The softkey menu structured to this hardkey affects the channel setup.
Press this hardkey 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.

Press this softkey to enter the frequency of the signal to be
measured on channel A, in the range of 0.001 MHz to
999.999 GHz. The default value is 50 MHz. Use the , ,
and hardkeys to change the frequency. To confirm your
choice press the appropriate frequency unit. Entering a frequency
using this softkey is only possible when you have a sensor
calibration table or frequency dependent offset table selected or
you are using an Agilent E-series power sensor.
