2.6.1.2 Burst Pulse Alignment Tool
0916-010
Figure 8 Burst Pulse Alignment Tool
The quality assessment of the transmit burst pulse and its precise alignment
at range zero are easy to do, either manually using this tool or
automatically using the burst pulse auto-track feature. This performs a 2D
search in both time and frequency space if a valid burst pulse is not
detected. The automatic tracking makes the AFC robust to start-up
temperature changes and pulse width changes that can effect the
magnetron frequency.
AFC alignment/check is now much easier since it can be done manually
from a central maintenance site or fully automatically.
