Functions listed alphabetically
b = block mode, continuos mode to fiber at the fiber transfer rate of 250 Mbytes per
second.
c = continuous mode to local bus
d = continuous mode to fiber at the fiber transfer rate of 106 Mbytes per second.
spectralOrder
This parameter is intended for use only with the IF signal path, providing efficient and transparent
compensation for the effect of down conversion on output data. It does not generate an error if it is
set in baseband mode though
spectralOrder
remains AGE1439_NORMAL.
AGE1439_NORMAL
means that the spectrum of the output data will be in the same spectral
order as the input signal. That is, if the input signal increases in frequency from "right-to-left", so
does the spectrum of the output data.
AGE1439_REVERSED
means that the spectrum of the output data will be in the reverse spectral
order from the input spectrum. That is, if the input signal increases in frequency from "right-to-
left", the spectrum of the output data decreases in frequency from "right-to-left".
Changing the spectral order in multiple-module systems causes the LO to lose synchronization
with the other modules. Thus, in multi-module systems, the LO’s need to be re-synchronized after
this parameter is changed. See
age1439_filter_setup
for more information on synchronizing the
LO.
spectralOrderPtr
points to the current value of the
spectralOrder
for the current signal path. In baseband mode the
returned value is always AGE1439_NORMAL.
Return Value
AGE1439_SUCCESS
indicates that a function was successful.
Values other than
AGE1439_SUCCESS
indicate an error condition or other important status
condition. To determine the error message, pass the return value to
“age1439_error_message” on
page 102
.
