Using alternate DTF band
You can use the Alt DTF Band that is available only in DTF measurements after a calibration to scale
down of a specific sub-band without a need of an additional calibration.
Two independent sweeps can be performed, for example, one Reflection measurement and the other
DTF measurement.
Setting alternate DTF band
1 Tap the Menu ( ) key on the side bar and tap Alt DFT Band . If you have dual displays on the
screen, make sure to select a DTF measurement display for which you like to set. The alternate DTF
band setting window appears.
2 Select On for the Alt DTF Band to enable or Off to disable. Input the values of Start Frequency,
Stop Frequency, Center Frequency, Span Frequency using the on-screen keyboard.
