HP8753B固件3.00校准丢失

问答对人有帮助，内容完整，我也想知道答案 0 我的HP8753B似乎是有序的，除了在进行任何类型的校准并保存到用户寄存器后，常量仅在上电期间保存。如果电源关闭并在几秒钟后再次打开，校准将丢失。用户寄存器的标志显示重新保存，因此似乎记得存在保存。另一方面，VNA记得选择了哪个校准套件并且正在使用中我几个月前更换了超级电容器。谢谢，Gianfranco 以上来自于谷歌翻译以下为原文 My HP8753B seems to be in order except that after doing any type of calibration and saving to a user register the constants are only saved during power on. If power is turned off and turned on again even after few seconds calibration is lost . A flag by the user register shows re-save so it seems to remember that there has been a save. On the other side the VNA remembers which calibration Kit has been selected and is in use I changed the super-cap few months ago. Thanks, Gianfranco 0

答案对人有帮助，有参考价值 0 回到那天，我们将一些东西保存到eeprom中，剩下的就是ram。我认为这些工具包已保存到eeprom，因为它们只是偶尔会发生变化，应该在很长的断电周期内保存。保存/调用状态数据处于ram状态。可能是一些公羊没有熬夜，而其他部分则熬夜超级上限。可能是他们都迷失了。我原以为重新保存标志是ram状态的一部分，但可能不是，或者可能是文件的名称保存在eeprom中，但数据是ram。我想很久以前就把它解决了。我会再次看看超级上限。以上来自于谷歌翻译以下为原文 Back in the day we saved a few things into eeprom, and the rest was ram. I think the kits were saved to eeprom as they were expected to be changing only occasionally and should be saved over a long power off cycle. The save/recall state data was in ram. It might be the some of the ram is not staying up while other parts is staying up with the super cap. It might be they are all lost. I would have thought that the re-save flag would be part of the ram state but is possible that it is not, or it might be the name of the file is saved in eeprom but the data is in ram. Too long ago to sort it out, I think. I would look at the super cap again.

I found in Chapter 10 pag 1 that it is written that the calibration date can be saved in the volatile memory or stored in the external disk. I do not have the external disk so it means that when I switch off the VNA the calibration data are lost. to solve the problem I can use the VNA.EXE of John Miles. Do you know if there is a " modern" alternative to the original external disk ? Thanks Gianfranco
