3.2.1.6.7 Gate Array Pulse Length Generator
The Pulse Length Generator Function (Chapter 9, Figure 9.1.21) provides the
length of the generated pulse in accordance with the previous selections.
This function is performed by the Gate Array, which generates the signals
TRPS and TRPL when:
−
the signal TR is active
−
the signal HVOK is low
−
the 50 MHz clock is present
−
the signal RESET is high
−
the signal LINE is true
−
the signal SLK is high
−
the signal ANTBLK is high
−
Main Line ≥ 40VDC
