I have wanted the Rigol DP832A for quite some time but was concerned at the inadequate cooling in the early models of the LM317 voltage regulator. Knowing that the revised boards were now coming on stream I decided to take the plunge and was more than surprised and impressed with the help offered by Telonic systems who were totally up front about the issues and were more than happy to help me get exactly the machine I wanted with the revised board and also the larger heatsink. First rate service - sincere thanks!
The PSU is an excellent piece of equipment - performs very well, does not suffer from undue noise and the output settings are absolutely correct as measured with my accurate Agilent 34461A. I find the user interface easy to work with and the info on the LCD screen very helpful. Well built equipment that will be a pleasure to use for years to come I am sure.
