Agilent 6650A Series Single-Output,
500 W DC Power Supplies, GPIB
Data Sheet
Speed and accuracy for test optimization
• Fast, low-noise outputs
• Analog control of output voltage and current
• Fan-speed control to minimize acoustic noise
• Built-in measurements and advanced programmable features
• Protection features to ensure DUT safety
This series of 500 W linear-regulated
DC power supplies is designed to maximize the throughput of DUTs through
the manufacturing test process with
fast up and down programming time.
Valuable assemblies can be destroyed
by a minor component failure that
causes a surge of current to flow
into the DUT. Fast protection features, including fast crowbar, mode
crossover protection, and the ability
to connect the protection circuitry of
multiple power supplies can increase
production yield.
Programming of the DC output and
the 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 be 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.
Lab bench use is enhanced by the fan
speed control, which helps to minimize
acoustic noise.
