Frequency Range

The X-axis frequency range determines the frequencies that are measured for each
sweep. The default Start frequency is 0 Hz. However, the Start frequency can be set
as low as -100 MHz. The internal LO of the FieldFox can be seen at 0 Hz, which will
mask signals that may be present.
NOTE Although the start frequency can be set as low as -100 MHz, amplitude accuracy is
specified above 2 MHz. Below 2 MHz, frequency accuracy is maintained, but
amplitude accuracy is degraded.
