HP / Agilent 6627A Precision dc Power Supply
Four isolated outputs are integrated into one package,
conserving rack space and GPIB addresses. Most of the outputs also provide dual ranges, for
more current at lower voltage levels. The outputs can be connected in parallelor series to further increase
the flexibility that these products offer the system designer. Programming is done using
industry standard SCPI commands. Test system integration can be further simplified be using
the VXI Plug & Play drivers. These power supplies help reduce test time
with fast up and down programming, which is enhanced by an active down
programmer which can sink the full rated current.
These power supplies are very useful on the R&D bench. The accuracy of both the
programming and the measurement systems allow precise control and monitor-ing of prototype bias power.
The extensive protection features protect valuable prototypes, including
very fast CV/CC crossover. The power supply can be controlled from either
the front panel keypad or, for auto-mated testing, from the GPIB.
Features:
- Precise V & I programming and readback
- Fast up and down programming
- Extensive protection for DUTs
- Easy to integrate into a system
