Figure 3.22 Schematic of the X-E board
The X-E board also carries the drivers for DynCor and threshold signals. These signals are copies
of the energy signal and are adjustable in amplitude. The amplitude adjustments are performed in
analog multipliers, controlled by DC voltages from dedicated DAC's on the tune board.
The digital values written to the DAC's are contained in the tuning tables.
Note that the analog multipliers are supplied from +5 V and –5 V linear regulators located on the
Y board.
