Specifications

While some applications
require fast risetime and/or
falltimes, some devices can
actually be harmed by a power
supply that is too fast. For
these cases, the LIST mode
of the N6700 can be used to
“slow down” the output. For
this application, you create a
slow ramp of output voltage
by dividing the total voltage
excursion into a smaller number
of steps and dwell at each step
for some amount of time. For
example, let’s say you need to
go from 0 V to 50 V in 500 mil-
liseconds. For this case, the
output programming response
time specification of 5 millisec-
onds is too fast. To slow down
the output, you could use LIST
mode and program 50 steps
of 1 volt per step, and dwell at
each step for 10 milliseconds.
The result will be a ramp from
0 V to 50 V in 500 milliseconds.
HSTE also provides an
oscilloscope-like digitizer built
into the power module to
capture voltage and current
measurements of up to
4096 points at up to 50,000
measurements per second.
