Test Specifications
24 — 25 TX Power/Time Template Neg and Pos Peak Flatness
24 — 25 TX Power/Time Template Neg and Pos
Peak Flatness
Description These specifications set the amplitude envelope limits for flatness
measurements taken over the useful bits of a GSM burst.
If a selected limit is exceeded, an “F” (for fail) will be displayed next to
the TX neg peak flatness or TX pos peak flatness
measurement result.
Default values • The default value for neg peak flatness is
−1 dB.
• The default value for pos peak flatness is 1 dB.
Example If you want your test procedure to report a failure when the flatness of
the amplitude envelope exceeds
±0.5 dB you would enter:
•
−0.5 in the lower-limit column and 0 in the upper-limit column for
specification TX power/time template neg flatness, and
• 0 in the lower-limit column and 0.5 in the upper-limit column for
specification TX power/time template pos flatness.
Limits are in units of dB.
