Choose a source power between -10
dBm and 0
dBm for reference receiver calibra-
tion, to ensure a high-quality calibration.
Values entered for "Calibration Power Settings" and "Ref Receiver Cal Power" are mir-
rored to the "Cal Power Settings" and vice versa. The detector times determine the
trace noise during measurement of the calibration standards and the receiver noise
measurement. Generally, a higher detector time results in a better measurement result.
However, a certain trade-off to the overall calibration and measurement time has to be
found.

Noise Det Meas Time
Defines the detector time of the RMS detector which is used for the noise measure-
ment during a noise figure calibration in channel <Ch>.
Remote command:

Gain Det Meas Time
Defines the detector time of the AVG detector which is used for the gain measurement
during a noise figure calibration in channel <Ch>.

Power Cal wizard
The "Power Cal" wizard displays a single screen, showing the current source and
receive ports. It allows you to perform "Ref. Receiver", "Meas. Receiver" and scalar
source power ("Source Flatness") calibrations, based on the current power calibration
settings (see
Chapter 5.11.3, "Pwr Cal Settings tab"
