.
XMT FRAME - The falling edge of the trigger signal will occur
on the channel 1 preamble of the signal on the digital generator
output and the rising edge will occur on the channel 2
preamble. The trigger output will go through a complete cycle
every transmitted frame.
.
XMT CLOCK - The trigger signal will be a square wave with a
period of 1/2 UI synchronized to the signal on the digital
generator output.
There are two monitor outputs provided on the rear panel of the
ATS-1 Dual Domain. These monitors function in both digital and
analog analyzer modes. These connectors provide monitor outputs of
the signal at the INPUT and after processing for the READING.
The INPUT monitor normally outputs a near-constant-amplitude
duplicate of the signal on the input. In Analog Analyzer mode, the
output will be a buffered version of the signal at the input to the
Analog Analyzer. In Digital Analyzer mode, the output will generally
be an analog version (converted by a D/A) of the audio signal
embedded in the digital signal used by the Digital Analyzer.
The ANALYZER monitor normally outputs the signal after all filtering
and processing, immediately before being detected by the final
reading meter. In Analog Analyzer mode, the output will come from
the Analog Analyzer reading. In Digital Analyzer mode, the output will
come from the Digital Analyzer (after being converted to an analog
signal by a D/A).
These signals vary significantly depending on the measurement
function, especially in the Digital-specific modes. See the block
diagram of the measurement, at the beginning of each measurement
function section in the Operation chapter. Each block diagram shows
the points in the signal path from which the monitors are taken.
