由于没有专门用于与功率计通信的论坛，我将这些问题放在这里，看看会发生什么。
我想知道更多关于与E4419B功率计“说话”的两件事。 请记住，我现在不可能使用HPIB.1）如何通过RS-232与E4419B进行通信？ 我是否需要使用零调制解调器电缆进行通话？ 是否有任何类型的程序可以对前面板进行数据记录？2）我的E4419B功率计上的记录器输出似乎根本不起作用。 从前面板菜单中，我为Ch A打开了录音机输出，我将最大功率设置为100 W（最小功率0W），我只是将信号发生器用于Ch A，看看录音机输出是否正常工作 。 我的功率计有一个偏移，因此1mW看起来像100W。 我根本没有输出电压。 也许其他人有这个问题并且知道如何解决它？如果我不能通过RS-232说话，我希望能够使用记录器输出和数据记录至少输出电压。 我更喜欢RS-232，但只要我能从任何一个登录，我会很高兴。 有人可以提供帮助吗？ dennis *功率计几周前刚刚进行了校准，看起来效果很好。 以上来自于谷歌翻译 以下为原文 Since there was no forum specifically for communicating with power meters, I am putting these questions here and see what happens. I have two things that I would like to know more about concerning "talking" with a E4419B power meter. Keep in mind that using HPIB is not a possibility right now for me. 1) How do you communicate via RS-232 to the E4419B? Do I need a null modem cable to talk? Is there any kind of program available that will allow datalogging of the front panel? 2) The recorder outputs do not seem to work at all on my E4419B power meter. From the front panel menu, I have the recorder output turned on for Ch A, I have the max power set to 100 W (min power 0W) and I am just using a signal generator into Ch A to see if the recorder output even works. I have an offset in the power meter so that 1mW looks like 100W. I get no output voltage at all. Maybe somebody else has had this problem and knows how to fix it? If I cannot talk through RS-232, I would like to be able to use the recorder output and datalog the output voltage at least. I would prefer RS-232 but as long as I can log from either one, I would be happy. Can anybody provide help? dennis * Power meter just went though a calibration a couple weeks ago and otherwise seems to work fine.

你好丹尼斯，根据EPM编程手册，它有一个DTE串行连接器，所以你需要一个零调制解调器电缆与PC通信。至于拉回数据，你应该能够使用Intuilink EPM来记录数据
直接到Excel。 以下是用于RS232通信的Intuilink EPM FAQ文件的推荐电缆。 您还需要安装Agilent IO Libraries才能使用此工具。我尝试使用USB转串口适配器和带有E4418B的旧Agilent 24542U串行零调制解调器电缆并且工作正常，尽管使用RS232的通信比GPIB慢得多 。 我设置了10次测量的记录，间隔为1秒，每次测量大约需要5秒。 您需要在IO配置的COM配置和功率计的COM配置（系统/输入 - >远程接口 - >配置接口 - >串行 - >更多1 / 2->起搏）中设置流量控制 DTR / DSR。“-----------------> -----------------我应该使用什么接口电缆用于RS-232 （COM）通信？解答：以下内容已通过本产品的RS-232通信测试：o电缆部件号RS232-61601注意：将工具栏上的流量控制（握手）模式和仪器设置为DTR以进行RS-232通信。 “至于录像机输出，您是否确认它们已在固件中启用（系统/输入 - >更多1 / 2->录像机输出）？ 以上来自于谷歌翻译 以下为原文 Hello Dennis, According to the EPM Programming Manual, it has a DTE serial connector, so you will need a null-modem cable to communicate with the PC. As for pulling data back, you should be able to use Intuilink EPM to log the data directly to Excel. Below is the recommended cable from the Intuilink EPM FAQ file for RS232 communication. You will also need the Agilent IO Libraries installed to use this tool. I tried this with a USB to Serial adapter and an old Agilent 24542U serial null modem cable with an E4418B and it worked fine, although the communication was much slower using RS232 than GPIB. I setup a log of 10 measurements with a 1 second interval and it took about 5 seconds per measurement. You will need to set the Flow Control in the COM configuration for the IO libs and the COM configuration of the power meter (System/Inputs->Remote Interface->Configure Interface->Serial->More 1/2->Pacing) to DTR/DSR. " As for the recorder output, have you verified that they are enabled in the firmware (System/Inputs->More 1/2->Recorder Output)? |

O.J.，感谢Intuilink S / W的链接。
这是我没有的东西。 我相信我的计算机上安装了I / O库。 感谢配置中的帮助。 我将不得不想出一个零调制解调器电缆。关于录音机输出：我确实已经为两个声道打开了录音机输出，即使我只使用Ch A.我以为我会列出关于电源的固件信息 仪表，只是让你知道我在这方面的位置。仪表：E4419BMain F / W Rev：A2.07.00主要F / W日期：2000年5月16日10：03Bootrom Rev：A.02.00Proc。 BD。 版本：CSystem版本：2DSP修订：A.01.11（Ch A）A.01.11（Ch B）门阵列版本：A.01.03（Ch A）A.01.03（Ch B）我只在记录仪上测量0.2mV的值 输出，无论我设置最大/最小功率配置按钮。 我相当于960W（即使实际输入功率仅为0dBm，仪表表示正在测量），最大功率配置按钮设置为1kW，最小功率为10W，记录器输出为0.2mV。 这就是我的世界里正在发生的事情 以上来自于谷歌翻译 以下为原文 O.J., Thanks for the link for the Intuilink S/W. That was something that I did not have. I believe that I do have the I/O libraries installed on my computer. Thanks for the help in the config too. I will have to come up with a null modem cable. About the recorder output: I do have the recorder outputs turned on for both channels, even though I am only using Ch A. I thought that I would list the firmware info about the power meter, just so you know where I am at in that respect. Meter: E4419B Main F/W Rev: A2.07.00 Main F/W Date: May 16, 2000 10:03 Bootrom Rev: A.02.00 Proc. Bd. Version: C System Version: 2 DSP Revision: A.01.11 (Ch A) A.01.11 (Ch B) Gate Array Rev: A.01.03 (Ch A) A.01.03 (Ch B) I only measure something like 0.2mV on the recorder output, no matter what I set the Max/Min power config buttons to. I have the equivalent of 960W (what the meter says it is measuring even though the real input power is only 0dBm), Max power config button is set to 1kW, Min Power is 10W, and the recorder output is 0.2mV. That is what is going on in my world. dennis |

您好Dennis，我会假设您使用显示器或通道偏移来使仪表读取960W（类似于59.8 dB的偏移值）。
这将是有问题的，因为根据手册，这些偏移对记录器输出没有影响。 尝试使用下面的值，看看它们是否能提高读数，因为它们是功率传感器实际测量的功率。最小功率：-20 dBm（10 uW）最大功率：0 dBm（1 mW） 以上来自于谷歌翻译 以下为原文 Hello Dennis, I would assume that you are using a display or channel offset to get the meter to read 960W (something like a 59.8 dB offset value). This would be problematic because these offsets have no effect on the recorder output according to the manual. Try using the values below and see if they improve your readings since they are the powers the power sensor is actually measuring. Min Power: -20 dBm (10 uW) Max Power: 0 dBm (1 mW) |

我确实从功率计中删除了任何偏移量，录音机输出现在可以正常工作。
从来没有这样的情况，因为我做了（做BTW从来不是一件好事），当你在前面板上设置最小/最大功率时，重新编码输出会自动缩放。 我们在这里生产高功率射频产品，在高达10kW +的功率水平下进行测试并不罕见。 仍在致力于让RS-232继续运行。 在我的笔记本电脑上刻录CD刻录时遇到了问题。 我需要直接下载Intuilink程序。 此致，丹尼斯 以上来自于谷歌翻译 以下为原文 I did remove any offsets from the power meter and the recorder output now works as it should. Never would have though that was the case because I asssumed (which is never a good thing to do BTW) that when you set your min/max power on the front panel, then the recoder output would scale automatically. We make high power RF products here and it is not unusual to test at power levels of up to 10kW+. Still working on getting RS-232 going. Been having problems with burned CD's reading on my laptop that does all my measurments. I will need to download the Intuilink program directly. Regards, dennis |
