System test configuration
SAT
The unit tested was configured with all hardware options present. Since the unit, under its
normal operation, does not transmit data periodically, for emissions measurements, the SAT
was programmed with special test software to transmit packets continuously at 17dBm output
power, duty cycle (67.7%) with power amplifier enabled for FCC test requirement only.
Normal operation duty cycle, assuming worst case, one event per second is less than
0.5% (5mSec transmit time per 1 second).
Tag wearing
SA91/004135 and SA91/004035 should be worn on the waist belt with crocodile clip as shown
in picture below.
Theory of operation
The SAT method of communication is synchronized event based reporting, the SAT spends
most of its time in low power sleep mode. Event could be GPS location, motion start and stop,
PBC found and which one. When an event happens, the SAT sends a report to the base
station. In order to avoid packet collisions and associated detection methods, the system uses
a synchronous protocol, that is, An SAT can transmit data only after receiving a
synchronization signal from the base station.
