o Description: Enter a description for the antenna or cable correction
table. This is NOT the filename used to save the file.
o Antenna Unit: Units in which the measurement will be displayed. Select
NONE (default setting) to select from standard SA Units on the Scale
menu. Learn how on page 80.
o Choose from: dB μV/m - (dB micro Volts per meter), dB μA/m - (dB
micro Amps per meter), dBG (gauss), dBpT (tesla).
o Freq Interpolation: Set to LINear and can NOT be edited.
To edit Frequency/Value pairs, enter numbers using the numeric keypad,
o
and a frequency suffix when necessary.
o For Cable Loss, positive values are interpreted as LOSS; negative values
are interpreted as GAIN which is used to describe an amplifier.
o For Antenna Factor, only positive values are valid. Antenna factor
describes the dB value needed to accurately display a far-field signal in
terms that are in the units listed below. When the antenna has low gain,
or low efficiency, the dB value to be added is larger. Learn more about
Antenna Factor at:

o
When one Freq/Value pair is entered, that correction value is applied to the
o
entire displayed frequency span.
When two or more Freq/Value pairs are entered, the data points between the
o
lowest and highest frequencies are corrected. Linear interpolation is applied
between frequencies when necessary.
