Introduction
This section provides the temperature and cooling
requirements for the 3070 / 79000 family systems. The
requirements are summarized in Table 5-1, and
discussed in detail in the remainder of this chapter.
Air Temperature Specifications
The 3070 / 79000 family board test system is designed
to operate uninterrupted in an area where the air
temperature is stable and in the range from 0 C to 40 C
(32 F to 104 F), as measured at the tester-to-fixture
interface.
The system has a built-in temperature sensor inside the
testhead, located on the ASRU card. This sensor
constantly monitors the temperature of the air that has
been drawn through the testhead after it cools the
system components. If the temperature sensor finds that
the air temperature inside the testhead has changed ±5 C
(±9 F) since the last time the system ran AutoAdjust All,
it will again run AutoAdjust All. Therefore, to ensure
uninterrupted use, it is important that the ambient room
temperature remain reasonably stable.
