5.4.7 Miscellaneous Nuclei
5.5 Test instructions SACD mono board
5.5.1 General
Impedance of measuring-equipment should be > 1MΩ
Most tests have to be done by software commands.
Together with the software command you will find a Ref.#
nbr. This is the number of the diagnostic nucleus used for
this test. More detailed information can be found in the
description of the command mode interface.
Levels: Most measurements are digital measurements.
The high and low levels in this document got to have next
specification: low : < 0.3V (LVTTL) high : > 3.0V
(LVTTL) LOW : < 0.4V (TTL) HIGH: > 4.5V (TTL)
All voltages marked with “stby” have to stay on during
standby.
Because all clocks are derived from the SACD clock
(384FS_in) from the DAC board, this board should
always be connected to the mono board.
The linear power supply is switched on/off by the
STB_OUT signal from the mono board to the DAC board.
5.5.2 General start-up measurements
Supply check:
1. Measure the voltages on the pins of the connector 1600
with a multimeter.
2. Also check the following power supplies:
Testpoint F608: +3V3 (5%. (Check IC7605 in case of failure)
Testpoint F632: +3V3 (5%. (Check IC7622 in case of failure)
Testpoint F101: +9V (5%. (Check IC7109 in case of failure)
1. Current at the input of the power supply
Check the supply currents to be sure that there are no major
failures on the board.
Measure the currents flowing toward the mono board using a
Tektronix AM503B current probe on the wires between the
switch mode power supply and the connector 1600.
