Midspan Freq
Sets the center frequency of the current channel.
Remarks:
 When you modify the midspan frequency, the start and stop frequency will be
modified automatically if the span remains to be unchanged.
 Modifying the midspan frequency indicates that the frequency is changed along
the current channel horizontally, and the adjustable range should be within the
frequency range specified in the technical specifications of the analyzer.
 You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.
