嗨，我尝试使用KE5FX工具包和Prologix GPIB-USB卡捕获屏幕。
它们适用于频谱显示，但是当SA设置为零跨度以显示时域波形时，我可以捕获的所有内容都是带有刻度和标记的空屏幕，但没有迹线。 我想知道信号是否在零跨度下没有数字化？ 谢谢。 以上来自于谷歌翻译 以下为原文 Hi, I tried to capture the screen with KE5FX toolkit and with a Prologix GPIB-USB card. They work fine for spectrum displays, but when the SA is set to zero-span to display time-domain waveform, all I can capture is an empty screen with graticule and markings, but no trace. I was wondering if the signal is not digitized under zero-span? Thanks.

我首先要确认8560E正在HPGL流中发送零跨度跟踪。
使用KE5FX获取并保存.PLT文件中的HPGL命令，然后在文本编辑器中查看.PLT文件。 HPGL是ASCII，很明显哪个HPGL命令正在执行实际的跟踪图。 它应该以“PA”开头，然后是一长串X，Y坐标，它指示笔应该如何移动以形成轨迹。 如果该行看起来像在绘图文件中，请尝试使用其他HPGL查看器。 如果不是，请使用KE5FX中的一些低级GPIB实用程序，如PARSE，TALK，LISTEN，QUERY，以进一步查看8560E响应绘图命令发送的内容。 以上来自于谷歌翻译 以下为原文 I would start by confirming that the 8560E is sending the zero-span trace in the HPGL stream. Use KE5FX to acquire and save the HPGL commands in a .PLT file and then look at the .PLT file in a text editor. HPGL is ASCII and it should be obvious which HPGL command is doing the actual trace plot. It should start with "PA", followed by a long string of X,Y coordinates which dictate how the pen should move to make the trace. If the line looks like it's in the plot file, try a different HPGL viewer. If it's not, use some of the low level GPIB utilities in KE5FX like PARSE, TALK, LISTEN, QUERY, to further see what the 8560E is sending in response to a plot command. |

如果仪器没有选项007（数字化快速时域扫描），这很可能是问题，因为迹线未被数字化。
当您在屏幕上显示跟踪时，您是否可以使用其上的标记？ 如果不是这就是你的问题。 最好的问候，迈克 以上来自于谷歌翻译 以下为原文 If the instrument does not have option 007 (Digitized Fast Time Domain Sweeps) this is most likely the issue since the trace is not digitized. When you have the trace on the screen are you able to use the markers on it? If not this is your issue. Best regards, Mike |

附件是选件007升级套件仍可用时使用的安装说明。 它包含有关如何安装选件以及所需部件列表的说明。 我注意到你必须有一个支持这个选项的A3接口板组件。 从我所看到的，如果仪器是串行前缀3517A或更新，现有的A3应该没问题。 您还需要通过远程控制启用该选项。 安装说明引用了一个程序来执行此操作，可以在以下几种不同的表单中找到：http：//www.keysight.com/find/8560_software最好的问候，迈克 以上来自于谷歌翻译 以下为原文 Attached is the installation note that was used when an option 007 upgrade kit was still available. It has the instructions on how to install the option along with a list of required parts. I notice in it you must also have an A3 Interface board assembly that supports this option. From what I can see if the instrument is serial prefix 3517A or newer the existing A3 should be fine. You also need to enable the option via remote control. The installation note references a program to do so, which can be found in a few different forms at: http://www.keysight.com/find/8560_software Best regards, Mike 附件

cmh23 发表于 2018-11-1 13:29 非常感谢，迈克。 你真的很有帮助！ BTW，关于8560E系列中使用的YTO，据说它们在正常使用期间容易出现故障。 您对此问题有任何见解吗？ 再次感谢你的帮助。 以上来自于谷歌翻译 以下为原文 Thank you so much, Mike. You've been really helpful! BTW, regarding the YTOs used in 8560E series, it is said that they are prone to failure during normal use. Do you have any insights to this issue? Thanks again for your help. |

与任何其他电子组件一样，8560系列中的YTO有时会出现故障并需要更换，但其故障率始终完全符合我们的可靠性目标...... Mike 以上来自于谷歌翻译 以下为原文 Like any other electronic assembly the YTO in the 8560 series does fail at times and needs to be replaced, but its failure rate has always been well within our goal for reliability... Mike |
