Receiver Calibration
The E5070B/E5071B has a function to calibrate the gain of the individual receivers in
absolute value measurement.
The receiver calibration function calibrates the gain of the receiver by inputting the output
power of a stimulus port that has been assigned a correct value by the power calibration to
the port of the receiver you need to calibrate.
NOTE
Receiver calibration is valid only for the parameters of absolute value measurement.
Turning ON/OFF receiver error correction
The receiver calibration data are acquired for each channel/test port, so the error correction
of the power level can be turned ON/OFF independently for any channel or port.
The status of the power level error correction for each channel is indicated by one of the
symbols in the channel status bar in the lower part of the window, as shown in Table 4-10.

---
(displayed in gray) Error correction is not performed.
(At least one receiver port is turned on for error correction, but valid
calibration data are not available.)
None Error correction is not performed.
(Error correction is turned off for all of the receiver ports.)
Turning receiver error correction ON/OFF
The error correction of the receiver is automatically turned on when the calibration data are
measured. You can also turn this ON/OFF explicitly by following the steps below.
