Edit GPS Controller Configuration


To edit the controller configuration:

  1. Select the status in the Loop Status drop-down box. This indicates the status of the control loop. The selection includes:

INI - Loop is in the initialization stage. If in this stage, no other information is presented

ACQ - Loop is in acquisition

LOCK - Loop is in the Locked state

HALT - Loop updates are halted due to no, or invalid phase measurements

UHLT - Loop has been halted by user

  1. Select ON or OFF in the Auto Return drop-down box.

  2. Select ON or OFF in the Auto Switch drop-down box.

  3. Select 5 MHz or 10 MHz in the Frequency A drop-down box (Local Oscillator input A frequency).

  4. Select 5 MHz or 10 MHz in the Frequency B drop-down box (Local Oscillator input B frequency).

  5. Select RB or XTAL in the Type A drop-down box (Local Oscillator input A type).

  6. Select RB or XTAL in the Type B drop-down box (Local Oscillator input B type).

Note: If the local oscillator has the stability of a rubidium (or better), select RB. If the stability of the local oscillator is less than rubidium quality, select XTAL.

  1. Select A or B in the Primary drop-down box (Local Oscillator to use as the primary input).

  2. Select A or B in the Selected drop-down box (Local Oscillator input to select for input).

Note: If you attempt to select a Local Oscillator (LO) input that is faulted, no switch will take place. If auto return is on and you attempt to select an LO input that is not the primary LO input, no switch will take place.

  1. Click OK to accept changes and return to the GPS Reference Controller Module window, or Cancel to return to the GPS Reference Controller Module window without saving changes.
