Configuration Of The Receiver - AOR SDU5600 Operating Manual

5-2-1 Configuration of the Receiver

This section explains how to configure the
companion receiver itself. Note that this section
will not apply when Other(10M) or Other(45M)
has been selected in the receiver selection
menu, or communication has not been correctly
established between the SDU5600 and companion
receiver.
On the right of the main keypad there are three
control keys which directly affect the operation of
the companion receiver, these are MODE (receive
mode), STEP (tuning step) and ATT (attenuator).
Their operation in companion with the SDU5600
is described below.
Receive (Demodulation) mode - MODE
This key is used to select the receive mode of the companion receiver (NFM, AM etc). Press the
MODE key to activate the RX.MODE menu, the corresponding LCD legend flashes in reverse
contrast. Rotate the main dial to scroll the various receive modes. Press the ENT key to accept the
displayed the receive mode.
Frequency step - STEP
This key is used to select the tuning step size of the
companion receiver . Press the STEP key to
activate the RX.STEP menu, the corresponding
LCD legend flashes in reverse contrast. Tap in the
step size via the ten-keys then press the ENT key.
Any step size which is not supported by the
companion receiver will be rejected by the
SDU5600 and the LCD will revert to the previous
step size.
Attenuator - ATT
This key is used to activate or deactivate the attenuator of the companion receiver as a toggle, each
push of the ATT key will alternate On/Off and the corresponding LCD legend RX.ATT will confirm the
status.
AUTO mode of the companion receiver
When the companion receiver is equipped with an auto mode feature where the IF filter bandwidth
and receive mode can be changed independently (such as the AR5000A), the SDU5600 cannot
make changes to the IF bandwidth. For this reason, it is suggested that auto mode be used or the
bandwidth selected manually if only one receive mode is to be used while operating with the SDU5600
in the current session.
Revert to the parameters which have been previously configured
ê Press FUNC + S.MODE/MODE to revert to the previously selected receive mode.
ê Press FUNC + S.STEP/STEP to revert to the previously selected receive tuning step size.
ê Note, these facilities do not operate once the SDU5600 has been switched off and on.
Value of the attenuation (amount of attenuation)
The amount of attenuation is determined by the attenuator of the companion receiver. With the AR5000
series receiver the attenuation can be manually selected from the receiver' front panel. However when the
attenuator is switched on from the SDU5600's front panel it will select only the AUTO position of the
receiver.
