2.2.8 Power Supply
The Power Supply takes the 24V AC power it receives from the transformer and
converts it to a variety of DC voltages (+ 5.5V, +5V, +12V, -12V, and +10.5V).
These voltages are used by a variety of instrument components, including the PC
module, measuring unit, lamp, display, and optional equipment (TWM, STM etc.).
The Power Supply receives command signals from the DSP Board via the I
2
C bus.
The I
2
C decoder processes these signals and controls the lamp and display
accordingly. For example, the lamp and display backlight can be placed in power
saving stand-by modes, the display itself can be extinguished during certain
sequences such as the initial instrument boot-up procedure.
