SYSTEM PERFORMANCE
A significant number of the system performance parameters depend heavily on the RF/Analog
circuits. The information presented here therefore represents onlyt an estimate of these parameters.
PARAMETER
ESTIMATED PERFORMANCE
Oscillator Stability
Depends primarily on the analog circuit but
<
15 ppm over terperature
range and aging (for 1 dB sensitivity degration ) should be achievable
Acquisition Time
<100 bits average
<200 bits for 99.9% probability of acquisition at S/N of 2 dB
(applies for first burst only)
Interference Immunity in

±
1.365 MHz)
