Source Control

This feature may require an option on some FieldFox models.
With the FieldFox internal source enabled, these settings allow you to make
simple, absolute power measurements. The source and the power sensor can
be physically separated by a long distance when using a long USB cable.
Set the internal source frequency by setting the frequency of the power
measurement. Learn how in the previous section.
Power Meter measurements are limited by the combined frequency ranges of
the internal source when enabled and the frequency range of the power
sensor. For example, assume the frequency range of your sensor is 9 kHz to 18
GHz and the frequency range of the FieldFox is 2 MHz to 6 GHz.
— With the Source ON, measurements are limited to 2 MHz to 6 GHz.
— With the Source OFF, measurements are allowed from 9 kHz to 18 GHz.
