If reference impedance 2, 4, 8, or 16
Ω
is selected, the dBm modifier is
displayed in Watts (power).
! Operation procedures:
Condition 1:
then , the reference impedance currently used will be displayed
on the secondary display.
or to scroll to the desired value of reference impedance.
to store the selected value.
! Operation Example: Set the reference impedance to 1000Ω for dBm calculation.
