——Choose from: dB μ V/m - (dB micro Volts per meter), dB μ A/m
- (dB micro Amps per meter), dBG (gauss), dBpT (tesla).
—— Freq Interpolation : Set to LINear and can NOT be edited.
— To edit Frequency/Value pairs, enter numbers using the numeric
keypad, and a frequency suffix when necessary.
——For both Cable and Antenna correction , Positive numbers
indicate loss (we need ADD something positive to compensate
for it), and Negative is indicative of some existing gain.
—— 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.
—When one Freq/Value pair is entered, that correction value is applied
to the entire displayed frequency span.
—When two or more Freq/Value pairs are entered, the data points
between the lowest and highest frequencies are corrected. Linear
interpolation is applied between frequencies when necessary.
— Optionally choose from the following:
— Previous / Next Page Quickly scrolls through pages of Freq/Value
data.
