diagnostics. This means, that you cannot run any other
tests while performing the at-speed test.
The HCDPS atspeed loadboard is configurable and can
be adapted to each testhead configuration for HCDPS
boards at various positions.
To permit the HCDPS to be tested at maximum
current, each HCDPS pin is short-circuited. This test
can only be carried out in current mode.
DPS Connectivity and DPS Status checks are
described in the Standard Test Function Reference
manual, Part No. E7050-91012.
6. Trigger Circuit
As with the General Purpose and High Voltage DPS,
the High Current DPS can be triggered from a DUT
board with a 5V signal to start automatic
measurements.
The DPS is able to make any ADC measurement either
using the internally triggered mode with a firmware
command or externally triggered. In the external
trigger mode, a FIFO circuit with a size of 64k can
collect up to 32k of measuring data. There is one such
trigger input per device which floats and uses S_GND
as a reference.
