  • Page 7: Theory Of Operation

    THEORY OF OPERATION 2.1 General The user interface consists of an 8 digit display and 3 pushbuttons, frequency increase Ø, frequency decrease Œ, and options . On power up or key press, the synthesizer is interrogated ¸ ¸ ¸ ¸ for the current channel number and channel frequency.
  • Page 8 c) Both the Ø or Œ have two modes of operation. i. Single press is for small changes. Single button presses corresponds to single channel ( 25 kHz) steps. ii. Accelerated is for large steps. After 6 seconds of the button being pressed the frequency will change by8 channels per step (200 kHz).

  • Page 9: Alignment

    ALIGNMENT General Under normal circumstances no alignment is required to the Frequency Select Handle. Repair Note The Frequency Select Handle employs a high percentage of surface mount components, which should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should be performed only with specifically designed surface mount rework and repair stations complete with Electro Static Dissipative (ESD) protection.
