8753D需要外部监视器P/N

它的后部没有VGA插座吗？
我希望任何可以同步到640x480的VGA输入的显示器都可以工作。
你看过手册了吗？
戴夫

  Does it not have a VGA socket on the rear? I would expect any monitor with a VGA input that can sync to 640x480 would work.  Have you looked in the manual? 

Dave

感谢Dave的回复;
是的我查看了手册;
后排有三（3）个BNC，标有红色，绿色，蓝色;
手册指出显示器需要满足以下要求：显示器必须兼容分析仪的25.5KHz扫描速率和视频电平：1 Vp-p，0.7V =白色，0V =黑色，-0.3V同步，同步
在绿色。
我试过一台标准显示器，但它不起作用;
只是找那些已经挂上显示器的用户，可以告诉我什么有效！
谢谢



     以下为原文

  Thank Dave for your reply; Yes I have looked at the manual; the rear out put has three (3) BNC's, labeled red, green, blue; the manual states that the monitor needs to have the following requirements:
the monitor has to be compatible with the analyzer's 25.5KHz scan rate and video levels: 1 Vp-p, 0.7V =White, 0V =Black, -0.3V  sync, sync on green.

I have tried a standard monitor but it won't work; just looking for users out there that have hooked a monitor up before and can tell me what works!

Thanks

可以接受列出的视频信号的监视器非常罕见且昂贵。
简单的事实是，这个标准是在1980年左右创建的，它只是普通的OLD而且已经过时了。
正如您所注意到的，VGA显示器无法工作。
除非您能找到有效的显示器，否则我猜你最好的选择是购买旧的PNA，例如E8356A 57A或58A（3,6,9 GHz）。



     以下为原文

  Monitors that can accept the video signals listed are very rare and expensive.  The simple fact is that this standard was created around 1980 and it is just plain OLD and outdated.  As you noticed, VGA monitors will not work.  

Unless you can find a monitor that works, my guess is your best bet would be to purchase a used older PNA, such as the E8356A 57A or 58A  (3, 6, 9 GHz).

我认为HP 8720D会有VGA，就像我的8753ES一样。
HP必须在8753D时间和8753ES时间之间从单独的BNC更改为VGA连接器。

一些VGA显示器将同步绿色，但任何人都猜测你如何找出哪一个。
我建议尝试其他显示器。
你可能会找到一个有效的。
我认为有各种各样的适配器也可以这样做，虽然我不知道哪种方法有效，哪些方法没有。
您可以在绿色和VGA的同步输入之间尝试一个电容。
我不知道你要去的是水平同步（引脚13）还是垂直同步（引脚14）。
我试图尝试1 nF，如果不起作用尝试10 nF，如果不起作用尝试100 nF，如果这不起作用尝试1 uF，也许去10 uF。
如果你不能让它发挥作用，我想我会放弃。
我自己从来没有这样做过，但我很确定我已经读到人们制作简单的适配器，只需要一个电容就可以将同步脉冲输出。
你可以试试惠普/安捷伦雅虎集团https://groups.yahoo.com/neo/groups/hp_agilent_equipment/info有很多人在那里保留旧设备。
8753D是现代的一些设备的标准人们在那里活着！
我的配合买了一个适配器，它允许将HP 70000模块化测量系统的输出放在PC上。
关于这一点的好处是可以捕获图像，从而从中生成报告。
我不知道HP 70000系列是否使用3 x BNC，但我怀疑它确实如此。
我不能轻易绕过我的后面去看。
但我知道他的适配器非常昂贵，但他认为值得的是，他可以捕获屏幕截图并复制/粘贴到客户的报告中。
>谢谢如果你在这里没有得到任何更多信息，我肯定会尝试惠普/安捷伦雅虎集团，但我也会尝试其他显示器，并在电池周围试图将同步脉冲送入显示器
。
祝你好运，如果找到解决方案，请务必将其发回。

I thought the HP 8720D would have VGA, like my 8753ES. HP must have changed from separate BNCs to a VGA connector between the time of the 8753D and the time of the 8753ES. 

> I have tried a standard monitor but it won't work; just looking for users out there that have hooked a monitor up before and can tell me what works!

Some VGA monitors will sync on green, but its anyone's guess how you find out which one. I would suggest trying other monitors. You might find one that works. 

I think there are various adapters around to do this too, although I don't know what works well, and what does not. 

You could try a capacitor between green and the sync inputs of the VGA. I don't know if its a horizontal sync (pin 13), or a vertical sync (pin 14) that you would go to. I'd be tempted to try 1 nF, if that does not  work try 10 nF, if that does not work try 100 nF, and if that does not work try 1 uF, and perhaps go to 10 uF. I think I would give up at that point if you can't get it to work. I've never done it myself, but I'm pretty sure I have read about people making simple adapters to get the sync pulse out using nothing more than a capacitor.

You could try the HP/Agilent Yahoo group

https://groups.yahoo.com/neo/groups/hp_agilent_equipment/info

There are a *lot* of people there keep old equipment alive. An 8753D is modern by the standards of some equipment people alive there! 

I mate of mine bought an adapter which allows the output from a HP 70000 modular measurement system to be put on a PC. The nice thing about that is that it is possible to capture the image, and so generate reports from it. I don't know if the HP 70000 series uses 3 x BNC, but I suspect it does. I can't easily get around the back of mine to see. But I know his adapter was quite pricy, but he thought it worthwhile the fact he could capture a screen shot and copy/paste to a report for a customer. 

> Thanks

If you don't get any more informative response here, I would certainly try the HP/Agilent Yahoo group, but I'd also be trying other monitors, and sticking a capacitor around to try to get the sync pulse into the monitor. 

Good luck, and if you find a solution, be sure to post it back here. 

Dave

嗨戴夫，再次感谢你的回复。
我找到了一台3571A显示器并将它连接到8753D并在显示器上获得视频;
3571A显示器（如果你知道的话）有一个视频输入（一个RCA插孔）;
看到我不想从其他看台借用测试设备，我试图从互联网上找到一个;
我只能找到一台3571D显示器;
我说，为什么不，它应该工作;
它是在前几天发现的，我发现它上面挂着一根视频线（9针d型公连接器）;
我能够快速购买连接器适配器以适应9针连接器;
我想我需要将引脚＃2（绿色）跳到V-sync（不确定3571D连接器上的哪个引脚）;
在我尝试之前，我应该尝试用帽子跳它;
不是简短，对吗？
不能相信惠普当时使用过不同的视频标准;
笨！
再次感谢！

  Hi Dave, thanks again for you responses. I found a 3571A monitor and hooked it up to the 8753D and got video on the monitor; the 3571A monitor (if you know) has a Video input (one RCA jack); seeing that I am not suppose to borrow test equipment from other stands, I tried to source one from the internet; I was only able to find an 3571D monitor; I said, why not, it should work; it came in the other day and I found a video cable hang out of it (9-pin d-type male connector); I was able to quickly purchase connector adaptors to adapt to the 9-pin connector; I'm thinking that I need to just jump pin#2 (green) to the V-sync (not sure which pin that is on the 3571D connector yet); before I try that, I should try jumping it with a cap; NOT a SHORT, correct?

Can't believe HP used a different video standard back then; stupid!

Thanks again!
John

这不是愚蠢的，它只是预先VGA。
还记得CGA吗？
如果我们将产品延迟几年，那么它将是VGA。

It was not stupid, it was just pre-VGA.  Remember CGA?   Had we delayed the product a few years, then it would have been VGA.

自从我在去年尝试用液晶面板替换8753C CRT后，我想加上我的0.02美元。
我从设备背面的BNC插孔中取出视频。
它具有相同的RGB（绿色同步）和25.5kHz水平同步。
您可以使用GBS-8220街机显示转换板将BNC输出转换为标准VGA，最高可达1024x768（甚至可能高出一步，但我记不得了）。
这块板的价格在30美元左右，你需要供电。
这使您可以驾驶几乎任何现代显示器，但跳过以下段落以达到警告。
我用这个转换器驱动了一个8英寸平板1028x768 LCD面板（带有VGA输入控制器板），经过大量工作后，显示质量非常出色。显示效果实际上比我在单元中安装的全新CRT更好（
最初的索尼OEM Trinitron）。史密斯的图表是圈子，软键也与他们的文本排成一行。我花了几个小时才把GBS-8220放到正确处理视频的位置。它确实变得必不可少
一个同步分离器IC，用于拉出绿色的同步。我想我使用的是LMH1980。显示器也可以很好地正对着现有挡板的后部（形成的CRT“挡板”被移除）。不幸的是，我
完全没时间进一步采取这种方式并且在我的单元中使用新的CRT，并不是真的需要它。因此，为了驱动标准VGA，这块板工作但需要一个带有同步分离器芯片的小PCB（或面包板）
和一些上限。请记住，原来的内部迪的决议
splay与早期的Apple监视器相同。
只是值得深思，不知道驾驶它有多容易。

  Thought I'd add my $0.02 here since I experimented with replacing an 8753C CRT with an LCD panel this past year.  I took video feed from the BNC jacks on the rear of the unit.  This has the same RGB (with green on sync) and 25.5kHz horizontal sync.

You can use a GBS-8220 arcade display converter board to convert the BNC outputs to standard VGA up to 1024x768 (possibly even one step higher res but I can't remember).  This board is in the $30 range and you need to supply power.  This lets you drive almost any modern display but skip the following paragraph to get to the caveat.

I drove an 8" flat panel 1028x768 LCD panel (with VGA input controller board) with this converter and after much work, had display quality that was excellent.  The display presentation was actually better than a brand new CRT I had installed in the unit (the original Sony OEM Trinitron).  Smith charts were circles and the soft keys were lined up with their text also.  It did take me some hours to get the GBS-8220 to where it would handle the video properly.  It did become essential to add a sync separator IC to pull out the sync on green.  I think I used the LMH1980.  The display was also going to sit nicely right up against the rear of the existing bezel (with the formed CRT "bezel" removed).  Unfortunately, I totally ran out of time to take this further and with a new CRT in my unit, didn't really need it.

So, to drive a standard VGA, this board works but needs a small PCB (or breadboard) with a sync separator chip and a few caps.

Keep in mind that the resolution of the original internal display was the same as some early Apple monitors.  Just food for thought, not sure how easy it would be to drive one.

您好，我想尝试一下您的工作。
你在GBS-8220板上使用了什么输入连接器？
问候，迈克

  Hello

I would like to try what you have done.
What input connector did you use on the GBS-8220 board?  

Regards,
Mike
