4.1.2.
The relay switching matrix plays a vital role in connecting the selected test
sources and measurement circuits to the appropriate nodes during testing.
This matrix uses high-speed, high-voltage reed relays that are robust enough to
handle the 7000V test voltages used in high-pot tests, while also capable of
switching extremely small voltages and currents in other tests.
Controlled precisely by the processors, these relays avoid arcing and are
designed for millions of operations.
The AT Series Testers are based on a two-processor design:
• A standard microprocessor which acts as controller, controls the test
sources, and drives the relay matrix, the keyboard and display, and the
various interfaces.
• A fast-digital signal processor that performs the measurements.

PROCESSORS
There are six different test sources within the AT5600.
The processors select which one is to be connected to the relay matrix as each
test is executed.
