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 ± 25Vsupplies 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% output + 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
