Operation
5.8.6.2 Tracking Receiver Setup Menu
The Tracking receiver setup... menu is used at system installation time to configure
the tracking receiver. This must be done before invoking Steptrack or OPT. Setting
the volts/dB slope under this menu is necessary for proper Steptrack and OPT
operation.
This menu contains the following parameters, sub-menu, and function.
• Receiver controller
• Set 0 dB point
• Set -3 dB point
• 0 dB setting
• A/D slope
5.8.6.2.1 Receiver Controller Parameter
The setting of the Receiver Controller Parameter selects how the tracking receiver
is controlled. This only affects the "serial" tracking receiver input (i.e., a receiver
with serial link); if an analog signal input is used, this parameter has no effect.
The default, and normal, setting for this parameter is ACU. This setting signals the
system to assume the receiver to be in remote control, and receiver commands
(frequency, attenuation, and RF input) are sent from the 7200 to the receiver. If
the receiver is in local control, a Tracking receiver in local control alarm is issued.
The 7200 will continue to track with the signal sent from the receiver even when
this alarm is in effect.
Receiver is selected to allow control of the tracking receiver from the receiver's
front panel, or to allow the receiver to be controlled by another computer (M&C).
Tracking receiver commands will not be sent from the 7200 to the receiver, even if
it is in remote control mode.
To set this parameter, use the following procedures.
1.From the Main menu, select Edit system configuration.... Then select Tracking
receiver setup... and Receiver controller.
2.Use the up and down arrow keys to toggle between the preprogrammed choices
of ACU and Receiver. When the desired choice is highlighted, press [ENTER].
5.8.6.2.2 Calibrating the Tracking Signal
The parameters listed in Table 5-8 are used to set the volts/dB slope of the A/D
channel.
