Configuration Of The Ar3000A Companion Radio - AOR SDU5500 Manual

Receive mode
When the AR5000 receive mode is set from the SDU5500, the following results:
SDU5500 setting
WFM
NFM
AM
LSB
USB
CW
AUTO
Note: The AR5000 does not have a specific legend for WFM, IF bandwidth beyond 30 kHz
becomes WFM.
IF output
The AR5000 IF output setting is automatically configured when the SDU5500 & AR5000 communicate
for the first time, thus overwriting any manual setting.
Step adjust
The step adjust facility does not operate with the AR5000 when step-up or step-down is activated from
the SDU5500.
Attenuator
The attenuator selects 0dB or -10dB, -20dB cannot be selected. The relationship between attenuator
and CENTRE FREQUENCY of the SDU5500 is as follows:
Centre frequency
Below 1000 MHz (1GHz)
1000 MHz and above
Passive band scope
Should you prefer to operate the AR5000 from it's own front panel, it is possible to configure the
SDU5500 for "Other' companion radio and use the display unit as a band scope only. The Centre
Frequency will then always be displayed as 10.7 MHz but an OFFSET will be displayed making the
measurement of interesting traces possible.

4-2 Configuration of the AR3000A companion radio

Operation is possible with the AR3000A receiver. However a small modification is required in order to
provide a suitable 10.7 MHz IF output from the AR3000A. The modification requires special skills and
proper tools, some suppliers offer the AR3000A with this modification already carried out. Please
contact your supplier for technical assistance, failing this contact your closest AOR distributor:
