我有一个8720D VNA,其中给出日期和时间的时钟往往每月损失大约1天。
我猜这可能是一个电池运行平坦的sympton,虽然也许其他人知道不同。 更换电池有什么特别的预防措施吗? (我假设有一个电池,虽然它可能是一个超级电容,在这种情况下我可能会有更多的问题)。 我似乎无法在安捷伦网站上找到此VNA的维修手册,因此找出可能出现的问题并不容易。 DaveEdited:drkirkby于2012年11月27日上午5:28 以上来自于谷歌翻译 以下为原文 I've an 8720D VNA, where the clock which gives date and time tends to lose about 1 day per month. I'm guessing this might be a sympton of a battery running flat, though perhaps other know different. Are there any special precautions in changing the battery? (I assume there is a battery, though perhaps its a super-cap, in which case I might have more issues). I can't seem to find a service manual on the Agilent web site for this VNA, so it's not so easy to work out what might be the problem. Dave Edited by: drkirkby on Nov 27, 2012 5:28 AM |

有人让我知道有一个“服务指南”,请访问http://cp.literature.agilent.com/litweb/pdf/08720-90292.pdf如果从8720D上的安捷伦网页链接到那将是一件好事。
http://www.home.agilent.com/en/pd-1000002255%3Aepsg%3Apro-pn-8720D/microwave-vector-network-analyzer?cc=US&lc=eng无论如何,该服务指南提供了有关 电池,包括如何更换它。 它是A7BT1 Agilent部件号1420-0338(3 V 1.2AH,锂)。 唯一有点担心的是服务指南说仪器会产生一条错误信息,表明电池电量不足:*电池电量不足!

It's a A7BT1 Agilent part number 1420-0338 (3 V 1.2AH, Lithium). The only slightly concerning thing is that the service guide says the instrument can generate an error message indicating the battery is running low: *BATTERY LOW! STORE SAVE REGS TO DISK* *Error Number The battery protection of the non-volatile CMOS memory is in* *184 danger of failing. If this occurs, all of the instrument state* *registers stored in CMOS memory will be lost.

See the “Preset State and Memory Allocation,”* *chapter in the HP 8719D/20D/22D Network Analyzer User’s* *Guide for more information about the CMOS memory.* The fact I have not got that error, perhaps indicates the battery is not running low. Time to get out the DVM I think! Dave |
