Pass/Fail Limit (Specification) Descriptions
20. TXA Frequency Error (ppm)
20. TXA Frequency Error (ppm)
This sets the pass/fail limits for the transmitter’s carrier frequency
error. Upper and lower limits must be entered in ppm (parts per
million).
Pass/fail limits are determined by using any applicable standard such
as:
EIA/TIA Standard: Frequency Requirements, Frequency Stability
Example
If you desire that the carrier frequency should be maintained within
±2.5 parts per million (ppm) of any assigned channel frequency, enter
2.5 as the Lower Limit and 2.5 as the Upper Limit.
