Specifications

due to its extended voltage
and current range, can produce
voltage and current combina-
tions in the range of a 250 W
non-autoranging power supply.
The flexibility of autoranging is
useful when the DUT operates
over a wide range of voltages,
when the ATE system needs to
test a wide range of DUTs, or
when margin is needed because
the ATE power supply must
be selected before final DUT
power requirements are
determined.
High-Speed Test Extensions
To make your testing go even
faster, the N6750/60 offer
High-Speed Test Extensions
(HSTE). This enhancement to
the N6750/60 DC Power Modules
extends the capabilities to
include features similar to
a built-in arbitrary waveform
generator and a built-in
oscilloscope.
Through the LIST mode of
HSTE, you can download up
to 512 setpoints of voltage and
current. In LIST mode, you can
program the output to execute
a LIST of voltage and current
setpoints. For each setpoint, a
dwell time can be specified and
the power supply will stay (i.e.,
dwell) at that setpoint for the
programmed dwell time value.
For each setpoint in the LIST,
you can have a different dwell
time from 0 to 262 seconds
with 1 microsecond resolution.*
Then, you can trigger the mod-
ule to begin executing the list.
The module will step thru the
list, staying at each setpoint
for the programmed dwell time,
and then it will move on to the
next point. This speeds up
execution by removing the
computer I/O from the process.
The result is an output that
automatically changes according
to the programmed list, just
like an arbitrary waveform
generator.
* Note that the output response
time is less than 5 millisec-
onds per voltage change,
so steps of less than 5 mil-
liseconds will not achieve
their final output voltage
value before moving on to
the next step. This is useful
when trying to create a
smooth waveform.
