ASPIRE-400
OR
2 For an antenna gain less than 6 dBic the power at the output of the
power amplifier is 9.1 dBW plus the ORT PA to antenna loss value
(6) The ACD PIMBIT points the antenna based on the:
(a) The azimuth and elevation settings stored in the ORT; and
(b) The hemisphere where the test is being performed.
(7) The ACD PIMBIT determines the PIMBIT pass / fail status by comparing the PIMBIT test
results with the following parameters stored in the ORT:
(a) PIMBIT failure threshold
(b) PIMBIT antenna beam pointing angles failure threshold, and
(c) PIMBIT measurement sample discard ratio.
(8) The ACD aborts PIMBIT when commanded by the interface that invoked PIMBIT.
D. PIMBIT Log and Records
(1) The ACD maintains a PIMBIT Log that:
(a) Supports a minimum of 20 Historical PIMBIT Records
(b) Store the most recent Historical PIMBIT Records should the capacity be
exceeded.
(2) The ACD stores the following PIMBIT test header information in the PIMBIT Log:
(a) Time and Date of test
(b) Aircraft Tail Number
(c) ICAO address
(d) Antenna serial number (as available).
(3) The ACD stores the following PIMBIT test result information in the PIMBIT Log:
(a) Hemisphere in which test was conducted (Northern or Southern)
(b) PIMBIT ORT item settings
(c) Test frequencies used
(d) Aircraft-relative azimuth and elevation antenna beam pointing angles
(e) Average channel degradation results for each antenna beam
(f) Standard deviation (1σ) of the measurement results of each antenna beam
(g) Pass/Fail indication for each antenna beam
(h) Average channel degradation across all beams
(i) Overall Pass/Fail indication
(j) Antenna serial number (as available).
E. Audio Loop Back Test
(1) When commanded from the web GUI, the ACD does the following without the need to be
connected to the satellite network:
