Triple Output, 160 Watt Power Supply

SCPI Status Registers
All the SCPI instruments execute the status register operations in the same way. The status system records the various instrument states into three register sets: status byte register, standard event register and questionable status register sets. The status byte register records the advanced summary information reported by other register sets. The SCPI status systems of the DP800 series multi-channel models.

SCPI Command Overview
SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming language that is built upon the standard IEEE488.1 and IEEE 488.2 and conforms to various standards (such as the floating point operation rules in IEEE754 standard, ISO646 7-bit coded character for information interchange (equivalent to ASCII programming)). This section introduces the syntax, symbols, parameters and abbreviation rules of the SCPI commands.

Build Remote Communication
You can build the remote communication between DP800 and PC over USB, LAN, RS232 or GPIB (option, can be extended via the USB-GPIB interface converter) interface.

Remote Controls Methods

• User-defined Programming - You can program and control the instrument using the SCPI (Standard Commands for Programmable Instruments)
• Send SCPI Commands via the PC Software - You can control the power supply remotely by sending SCPI commands via the PC software (Ultra Sigma) provided by RIGOL.

Overview

The Rigol DP831 is a very high quality programmable laboratory power supply with three switchable outputs (+8 V/5 A, +30 V/2 A and -30 V/2 A) and a maximum power output of 160 W.

Like all Rigol devices, the power supply features a very well constructed and easy to use interface, which also offers comprehensive ease-of-use functions, such as programmable voltage curves. The menu has an intuitive structure.

The Rigol DP831 features a relative large (8.9 cm / 3.5") and easy to read TFT monochrome display. In addition to the normal digital displays for voltage, current, and power, these values can also be displayed as signal curves. A timer control can be used to set the output signal to different values in up to 2048 steps.

Special features

• Clearly Arranged Display - all important data such as voltage, current, power, and limit values can easily be displayed on the display with a diagonal size of 8.9 cm (3.5") and a resolution of 320x240 pixels.
• Output Monitoring - the monitor can monitor the current output state of the instrument. When the user-defined monitor condition is met, the instrument executes the corresponding operation according to the setting in "Stop Mode", like showing a warning, shut off the output or produce a beep sound.
• Display Signal Curves - changes in the measurement values and settings can be presented very well and in real time using the integrated signal curve display. This makes it possible to detect things like current draw peaks, for example when the current limit is adjusted.
• Programmable Timer - the voltage and current settings can be changed automatically with a timer control. Up to 100 settings can be stored for this purpose, and then activated one after another for variable intervals (specified in seconds).
• Output Analysis - the analyzer can analyze the file recorded and provides the analysis results, including the number of groups, median, mode as well as the average, VAR, range, minimum, maximum and mean deviation of the voltage, current or power of different channel.
• Trigger Output - the rear panel of DP800A provides a digital I/O interface (as shown below) which supports trigger input and trigger output. The 4 data lines are mutually independent and can be used as trigger input line or trigger output line separately.
• Excellent connectivity and remote control via SCPI / LabView
  • The Rigol DP831 can be controlled remotely with SCPI commands through a variety of interfaces
  • The following interfaces are available: LAN, USB and GPIB (optional)
  • Control of the device can be integrated in your own applications, or by using LabView via these interfaces.
