你好,1)你能帮我选择同轴电子机械开关,频率高达26.5 GHz,带3.5 mm连接器。
在我们的测量中,我们需要在三种不同的测量设置(两个不同的探测站和同轴测量)之间切换PNA-X。 切换仅在寒冷条件下进行。 如果我理解实现这一点的权利,我们需要一个开关驱动器(11713B 24V)和两个四端口开关。 在规格中,我看到“RF输入功率(最大值):平均1瓦特,峰值100瓦”,但没有找到直流电流/电压/功率的最大额定值。 如果我们计划将DC信号偏置到100V并且期望电流高达1A,那么我们的设置是否正确选择购买8767K-024开关? 2)我得到了N5242的报价,我看到以下几行:N5242A-200 N5242AS-H85 N5242AS-285此配置中是否包含前面板接入环路(跳线)? 3)直接连接2.92mm偏置三通直接3.5mm PNA端口是否安全? 谢谢你和最诚挚的问候,Oleg Tokmakov编辑:重新发布于2012年3月15日上午6:16 以上来自于谷歌翻译 以下为原文 Hello, 1) Could you help me to select coaxial electro-mechanical switch for freq up to 26.5 GHz with 3.5 mm connectors. In our measurements we need to switch PNA-X between three different meas setups (two different probe stations and meas in coaxial). Switching will be performed only in the cold condition. If I understand right to implement this we need one switch driver (11713B 24V) and two four port switches. In specifications I saw "RF input power (max): 1 watt average, 100 watts peak" but didn't found maximum ratings for DC current/voltage/power. Is it a right choose to buy 8767K-024 switches for our setup if we planned to bias RF signal with DC up to 100V and expecting currents up to 1A? 2) I got quotation for N5242 where I see following lines: N5242A-200 N5242AS-H85 N5242AS-285 Are front panel access loops (jumpers) included in this configuration? 3) Is it safe to connect 2.92mm bias tees directly 3.5mm PNA ports? Thank you and best regards, Oleg Tokmakov Edited by: reseng on Mar 15, 2012 6:16 AM |

1)不知道,也许一个开关人员会响起2)循环总是包含在所有N524X中3)没问题。
以上来自于谷歌翻译 以下为原文 1) Don't know, maybe a switch guy will chime in 2) Loops always included in all N524X's 3) No problem. |

谢谢! 安捷伦数据采集/开关单元论坛»数据采集 - 一般使用/操作 - 是否适合询问开关人员? 其实我在那里问过,但根本没有重播:-( 以上来自于谷歌翻译 以下为原文 Thank you! Agilent Data Acquisition/Switch Unit Forums » Data Acquisition - General Usage/Operations - is it a right place to ask a switch guy? Actually I asked there but got no replay at all :-( |

我有一个来自我们的TA人员的答案:100 V和1 A没问题。 以下是详细答案:嗨Joel,我收到了如下客户的回复,您可以帮助粘贴到论坛。 我推荐我们的多端口开关87104C(DC-26.5GHz)用于您的应用。 它是一个终止的开关。 以下链接是交换机的详细信息。 http://cp.literature.agilent.com/litweb/pdf/5091-3366E.pdf 11713B能够驱动2个多端口(87104C)交换机。 对于您的问题,切换只在寒冷的条件下进行; 下图(“补充规范(Cold S witching)”)是87104C直通路径的冷开关电源处理,它能够在DC处理您的应用需求100V,1A电流(100W)。 需要注意的是,每条路径的内部50欧姆端接仍限于1W功率处理或+ 7Vdc。 附加信息最大额定功率:1.Into内部终端:1W CW 50W峰值,10us最大脉冲宽度,平均不超过1W 2.通过路径:热切换:2W CW 100W峰值,10us最大脉冲宽度,不超过2W 平均冷切换:参见“补充规范(冷S巫术)”希望这会有所帮助。 谢谢。 最诚挚的问候,Yueh Chin 以上来自于谷歌翻译 以下为原文 I have an answer from our TAO guys on DC: 100 V and 1 A is no problem. Here's the answer in detail: Hi Joel, I have the reply for your customer as below, you could help to paste into the Forum. I would recommend our multiport switch 87104C (DC-26.5GHz) for your application. it is a terminated switch. Below link is the detail of the switch. http://cp.literature.agilent.com/litweb/pdf/5091-3366E.pdf 11713B is able to drive 2 multiport (87104C)switch. For your question, switching will be performed only in the cold condition; below graph (“Supplement Specifications (Cold S witching)”) is cold switching power handling for 87104C thru paths, it is able to handle your application need of 100V with 1A current (100W) at DC. Just noted that, the internal 50ohm termination for each path still limited to 1W power handling or +7Vdc. Additional information Maximum power rating: 1. Into internal termination: 1W CW 50W peak, 10us max pulse width, not to exceed 1W average 2. Into thru path: Hot switching: 2W CW 100W peak, 10us max pulse width, not to exceed 2W average Cold switching: See “Supplement Specifications (Cold S witching)” Hope this will help. Thanks. Best Regards, Yueh Chin |

我们的安捷伦经销商告诉我们,需要N5242-080选项才能使029噪声测量选项正常工作。 这是对的吗? 我们想测量FET噪声。 奥列格 以上来自于谷歌翻译 以下为原文 Our Agilent reseller told us that N5242-080 option is required to get 029 noise meas option working. Is it correct? We want to measure FET noise. Oleg |

对,那是正确的。 如果您查看PNA-X配置指南,您始终可以查看其他选项所需或推荐的选项。 我还将此线程转发给RF交换机团队进行输入。 以上来自于谷歌翻译 以下为原文 Yes that is correct. If you take a look at the PNA-X Configuration Guide, you can always see which options are required or recommended for other options. I have also forwarded this thread to the RF switch team for their input. |
