You often need to collect data from sensors.. Sure, you can get a 3458A for each temperature you want to measure, but sometimes $3 solution with ~1mK resolution could be enough :) |

If I need a solution for a few hours I prefer to use standard parts (This includes DIY sensors) to set it up, but when used for longer time a simple program in a microprocessor may be a much better solution. Because I have a pile of PC's (laptops) and I need the final result on a PC, I usually use a PC for my data collection. |

Grapher - works nice! My "nice to have" suggestions: 1. the formatting of the Y axis - would be great to have constant number of decimal digits (like 10.123455, 10.123450..) 2. ppm math - like PPM (Sample - Y)/Y *1e6, or something like that.. |

Wonderful job and thank you for sharing! 8) This works fine on my HP3456A and an AR488 interface. I had to activate the flow control via xon / xoff otherwise the connection failed systematically! |

Nx-1997 Thank you for sharing. IMO you have created a nice simple intuitive and easy to use GUI. Within minutes I was able to have 3x 34401A's logging data with a real time graph. Exactly what I was looking for. Question If I want to send a command to turn off the VFD display, is there a way to send a command while logging? |
