Overview
The E5071C has a calibration feature for power level output that uses the
power meter (power calibration).
The power calibration function outputs a stimulus signal with a more
accurate power level (closer to the set value) by measuring calibration
data (power level) in advance with the power meter and sensor. Then this
function performs error correction of the power level by using the
calibration data.
Turning Power Level Error Correction ON/OFF
Power calibration data are acquired for each channel/test port, and you can
turn ON/OFF the power level error correction independently for any
channel or test port.
The status of the power level error correction of each channel is indicated
by one of the symbols shown in table below in the channel status bar in
the lower part of the window.

Error correction is performed for all stimulus ports;
interpolated calibration data is used. If you turn on
the error correction function when the stimulus
setting is different from that when the power
calibration data were acquired, power level error
correction is performed with interpolated calibration
data only when calibration data can be interpolated
(extrapolation is not performed for calibration data).
