Meas Setup
Open the parameter setting menu of the function selected in the Meas menu. This
key is only available when a measurement function is enabled.

Measurerment Results: return loss, reflection coefficient and VSWR.
 Return Loss: the formula is
)lg(10)(
ri
PPdBRL =
. Wherein,
)(dBRL
is the
return loss,
i
P
is the incident power and
r
P
is the reflected power.
 Reflection Coefficient: the ratio of the reflected voltage to the incident
voltage.
 VSWR: the ratio of the maximum voltage to the minimum voltage of the
standing wave.
This measurement requires the VSWR, VSWR bridge options and TG (DSA815-TG/
DSA832-TG/DSA875-TG/DSA832E-TG). Two measurements have to be performed
