Menu Reference 3
E4418B Power Meter User’s Guide 121
The softkey menu structured to this key affects the channel setup.
Press this key to access the “Frequency/Cal Fac” menu which allows you to
enter the frequency of the signal to be measured or the calibration factor.
Depending on the type of power sensor connected and whether or not a sensor
calibration table or frequency dependent offset table is selected, the text on
some softkeys may appear grayed out. This indicates that they are not relevant
in the power meter’s current mode of operation.
Table 3- 1 details the
relevant softkeys in various modes of operation.
