frequency is specified since it can be applied to either a C or P band signal. The downconverting
antenna setting determines how a specified C band frequency is interpreted in a system where both C
and P bands are enabled.
If a C band frequency is specified and the downconverting antenna is
enabled
, it is assumed the signal
is a C to P downconverted signal. The receiver is tuned to the P band equivalent and the automatic
inversion is used. If the downconverting antenna is
disabled
, the receiver is tuned to the specified C
band frequency and spectral inversion is not an issue.
If a P band frequency is specified, it is assumed there is no downconverting antenna. The receiver is
tuned to the actual P band frequency and the automatic spectral inversion is disabled.

Clock/Data Output Controls
The Clock/Data Output Controls section contains parameters for clock and data output for Channel A and Channel
B, as shown in Figure 252.
Figure 252: Output Controls Window
The Channel A Output options, shown in Figure 253, select what signals appear on the Channel A clock/data
outputs: DQE, No DQE, or Test Data.
•
DQE
–
Selecting DQE enables encapsulation of data on Channel A; if DQE is enabled in the Main Menu,
the output is encapsulated, otherwise it will not
•
No DQE
–
Selecting No DQE bypasses data quality encapsulation
•
Test Data
–
Selecting Test Data causes the output of the Data Generator to display on Channel A clock and
data
