NMT Decoder
Input Level
This field specifies the signal level that you input. 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.
The input level should be set high enough to prevent false triggering, but low
enough to allow triggering for fluctuating signal levels.
De-emphasis can greatly affect the input level required for proper decoding.
When decoding NMT data streams, you should turn de-emphasis off (controlled
by the
De-Emphasis field on the AF ANALYZER screen.)

Load Test
This double field is used to select and load NMT tests from a variety of mass
storage devices. After the appropriate Mass Storage device is selected using the
field on the right, the desired NMT test is selected using the field on the left.
Operating Considerations
Directly entering a command into the NMT Test Entry field automatically
removes from memory any NMT test previously loaded using the
Load Test
field.
