Dut Routed To External Ate System (Default) - Equinox Systems ISPnano IV-ATE Series Hardware User Manual

4.4 DUT routed to External ATE System (default)

When the programmer is powered up but not running a 'Programming Project', the relay coils are
not energised so the 'Target System (UUT)' connections are routed via the 'Target ISP Port',
through the relays to the 'ATE Port' where they then connect to the 'External ATE / ICT System'.
The signal direction depends on the particular signal I/O line, GROUND or power line being routed.
The path of a single signal or passive power / GROUND line is shown in the schematic below.
Please note:
•
When the relays are not energised, the programmer electronics are completely isolated from
both the 'Target System' and the 'External ATE System'.
