How to change the Channel Number of the Measurement
With Unit = Chan the FieldFox will NOT allow you to specify channels outside
of the selected Radio Standard.
—Press Freq/Dist
— Then choose from the following:
—Center Channel
Places the center frequency of the specified channel
in the middle of the X-axis.
—Start Channel
Places the lowest frequency of the specified channel at
the beginning of the X-axis.
—Stop Channel
Places the highest frequency of the specified channel at
the end of the X-axis.
To overwrite a custom standard that is already uploaded to the FieldFox,
you must first delete the *.csv file from the FieldFox, then re-upload the file
that contains the standard. A predefined internal standard (such as GSM
450) can NOT be deleted from the FieldFox.
