5. SETTINGS

The default situation is the selection of the internal 10 MHz reference carrier. Select in the CONFIG

menu the item CONFIG REF CARR INPUT. Scroll with the UP and DOWN arrow until INTERNAL

appears. Confirm with

ENTER.

However, it is possible to select an external reference carrier input. In the CONFIG REF CARR IN-

PUT menu you can select with the

UP or DOWN arrow the mode: AUTO [STATE : INTERNAL]. STATE

indicates which of the reference carriers is used, the internal or external one.

Only if an reference carrier of 40 dBmV ± 6 dB with the correct frequency (adjustable by the user) is

connected to the connector REF IN at the rear panel, the STATE indication will change to EXTER-

NAL. Now the external reference carrier is used.

The frequency of the carrier is depending on the user’s selection. This selection is done in the follow-

ing menu CONFIG / EXT REF CARR INPUT. With the

UP and DOWN arrow the required selection

between 6, 7, 8 or 10 MHz can be made.

Pressing the

UP or DOWN arrow gives the following message:

‘THIS IS AN ALIGNMENT!!’

Press

ENTER and make the selection of the required frequency.
