Atec Agilent-6680 User Manual
Reliable DC power for manufacturing
test and long-term burn-in
This series of 5000 watt DC power
supplies has the exceptional, proven
reliability that test system engineers
look for. It also has the features
needed for easy test system
integration.
Programming of the DC output and
the extensive protection features
can be done either from the front
panel or using industry standard
SCPI commands, via the GPIB.
Using the serial link, up to 16 power
supplies can be connected through
one GPIB address. Test system
integration can be further simplified
by using the VXIPlug&Play drivers.
The output voltage and current
can also be controlled with analog
signals. This is helpful for certain
types of noisy environments, and
also immediate reactions to
process changes.
The 6680A Series has extremely
low ripple and noise for a 5000 watt
DC power supply. This helps the
built-in measurement system make
extremely accurate current and
voltage measurements.
Selectable compensation is provided
for problem-free powering of
inductive loads.

Supplemental Characteristics
for all model numbers
DC Floating Voltage: Output terminals can
be floated up to ±60 Vdc maximum from
chassis ground
Remote Sensing: Up to half the rated
output voltage can be dropped in each
load lead. The drop in the load leads
subtracts from the voltage available for
the load.
Command Processing Time: Average time
required for the output voltage to begin
to change following receipt of digital data
is 20 ms for power supplies connected
directly to the GPIB
Modulation: (analog programming of
output voltage and current):
Input Signal: 0 to –5 V for voltage,
0 to +5 V for current
Input Impedance: 30 kΩ/or greater
