Figure 5. Relative mode power measurement linearity with an EPM-P series power meter, at 25 °C (typical)
Figure 5 shows the typical uncertainty in making a relative power measurement, using
the same power meter channel and the same power sensor to obtain the reference and
the measured values. It also assumes that negligible change in frequency and mismatch
error occurs when transitioning from the power level used as the reference to the power
level measured.
