Pass/Fail Limit (Specification) Descriptions

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.
