General Dynamics 7200 User Manual

Operation
If Shell is set to DTR, the parameters in Table 5-1 will appear. If the Shell is set to
253_REC the parameters in Table 5-2 will appear. If Shell is set to TRL, the
parameters in Table 5-3 will appear. For all other Shell settings (Disabled, Printer,
M&C, Visual, etc.), the parameters in Table 5-4 will appear.
TABLE 5-1 DTR PARAMETERS
PARAMETER DESCRIPTION
Frequency [MHz] Frequency for the tracking receiver.
RF input Selects RF (polarization) input to the tracking receiver.
FFT Sample Averaging
FFT sample averaging controls this same function on the DTR. Increasing
this value will improve the stability of the signal. Decreasing the value
improves response time.
Filter Bandwidth This index value selects the DTR bandpass filter bandwidth.
DTR Detection Type
This selects the detection type used by the DTR. This is only available on
DTR receivers with "wideband" option; on standard DTRs, this will be
ignored. The default is "FFT signal", which is the only detection type
available on non-wideband DTRs. Consult the DTR Operations and
Maintenance Manual for further information.
TABLE 5-2 253 PARAMETERS
PARAMETER DESCRIPTION
Frequency [MHz] Frequency for the tracking receiver.
A/D channel The ACU A/D channel is connected to the analog signal output from the
receiver.
Bandwidth Selects narrow IF Bandwidth of the 253 Receiver
TABLE 5-3 TRL PARAMETERS
PARAMETER DESCRIPTION
Frequency [MHz] Frequency for the tracking receiver.
Attenuation [dB] Attenuation setting for the tracking receiver.
RF input Selects RF (polarization) input to the tracking receiver.
TABLE 5-4 ANALOG TRACKING PARAMETERS
PARAMETER DESCRIPTION
A/D channel The ACU A/D channel is connected to the analog signal.
Beacon One of four available beacon signals.
Tracking signal input is only used for signal-based tracking (i.e., Steptrack and
OPT). If the system is performing other types of tracking, the operator may want
to see what the tracking receiver "sees" for a particular beacon frequency.
For targets tracking in OPT, changes to these parameters remain in effect until the
target is restarted (or power is cycled). To permanently change a tracking signal
source, the system must be at Supervisor level and the changes must be made by
accessing the Edit a new or existing target... menu (refer to Section 5.8.2.6).
To edit any of the parameters under this menu, use the following procedures:
