Chapter 8, Signaling Decoder Screen
LTR Decoder
Data Rate
This display field lists the data rate of the received signal.
Operating Considerations
This measurement relies on the LTR Encoder screen’s data rate setting. Set the
encoder’s
Data Rate field to the expected incoming data rate for accurate
measurements (typically 297.6 bps).
Gate Time
This field specifies how long the decoder analyzes a signal after it has been
triggered.
Input Level
Enter the expected data signal level in this field (typically 1 kHz for LTR data).
The higher the level of signal expected by the analyzer, the higher the Trigger
Level is set.
Operating Considerations
The unit-of-measure is determined by the AF Anl In setting (kHz when the input
is
FM Demod).
The input level should be set high enough to prevent false triggering, but low
enough to allow triggering for valid signals.
