我有一个N9938A 9 GHz 3端口Agilent PNA。
有人说这有一个超级电容,但服务手册没有提到任何超级电容。 但是说有锂电池。 它的问题在于,如果它已经断开主电源一段时间,它将无法正常通电。 它进入无限循环,开始一秒钟,然后停止,然后加电一秒钟。 。 我发现很难相信这是由于电池或超级电容,但也许我错了。 达 以上来自于谷歌翻译 以下为原文 I have an N9938A 9 GHz 3-port Agilent PNA. Someone has said that this had a supercap, but the service manual makes no mention of any supercap. but says that there's a lithium battery. It has a problem in that it will not power up properly if it has been disconnected from mains power for a while. It goes into an infinite loop of starting for a second, then stopping, then powering up for a second. . I find it hard to believe that this is due to a battery or supercap, but maybe I am wrong. Da |

由于我没有回应,我以为我会再问一次。
安捷伦是否在PNA系列中使用“超级电容”? 特别是N3383A(3端口,9 GHz),我知道超级电容器在早期的HP VNA中使用,因为当时缺乏合适的电池,但即使是我以后的HP 8720D也有电池,所以我觉得有点奇怪 较新的N3383A PNA将使用超级电容。 戴夫 以上来自于谷歌翻译 以下为原文 Since I got no response, I thought I'd ask again. Did Agilent use a "supercap" in the PNA series? In particular an N3383A (3-port, 9 GHz) I know supercaps were used in early HP VNAs due to the lack of decent batteries at the time, but even my later HP 8720D has a battery, so I find it a bit odd that a newer N3383A PNA would use a supercap.

60user7 发表于 2018-10-29 08:37 也许在这个论坛上来自Keysight的少数人不知道这一点,他们不想问一个知道的人。 此外,如果我没有弄错,我认为某些Keysight PS是由第三方制作的。 但我告诉你,为了存储数据,我不这么认为,但我昨天正在阅读它,它们在PS中使用看看这篇文章。 http://cds.linear.com/docs/en/lt-journal/LTJournal-V22N1-08-df-LTC3226-AshishKirtania.pdf编辑:theamberco于2014年10月21日下午6:31 以上来自于谷歌翻译 以下为原文 Maybe the few people from Keysight in this forum dont know about that and they dont want to ask someone who knows. Also if I am not mistaken I think some of the Keysight PS are made by third parties. But I tell you that for storing data I dont think so but I was reading yesterday about it and they are use in PS look at this article. http://cds.linear.com/docs/en/lt-journal/LTJournal-V22N1-08-df-LTC3226-AshishKirtania.pdf Edited by: theamberco on Oct 21, 2014 6:31 PM |

60user7 发表于 2018-10-29 08:37 任何年份或风味的PNA都不使用超级杯。 只有CPU有电池,而且只有RTC。 以上来自于谷歌翻译 以下为原文 PNAs of any vintage or flavor do not use supercaps. Only the CPU has a battery and that is only for the RTC. |
