficient and VSWR are determined by the

return loss.
