Description
The Agilent E3631A power supply features a combination of programming
capabilities and linear power supply performance that makes it ideal for
power systems applications. The triple power supply delivers 0 to ± 25 V
outputs rated at 0 to 1 A and 0 to +6 V output rated at 0 to 5 A. The ± 25V
supplies also provide 0 to ± 25 V tracking output to power operational
amplifiers and circuits requiring symmetrically balanced voltages. The 0 to
± 25V outputs track each other within ±(0.2% 20 mV) in the track
mode. The ± 25V outputs can also be used in series as a single 0 to 50 V/1 A
supply.
The voltage and current of each supply can be adjusted independently from
the front panel or programmed over the GPIB or RS-232 interface. Using the
front panel keys and the control knob, you can adjust the voltage and
current of a selected output; enable or disable track mode; store and recall
operating states; enable or disable three outputs; calibrate the power supply
including changing the calibration security; return the power supply to local
operating mode; and configure the power supply for remote interface
operation.
From the front-panel VFD (vacuum-fluorescent display), you can monitor
actual values of output voltage and current (
meter mode ) or voltage and
current limit values ( limit mode ), check the operating status of the power
supply from the annunciators, and check the type of error from the
displayed error codes (messages).
When operated over the remote interface, the power supply can be both a
listener and a talker. Using an external controller, you can instruct the
power supply to set outputs and to send the status data back over the GPIB or
RS-232. Readback capabilities include reading back output voltage and
current; present and stored status; and error messages. The following
functions are implemented over the GPIB or RS-232:
• Voltage and current programming
• Voltage and current readback
• Enable or disable track mode
• Present and stored status readback
• Programming syntax error detection
• Voltage and current calibration
• Output on or off
• Self-test
