| Anyone have an HP / Agilent E1406A VXI controller with IBASIC? |

For the benefit of anyone who is reading this thread, I'd like to mention that there is a VISA based download utility for downloading DSCPI drivers to Flash and to RAM. This works on modern systems quite well. It can be found in the archive mentioned earlier at ftp.keysight.com/mpusup/E1406A/visadownload/visaDownload.cab I also have a question regarding the Memory usage of the E1406A with IBasic installed. I picked up up an Option 020 module and it has IBasic installed, with the larger Flash ROM, but the RAM only reports about 327kB (DIAG:DRAM:CRE? MAX,MAX) with no other instruments installed. I thought it should be close to 1MB. As there is plenty of Flash for my drivers, I would not care much, but it seems this RAM is also needed to support running the instruments. It seems that about 64kB is needed for each register based instrument , so as it is it could not support a full 13 slot mainframe. Does the "Ibasic instrument" consume the extra RAM that should be installed? Or is it possible that some of the RAM is bad? I would think the self test would fail in that case. If someone else who has a similarly configured card could let me know what they get from "DIAG:DRAM:CRE? MAX,MAX" with no other instruments I would appreciate that! |

I took apart the module and discovered that all the RAM was present, but JM5 was set which specified 0.5M RAM. When I changed it to JM3 (1.0M) all the RAM was able to be seen. So either the module was mis-configured from the factory, or the OPT 020 didn't include OPT 010. |
