嗨......我是这个论坛的新手。我已经安装了带有HP8481A热电偶(-30到+20 dBm)传感器的Agilent 437B,我打算买一个二极管传感器。
我的第一选择是HP 8481D,但我刚刚发现HP 8484A二极管传感器的功能基本相同(-70到-20 dBm,10 MHz-18 GHz,与43x米兼容......)然而, 显着差异:价格! 8481D几乎是8484A的两倍!有人能告诉我两者之间的主要区别吗? 我已经在网上搜索了8484A和8481D手册没有成功。谢谢你的关注! 以上来自于谷歌翻译 以下为原文 Hi... I'm new on this forum. I already have an Agilent 437B with a HP8481A thermocouple (-30 to +20 dBm) sensor and i plan to buy a diode sensor. My first choice was the HP 8481D but i just discovered that the HP 8484A diode sensor does essentially the same thing (-70 to -20 dBm, 10 MHz-18 GHz, compatible with the 43x meters...) with, however, a significant difference: Price ! The 8481D is almost twice as expensive as the 8484A ! Can someone tell me the main difference between the two ? I've made search on the Net to get the 8484A and 8481D manuals w/o success. Thanks for your attention ! |

谢谢...但是除了它的过时,8484A和8481D之间还有其他区别吗?
正如我所写,我找不到8484A和8481D的详细规格来比较两个传感器。它们都是二极管传感器,工作频率高达18 GHz,电平范围从-70 dBm到-20 dBm并且与 43x系列米。 (我有一个437B) 以上来自于谷歌翻译 以下为原文 Thank you... But outside of it's obsolescence, are there other differences between the 8484A and 8481D ? As i wrote, i couldn't find the detailed specs of the 8484A and 8481D to compare both sensors. They are both diode sensors, work up to 18 GHz, and have level ranges from -70 dBm to -20 dBm and compatible with the 43x series meters. (i have a 437B) |
