| mrf245:
I bought some MS4630B with TRB (secondary receiver port), some of them are with issues such as LCD fault and panel broken. Now trying to repair it. |

Replacing the LCD panel shouldn't be hard. It is a standard VGA panel. |

Ressurecting my old thread... A couple of years ago I bought a Prologix ethernet to USB adapter to get screendumps from a Tektronix frequency counter. Since then I have created several other Python scripts to get screendumps from other equipment as well. The latest addition is the MS4630B. Or sort off... it turns out it can't really do a screendump over GPIB. It can only print. I have looked at printer emulation in software or hardware but that is either gone, expensive or requires different hardware. So I ended up creating a Python script that reads the data, plots a graph and saves it to disk. The attached script works OK for x-y plots both linear and logarithmic. It took a bit of effort to make Matplotlib use sensible numbers for the x axis. Polar and smitch charts aren't implemented. Some examples: Edit: added updated script which also shows the time + date and allows for an (optional) title using a -t option on the command line. |
