Pass/Fail Limit (Specification) Descriptions

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.
