4. Remove the power meter and reconnect the cable from the splitter to the
Signal Input port.
5. If you are not certain that the power level at the Reference Input port is
within the range shown in the preceding graph, measure the level using
the setup shown in
6. Remove the power meter and reconnect the cable from the splitter to the
Signal Input port.
7. After you complete the measurement set up procedures and begin
running the measurement, the computer will prompt you to adjust for
quadrature. Adjust the phase difference at the phase detector to 90
degrees (quadrature) by either adjusting the test frequency or by
adjusting an optional variable phase shifter or line stretcher. Quadrature
is attained when the meter is set to center scale, zero.
