Can anyone help me with this please? I wanted to add the facility to adjust the current at which the zener voltage is read, not a big problem and it works fine apart from one tiny niggle that I cannot puzzle out. The maximum current is set at 10mA, the minimum at 1mA, the Max and Min buttons work fine but if I manually enter 10mA on the keypad it will not allow it saying "Value is greater than 10.0mA" If anyone could try it on their BB3 and see if it does the same. I am running 1.7.1 with a R2B4 CPU module If I am doing something stupid please forgive me as I am a crusty old hardware engineer. The extenstion of the txt file needs changing to .res to load. Thanks in advance. |

I can only reproduce this at max 10mA, other values I tried don't have this behaviour. It also gives the error if you type 9.9999999mA with a max of 10mA... My conclusion: Some kind of conversion/rounding threshold anomaly. Worth making a GitHub issue for. Workaround I can give for now: 'DISP:INPUT? "I_SET",NUMBER,AMPER,0.001,0.01000001' (hitting max will also give 0.01) |

Maybe this is not my fault, I just like things to work correctly. Thank you again, regards Mike |

Yesterday we released the latest version of EEZ Studio v0.9.88 which now includes an experimental R&S®VISA interface. A short How to article has also been published describing how to easily start collecting screenshots from DSO and other equipment. It is currently tested with Rigol DS1074Z and Siglent VNA1015X. Thanks in advance to everyone who will invest some time and test EEZ Studio with their instruments. Feel free to report issues on GitHub issue tracking, your feedback will help us make it better and useful for as many instruments as possible. |
