Test Specifications
34 — 35 TX RACH Power/Time Neg and Pos Peak Flatness
34 — 35 TX RACH Power/Time Neg and Pos
Peak Flatness
Description These specifications set the amplitude envelope limits for flatness
measurements on a RACH (Random Access Channel) taken over the
useful bits of a burst.
If a selected limit is exceeded, an “F” (for fail) will be displayed next to
the TX RACH neg pk flat or TX RACH pos pk flat measurement
results.
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 amplitude
flatness exceeds
±0.5 dB you would enter:
•
−0.5 dB in the lower-limit column and 0 dB in the upper-limit
column for specification TX power/time template neg
flatness, and
• 0 dB in the lower-limit column and 0.5 dB in the upper-limit
column for specification TX power/time template pos
flatness.
Limits are in units of dB.
