Chapter 8, Signaling Decoder Screen
Using the NMT Decoder/Encoder
General Decoder Operation
The NMT Decoder screen has several uses:
• Entering NMT programming commands.
• Loading existing NMT tests from a variety of storage media.
• Running NMT tests.
• Decoding received NMT signals.
Operating Steps
Manual NMT radio tests generally follow four basic steps:
1. Write your test program to send encoded information and evaluate received frames.
2. Enter the necessary information into the various encoder and decoder fields.
3. Make the required Test Set AF Analyzer, RF Analyzer, and RF Generator settings.
4. Load and run your program from the decoder.
Changing Standards: Each NMT standard affects several operating parameters for the
encoder and decoder screens; however, there are no visual changes to the contents of
either screen when standards are changed. You must be aware of these changes when
manually testing radios using these screens.
Refer to the Standard and Calling Channel Number field descriptions for expla-
nations on the effects of these fields
