lets the user choose between automatically or manually setting the parameters used for the measurement functions under the Power Menu softkey. Parameters such as span, resolution bandwidth, video bandwidth, center frequency step size, detector mode, and sweep time are coupled so that they are automatically updated. With AUTO underlined when channel bandwidth or channel spacing are changed, the coupled parameters will be updated and another sweep will be taken and measured. If MAN is underlined the user must set all of the parameters correctly.
sets the minimum amplitude variation of signals that the marker can identify as a peak. If a value of 10 dB is selected, the marker moves only to peaks that rise and fall more than 10 dB above the threshold line (or the noise floor of the display). Pressing
