1650A Analyzer/10449A升级后程序或文档在哪？

根据我在网上找到的一些非常古老的文档，10449A包括RAM，ROM，软件和手动插入。
我有一些旧的目录，这是在'92目录中，但不是'95。
到那时，1650年已被1660年取代鉴于这是大约20年前，在安捷伦存在之前，我怀疑任何部分仍然存在，但可能有文件。
如果您查看Agilent网站，则会列出可能包含该文档的供应商列表。
祝你好运，Al

  According to some VERY old documentation I found online, the 10449A included RAM, ROM, software, and manual inserts. I have some of the old catalogs, and this was in the '92 catalog, but not '95. By then the 1650's had been replaced by the 1660's

Given that this was about 20 years ago, before Agilent existed, I doubt that any of the pieces still exist, but there might be documentation. If you look on the Agilent website, there is a list of vendors that might have the documentation.

Good luck,
Al

信不信由你，我是1989年和1990年1650A和1650B的部门支持工程师。我的记忆有点模糊，但这是我的回忆。
1650A只有定时模式。
10449A是添加状态模式的升级。
升级是RAM，ROM（正如Al在他的回复中所述）软件升级。
我记得1650B ROM不能使用;
PC板升级和其他重大设计变更。
没有PC板的变化。
信号来自相同的探头，但新功能是显示功能，然后启用反汇编。
我会说有10年前。
一个想法是在雅虎HP_Agilent用户组发布一个问题，因为有些人有旧部件;
但这是一个非常独特的产品升级，以低销量出售。
仍然留下深刻印象的是这些产品在25年后仍然有效！
希望学生们喜欢测量......迈克

  Believe it or not, I was the Division Support Engineer for the 1650A and 1650B in 1989 and 1990.  My memory is a little fuzzy, but here's my recollection.

The 1650A only had timing mode.
The 10449A was an upgrade to add state mode.
The upgrade was a RAM, ROM (as Al stated in his reply) software upgrade.
I recollect that the 1650B ROMs cannot be used; there was an upgrade of the PC board and other significant design changes.
There was NO PC board changes.  The signals came across the same probes, yet the new capability was a display feature that then enabled disassembly.

I would state there is 10 years ago.

One idea is to post a question at the Yahoo HP_Agilent user group as some people have old parts; but this was a pretty unique product upgrade that was sold in low volume.

Still impressed these products are still functional after 25 years!

Hope the students enjoy making measurements...

哇，非常感谢回复！
我很感激阅读它们。
在1650B上试验1650B和1652B系统以及pvtest应用程序后，断开示波器电缆并观察报告的错误等，看起来它们在引擎盖下完全相同。
ROM中的开机自检也不会试用HPIB或示波器（pvtest似乎需要测试示波器板。）确认不应对电路板进行任何修改非常有用。
1630系列的一次固件更新（我们的是1984年，仍然可以使用并且经常使用）需要切割痕迹并添加导线。
我们尝试升级几乎与整个图片的一小部分一起工作，阻止系统启动。
RAM芯片不再制造，但我购买了一些回收芯片，只需几美元。
将插座和旁路电容器添加到1650A中未填充的封装后，它被重新组装并且工作正常。
然后用1650B设置切换ROM，机器没有通过RAM测试。
然后RAM芯片安装在新的插座中，机器通过了RAM测试。
它也通过了所有的自我测试，包括收购，门槛等。
它失败的是磁盘测试，它无法启动。
磁盘控制器发生了一些变化。
切换回1650A 1.00 ROM设置，一切正常。
那么，磁盘控制器的内存地址或粘合逻辑是否已更改，或者是否已使用其他芯片？
当机器开启时，磁盘驱动器将寻求跟踪'0'，但这是磁盘驱动器中唯一的响应。
之后，LED不会点亮，主轴永远不会转动。
希望正确的ROM将允许机器读取磁盘。
顺便说一句，即使惠普的旧设备编程基础设施早已不复存在，也许公司图书管理员可以找到旧部件的数据文件。
首先尝试在野外找到一个可能最容易，我会这样做。
再次感谢＆amp;
干杯!

  Wow, Thanks so much for the replies!  I'm very grateful to read them.  

After experimenting with the 1650B and 1652B system and pvtest applications on the 1650B, disconnecting the oscilloscope cable and observing errors reported, etc., it looked like they're all the same under the hood.  The power on self test in the ROM do not try out the HPIB or oscilloscope, either (pvtest seems required to test the scope board.)

It's very useful to have confirmation that there shouldn't be any modifications to the board.  One firmware update for the 1630 series (ours is from 1984 and still works and is used often) required cutting a trace and adding a wire.  Our attempted upgrade almost worked with a very small part of the whole picture preventing the system from booting.

The RAM chips are no longer made, but I purchased some recycled chips for a few dollars.  After adding sockets and bypass capacitors to the unpopulated footprints in the 1650A, it was reassembled and it worked fine.  Then the ROMs were switched with the 1650B set and the machine did not pass the RAM test.  Then the RAM chips were installed in the new sockets, and the machine passed the RAM test.  It passed all the self-tests for the acquisition, threshold, etc. too.

The one it failed is the disk test and it wouldn't boot.  Something was changed about the disk controller.  Switching back to the 1650A 1.00 ROM set, all worked fine.  So, the memory address or the glue logic for the disk controller changed, or a different chip may have been used?  The disk drive will seek to track '0' when the machine turns on, but that is the only response ever seen from the disk drive.  After that the LED won't light and the spindle never turns.

Hopefully the right ROMs will allow the machine to read the disk.  By the way, even if HP's old device programming infrastructure is long gone, perhaps a corporate librarian would be able to find data files for old parts.  It's probably easiest to try to find one in the wild first, and I'll do that.

Thanks again & Cheers!
