Nordic Mobile Telephone (NMT) Encoder
Standard
This NMT system standard for equipment you are testing. When a standard is
chosen, the Test Set automatically alters several corresponding parameters.
Operating Considerations
Each standard affects the following conditions:
• The types of frames that can be sent.
• The range of valid channel numbers.
• The encoding of the frame data.
• The frequencies tuned to for the various channel settings when CHAN programming
commands are executed in an NMT program.
• The interpretation of received frames.
The following standards are available:
STD450: Transmit and receive frequencies are in the 453 to 467.5 MHz range.
STD900: Transmit and receive frequencies are in the 890 to 960 MHz range.
