The power meter always carries out “Maths” calculations in Watts. The power meter displays the ratio of the channels power values in either dB or %. When the measurement result is displayed in % a prefix multiplier may be shown. The power value of each channel includes offsets, calibration factors and duty cycle in addition to measured power. The filter, range, offset and calibration factor are set individually for each channel.
Ratio measurements can be displayed relative to a stored reference. In relative mode readings are displayed in either dB or %. Refer to “Making Relative Measurements”, on page
