When the Center frequency fine is viewed, the spectrum often has a fat and a water peak. You can center the spectrum’s midpoint on the desired location. Center frequency fine adjustments are made on a usable bandwidth frequency range of

1. From the Worklfow Manager control panel, Scan menu, click Manual Prescan.

   

2. From the Manual Prescan screen, in the Transceiver Hardware Settings area, click the MPS menu and select Center Frequency Fine.

   • The change in frequency spread allows you to see both the fat and water peaks.
   • A negative number moves the peak to the left. If the transmit frequency is too high, subtract frequency.
   • A positive number moves the peak to the right. If transmit frequency is too low, add frequency.
