SA (Spectrum Analyzer) Mode 85
How to use the Antenna/Cable Editor
Press New then Yes to clear all data from the existing Antenna or Cable table
and reset header information to default settings.
Then Edit Antenna or Edit Cable to open the Antenna / Cable Editor.
Then use the ▲|▼ arrows to select a field,
o To edit header information, press Edit then modify the selected field using
the FieldFox labeler.
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.
o To edit Frequency/Value pairs, enter numbers using the numeric keypad,
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

o
o When one Freq/Value pair is entered, that correction value is applied to the
entire displayed frequency span.
o 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:
o Previous / Next Page Quickly scrolls through pages of Freq/Value data.
o Add Data Add a blank Freq/Value pair to the table,
o Delete/Clear then:
o Delete Line Remove the selected Freq/Value pair from the table.
o Clear All then Yes Remove all Freq/Value pairs from the table and resets
header information to default settings.
When the table edits are complete
Press Done to close the Antenna/Cable Editor.
