Pass/Fail Limit (Specification) Descriptions
25. TXA NAMPS Modulation Limiting (kHz)
25. TXA NAMPS Modulation Limiting (kHz)
This sets the pass/fail limits when the transmitter circuits are tested
for their ability to prevent the transmitter from producing deviation in
excess of the rated system deviation for narrow voice channels. Limits
must be entered in kHz.
Pass/fail limits are defined by any applicable standard, such as:
• EIA Standard: Modulation Deviation Limiting
Example
If your standard states that the instantaneous peak and steady-state
deviations of the transmitter should not exceed the rated system
peak-frequency deviation of
±5 kHz, you would enter 5 as the Upper
Limit.
