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 DP800 Series Power Supplies combine the ability to source, analyze, and coordinate over time in a powerful new package. The DP800 Series is a family of linear power supplies systems with 3 outputs and up to 195 Watts in total. With one channel isolated users can reconfigure instruments into any number of systems or applications.

Built in V, A, and W measurements make power monitoring easy, but additional wave tracking, timing, and analysis features means there are even more ways to use the supplies. New digital triggering between instruments also makes it possible to reliably combine and connect supplies together. Intuitive to use for everything from education labs to the R & D bench, the DP800 family of power supplies provide incredible value for any application.

Typical Applications

R&D Iab General purpose testing
Quality Assessment inspection
Bias power for RF/MW circuits
Automotive electronic test
Production testing
Device or circuit characterization and troubleshooting

Great split rail PSU

5.0

So far, this PSU is accurate and precise. Wish that CH1 was 15V instead of 8V, but this isn't my only PSU so not a huge hang up. Love the different settings for the display and tracking channels 2 & 3 is a very convenient feature. Another cool option is the dashboard (dial) toggle. The only drawback is that I don't think you can modify the scale limits. Eg - power full scale is 50 watts which makes it impossible to read lower values (<5 watts). But I guess that is what the digital readout is for.

This was my first Rigol purchase and I love it! When compared to other brands, for the same money, this is the leader for sure! Using it about 1 year, it works great and I haven't run into any problems! So I purchased a second Rigol product DL3021A - what a great bargen!

Great Supply

4.0

I am very happy with this supply so far. It works as advertised. I really like the option for remote control and also the ability to program output waveforms. This should make lab testing much easier for me. The only complaint I have so far is that the current limit settings are a little confusing. There are actually TWO ways that current is limited - one is through the familiar constant/max current function that is present in most power supplies. However, this supply also has a "overcurrent" protection setting which actually shuts the output off if it is tripped. It's important to keep these straight or the behavior will be confusing.

Overall Impression

5.0

I have used this power supply for more than 6 months. The positive and negative supply are very handy if you always deal with op amp stuff. For most of users, even professional users, this is more than good enough for them. Thinking about using it for many years, this price is the best I can find for power supply that have positive/negative rail supply.
