我最近从废料箱中取出了一个拆卸的8487A,墨盒被烧坏了,波纹管和匹配的垫圈都丢失了,我从Q8486A拿了墨盒,然后在配套的洗衣机上订购了风箱,而不是
确定哪一个使用,因为备件列表在匹配的垫圈上调出四个不同的部分#,我把它放在一起它工作正常,大约30GHz,30GHz以上的功率读数约为3dB低,这可能是由于 缺少配套垫圈? 我该如何确定使用哪种洗衣机? 我在其中一个VNA工作时测量了VSWR并且它不符合30GHz以上的规格,所以我认为损失与不匹配有关,我没有将发送传感器送出维修,Q8486A墨盒和 8487A cartride似乎大小相同 以上来自于谷歌翻译 以下为原文 I recently pulled a disassembled 8487A from the scrap bin, the cartridge turned out to be blown and the bellows as well as the matching washer was missing, i took the cartridge from a Q8486A and ordered the bellows from agilent, on the matching washer im not sure which one to use since the spare parts list calls out four different part# on the matching washer, i put the unit together and it works ok up to about 30GHz , above 30GHz the power reads about 3dB low, can this be due to the missing matching washer ? how do i determine which washer to use ? i measured the VSWR on one of the VNA s at work and it doesnt meet spec above 30GHz as well so i think the loss is mismatch related, i dont have the $$$ to send the sensor out for repair, the Q8486A Cartridge and the 8487A cartride seem to be identical in size |

在标量探测器和桥接器中,在组装时选择匹配垫圈以提供部件的适当匹配或销钉深度。
因此,装配工将测量其他零件并选择提供适当尺寸的垫圈。 以上来自于谷歌翻译 以下为原文 In the scalar detectors and the bridges, the matching washers were selected at time of assembly to provide the proper match or pin depth of the part. So, the assemblers would measure the other parts and choose the washers which provided the proper dimensions. |
