Frequency Type

Selects the frequency type as either ABSolute or OFFSet:

ABSolute

The frequency range is determined by Abs Start Freq and Abs Stop Freq. Absolute

and offset frequencies are not coupled

OFFSet

The frequency range is determined based on Offset Start Freq and Offset Stop

Freq. Abs Start Freq and Abs Stop Freq are coupled with the offset parameters

and show the actual frequency ranges. The following coupling equations are used

to calculate Abs Start Freq and Abs Stop Freq

When Offset Side is Negative:

[Abs Start Freq] = [OB Start Freq] – [Offset Stop Freq]

[Abs Stop Freq] = [OB Start Freq] – [Offset Start Freq]

When Offset Side is Positive:

[Abs Start Freq] = [OB Stop Freq] + [Offset Start Freq]

[Abs Stop Freq] = [OB Stop Freq] + [Offset Stop Freq]

When changing OB Start/Stop Freq, Abs Start/Stop Freq is changed and Offset

Start/Stop Freq remains unchanged.

When changing Offset Start/Stop Freq, Abs Start/Stop Freq is changed and OB

Start/Stop Freq remains unchanged.
