正如在我上一篇文章中我试图找出一大批未知的freq mobile＆amp;便携式天线。我一直试图找到他们设计的频段，使用8720分析仪设置为S11返回损耗，然后切换到史密斯图表检查50欧姆。问题是它们没有接近我认为应该是的频率，即使是已知的工厂天线也应该更高或更低。我错过了什么吗？以上来自于谷歌翻译 以下为原文 As in my previous post i am trying to identify a big batch of unknown freq mobile & portable antennas.I have been trying to find the bands they were designed for by using 8720 analyzer set to S11 return loss and then switch to smith chart to check for 50 ohms. Problem is that they are not coming up close to the frequency i think they should be, even a known factory antenna also comes up eitherhigher or lower that it should be.Am i missing something here?

我使用ST L6470和单极电机。 L6470是双极型驱动器，所以我没有连接单极电机的com线。 电机规格如下： MAKER：sanyo denki 型号：103H5210-0480 1.2A / 1.8DEGREE / 3.3OHM。 因为未连接的com线路，电阻器为6.6Ohm。 我在电机中应用DC24V。 问题是电机没达到1500PPS。在1000PPS以下，电机运行良好。 是单极电机不是双极的问题吗？ 我改变了所有变量因子（acc，dec，kval等等），但它达到了1500PPS。 哪里不对？ #D 以上来自于谷歌翻译 以下为原文 I use ST L6470 with unipolar motor. L6470 is biplar type dirver, so I unconnected com line of unipolar motor. motor spec is below: MAKER: sanyo denki type : 103H5210-0480 1.2A/1.8DEGREE/3.3OHM. because unconnected com line, resistor is 6.6Ohm. I apply DC24V in the motor. The problemis that motor is not reached 1500PPS.under 1000PPS, motor is well opeared. Is it problem thar unipolar motor is used not bipolar? I changed all variable factor(acc,dec,kval, etc...), but it reached 1500PPS. what is wrong? #d
