Power Calibration
The E5070B/E5071B has a calibration feature for power level output that uses the a 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 ON or OFF power level error correction

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 4-8 in the channel status bar in the lower part of the window.

Procedure to turn ON/OFF power level error correction
Power level error correction is automatically turned on when you execute the measurement
of calibration data. You can turn it on or off as necessary by using the following procedure.
Step 1. Press
Step 2. Press
Step 3. Select a port (see "Selecting target port of error correction").
Step 4. Press

Status of power level error correction
(displayed in blue) Error correction is performed for all stimulus ports
(displayed in gray) Error correction is performed for some stimulus ports
(displayed in Error correction is performed for all stimulus ports; interpolated
calibration data
(displayed in Error correction is performed for some stimulus ports; interpolated
calibration data
(displayed in gray) Error correction is not performed
(some stimulus ports have error correction set to on, but there is no
valid calibration data)
Error correction is not performed
(error correction is off for all stimulus ports)
*1.If you turn on the error correction fuction when the stimulus setting is different from
that when the power calibration data were acquired, power level error correction is per-
formed with interpolated calibration data only when calibration data can be interpolated
(extrapolation is not performed for calibration data).
