6.2.7.6 Calculated Satellite Delay
When the method for establishing the round-trip delay is set to Set location then the
satellite delay calculated by the modem will be displayed. This can be used to reduce the
acquisition time by setting minimum and maximum delay values based around the
calculated value. It can also be compared to the actual satellite delay reported on the
Status screen, with any significant difference in these two values potentially indicating a
false lock.
6.2.7.7 Minimum Round-trip Delay
Range: 0.01ms to 400ms ; step size: 0.01ms
Description: The minimum satellite round-trip delay.
To minimize the Paired Carrier™ acquisition time, set this to the actual
measured satellite delay value (shown on the Status->PCMA screen)
minus 0.5ms.
Table 6-78 Minimum Round-trip Delay
6.2.7.8 Maximum Round-trip Delay
Range: 0.01ms to 400ms ; step size: 0.01ms
Description: The maximum satellite round-trip delay.
To minimize the Paired Carrier™ acquisition time, set this to the actual
measured satellite delay value (shown on the Status->PCMA screen)
plus 0.5ms.

6.2.8 Edit->Memories Screen
The Edit->Memories screens shown in this section allow the user to store and recall
modem configurations (referred to as configuration memories). These can also be
uploaded and downloaded to and from a PC or equivalent to allow configurations to be
shared between different modems.
The following operations can be performed on configuration memories:
• Store. This allows the current M&C configuration to be stored to a named
configuration memory for later use. Up to 20 configuration memories can be created
(more may be stored if memory allows). The memories are non-volatile and will
persist between successive power-ups of the modem. Configuration memories can be
assigned any desired name using the alphanumeric keypad.
