答案对人有帮助，有参考价值 0 Hi -Question：67 GHz时输出电压的最大变化是多少？答：我会假设您的问题是指E8257D选件567的RF输出，特别是67GHz。我们以dBm而不是电压来指定RF输出变化将取决于所选择的选项.freq = 67Hz标准（dBm）= -20至+ 51EU（dBm）= -20至+ 101E1（dBm）= -110至+ 31EU + 1E1（dBm）= -110至+ 8我们可以将其转换为电压 - 假设阻抗为50欧姆：频率= 67Hz标准（mVrms）= 22.4至397.61EU（mVrms）= 22.4至707.11E1（mVrms）= .0007至315.91EU + 1E1（mVrms）= .0007至561.7问题：为什么需要选件E8257D-1E1？答案：选件1E1是步进衰减器选项，它允许将输出调节到-20dBm以下（50欧姆时为22.4mVrms）。这是需要低电平信号的应用的理想选择。更多信息，请访问：www.agilent.com/find/psgRegards-相关产品：＃E8257D＃以上来自于谷歌翻译以下为原文 Hi - Question: What is the maximum variation of output voltage at 67 GHz? Answer: I will assume that your question refers to the RF output of the E8257D option 567 specifically at 67GHz. We specify the RF output in dBm rather than voltage and the variation will depend on the chosen option. freq = 67Hz Standard (dBm) = -20 to +5 1EU (dBm) = -20 to +10 1E1 (dBm) = -110 to +3 1EU+1E1 (dBm) = -110 to +8 We can convert this to voltage – assuming a 50 ohm impedance: freq = 67Hz Standard (mVrms) =22.4 to 397.6 1EU (mVrms) = 22.4 to 707.1 1E1 (mVrms) = .0007 to 315.9 1EU+1E1 (mVrms) = .0007 to 561.7 Question: Why do you need the option E8257D-1E1? Answer: The option 1E1 is the step attenuator option and it allows for adjusting the output below -20dBm (22.4mVrms at 50 Ohms). This is ideal for applications requiring low level signals.

答案对人有帮助，有参考价值 0 我有一个E8254A PSG信号发生器，它没有1E1选项。我买了衰减器套件并安装好了。该链接不可用于激活衰减器。链接是：http：mktwww.soco.agilent.com/field/service/sources/psg/kits/litlist.htm to activate.Activate Option 1E11。重新连接电源线。打开仪器，让它预热5分钟。激活选项1E1; a。通过以下URL访问PSG（E8200）服务主页：http：mktwww.soco.agilent.com/field/service/sources/psg/kits/litlist.htmb。按照选项1E1升级说明进行操作。验证选项1E1已添加到仪器1中。按Utility>仪器调整>仪器选项>硬件选项。验证选项“1E1”左侧的[x]是否突出显示。是否有解决方法或其他方法来激活衰减器。 sig gen就好像衰减器不在那里一样。我甚至试图用交叉电缆进入E8254A内部服务器。它声明“此功能不可用”，并允许您像软件前面板一样更改发生器设置。我甚至称安捷伦和他们的技术人员说他们不确定它是否可行。任何帮助都会很棒。谢谢以上来自于谷歌翻译以下为原文 I have a E8254A PSG Signal Generator and it didn't have an 1E1 option. I bought the attenuator kit and installed it. The link is not available to activate the attenuator. The link is: http:mktwww.soco.agilent.com/field/service/sources/psg/kits/litlist.htm to activate. Activate Option 1E1 1. Reconnect the power cord. 2. Turn the instrument on and let it warm up for 5 minutes. 3. To activate Option 1E1; a. go to the PSG (E8200) service home page at the following URL: http:mktwww.soco.agilent.com/field/service/sources/psg/kits/litlist.htm b. Follow the Option 1E1 upgrade instructions. Verify that Option 1E1 has been added to the instrument 1. Press Utility > Instrument Adjustments > Instrument Options > Hardware Options. 2. Verify that the [x] on the left side of option “1E1” is highlighted. Is there a work-around or some other way to activate the attenuator. The sig gen works as if the attenuator is not even there. I even tried to get into the E8254A internal server with a crossover cable. It states "this feature is not available" and allows you to change the generator settings like a software front panel. I even called Agilent and their techs said they are not sure it is possible. Any help would be great. thanks
