在确定我的E4436B的锁相丢失是由于FRAC-N板上的1GC1-4210 SSOP芯片有缺陷之后，我现在正在寻找替代芯片。
安捷伦仍然存放这种芯片吗？ 如果是这样，我是否可以从安捷伦购买芯片，或者我是否必须将我的电路板送到安捷伦让他们更换芯片？如果安捷伦不再购买芯片，有没有人知道他们的可靠来源？ ？ 我一直与一些芯片供应商（他们似乎都在中国）有过接触，但我担心有可能获得可用的，符合规格的芯片，因为我不熟悉这些公司和 因此没有依据可以选择任何一个供应商而不是其他任何一个供应商。斯坦 以上来自于谷歌翻译 以下为原文 After determining that the loss of phase lock of my E4436B is due to a defective 1GC1-4210 SSOP chip on the FRAC-N board, I am now looking for a replacement chip. Does Agilent still stock this chip? If so, is it possible for me to purchase just the chip from Agilent, or do I have to send my board into Agilent to have them replace the chip? If Agilent no longer stocks this chip, does anyone know of a reliable source for them? I have been in contact with a number of chip suppliers (all of whom seem to be in China), but am concerned about the likelihood of getting a usable, in-spec chip, given that I have no familiarity with any of these companies and therefore have no basis upon which to pick any one supplier over any other. Regards, Stan

我们还有一块带有失败的1GC1-4210Is的分数N板仍然可以获得该部件？该板不再可用且仪器不支持。
E4423B我们需要做什么来购买1pc或2分频器？或者如果它不再可用，是否有任何引脚图，因为有一些分频器可能有效....但是没有关于是否有信息的信息 该部分是串行或并行编程的。谢谢。 以上来自于谷歌翻译 以下为原文 We also have a fractional N board with a failed 1GC1-4210 Is is still possible to get the part? The board is no longer available and the instrument is out of support. E4423B What do we have to do to buy 1pc or 2 of the divider? Or if it is no longer available, is there any pinout diagram because there are a few frequency dividers that could potentially work.... But there is no information about whether the part is programmed serially or parallel. Thank you. |

可悲的是，我的E4437B似乎遭遇了Frac-N板上分频器芯片的故障。
这种情况下的错误是YIG解锁，输出似乎是带限噪声（在查看方框图后看起来很合理）。 注意：安装的部件是安捷伦部件 - 但是电路板是E4423-60019而不是E4423-69019所以 - 是否有任何地方可以容纳其中一个设备（1GC1-4210）范围内的任何一个频段都不会导致 锁定 - 所以我怀疑1GC1-4210完全失效，或者至少第一阶段除以2.我将尝试确认Frac-N板的500-1000Mhz输出是否良好，如果是这种情况我认为 我可以肯定吗？ 任何建议很乐意。 以上来自于谷歌翻译 以下为原文 Sadly it appears that my E4437B has suffered from failure of the divider chip on the Frac-N board. The error in this case is a YIG unlock , and the output appears to be band limited noise ( which looks sensible after reviewing the block diagrams ). Note: the part fitted is an Agilent part - but the board is an E4423-60019 not E4423-69019 So - is there anywhere to get hold of one of these devices ( 1GC1-4210 ) None of the bands in the range result in a lock - so I suspect total failure of the 1GC1-4210 , or at least the firs stage divide by 2. I shall attempt to confirm all is well with the 500-1000Mhz output from the Frac-N board , if that's the case I think I can be certain ? Any advice gladly taken. |

vtqtweqwe 发表于 2019-5-8 17:29 好的，所以我检查了500-1000Mhz进样板 - 看起来不错。 还检查了1Ghz进入样本 - 再次看起来没问题。 所以 - 我想下一步是检查YIG驱动器输出，不幸的是我没有能力的4-8Ghz范围。 我应该从YIG驱动程序中得到什么样的信号？ 光谱纯净？ 我想我可以将1Ghz从我的另一个sig gen输入到frac-n分频器链中，看看我在输出中得到了什么。 以上来自于谷歌翻译 以下为原文 Okay so I checked the 500-1000Mhz into the sample board - that looks good. Also checked the 1Ghz into the sample - again looks okay. So - I guess the next thing is to check the YIG driver output , unfortunately I have nothing capable of the 4-8Ghz range. What sort of signal should I expect from the YIG driver ? Spectrally pure ? I guess I could feed 1Ghz from my other sig gen into the frac-n divider chain and see what I get at the output. |

vtqtweqwe 发表于 2019-5-8 17:36 好吧 - 毕竟它可能不是分频器（phew）。 我可以使用频率分析仪，其频率高达4.3Ghz，并且没有看到YIG的任何输出。 为了尝试确认这一点，我将1Ghz + 6dbM注入frac-n分频器。 RF输出现在看起来要好得多，频率峰值而不是宽频谱噪声。 （本底噪声下降而不是大约-50dbM）所以看起来越来越像YIG / Driver问题。 YTO预调整可能有帮助吗？ 或者它看起来像YIG或驱动程序中的实际故障？ 再次 - 这个完全死亡的论坛的建议表示赞赏。 以上来自于谷歌翻译 以下为原文 Okay - well it might not be the divider after all (phew). I have access to a spectrum analyser which goes upto 4.3Ghz , and didn't see any output from the YIG. To try and confirm this I injected 1Ghz +6dbM into the frac-n divider. The RF output now looks a lot better , frequency peaks rather than wide spectrum noise. ( noise floor drops right down rather than being around -50dbM ) So looks more and more like a YIG/Driver problem. Is it possible that a YTO pretune adjustment might help ? Or is it looking like an actual fault in either the YIG or the driver ? Again - advice from this totally dead forum appreciated. |

YTO / YIG的M +端子似乎卡在-15V。
听起来像预习问题？ 电流源/ DAC /校准？ 这个YTO有永久磁铁吗？ 或者共振是否完全取决于通过主线圈和FM线圈的电流？ （对不起，这是我第一次使用YIG相关项目）所以 - 我已经下载了校准软件 - 并订购了一个GPIB接口。 以上来自于谷歌翻译 以下为原文 The M+ terminal of the YTO/YIG seems stuck at -15V. So sound like a pretune problem ? Current source /DAC / Calibration? Does this YTO have a permanent magnet ? Or is the resonance purely dependant on the current through the main and fm coils ? ( sorry this is my first time with YIG related items ) So - I've downloaded the calibration software - and ordered a GPIB interface. |

好吧 - 我通过Falcon软件做了一些进一步的测试 - 它确实似乎证实了预调节DAC有问题。
设置预调节DAC对yto preune的abus读数没有影响（总是在-0.018伏左右。（即使DAC设置为4095也是相同的）所以要么是dac故障，要么是abus监控点之前的一个运算放大器 哦，我希望我有一个yto驱动板的原理图。 以上来自于谷歌翻译 以下为原文 Well - I did some further tests via the Falcon software - and it does seem to confirm that the pre-tune DAC has a problem. Setting the pretune DAC has no effect on the yto pretune abus reading ( always sits around -0.018 volts. ( even a DAC setting of 4095 is the same ) So either a dac failure or one of the op-amps prior to the abus monitoring point. Oh how I wish I had a schematic for the yto driver board. |

多一点进步。
dac看起来没问题 - 而且它之后的运算放大器似乎没问题（因为当从4ghz调到2ghz时，op27的输出从-4v到-2v很好地变化，然后在2ghz以下回到-4v）此后信号进入 AD797运算放大器 - 但该运算放大器的输出似乎停留在-13.7v。 该运算放大器的输出似乎驱动了摩托罗拉23p06 fet的栅极，该栅极控制在yto中流动的电流。 所以故障是AD797或它周围的无源器件。 据推测，ad797和23p06形成电压到电流转换器。 任何人都有这部分的原理图？ 以上来自于谷歌翻译 以下为原文 A little more progress. The dac seems okay - and the opamp after it seems okay ( because the output of the op27 varies nicely from -4v to -2v when tuning from 4ghz to 2ghz , then back to -4v at just under 2ghz ) After this the signal enters an AD797 opamp - but the output of this opamp seems stuck at -13.7v. The output of this opamp appears to drive the gate of a motorola 23p06 fet which controls the current flowing in the yto. So the fault is either the AD797 or passives around it. Presumably the ad797 and 23p06 form a voltage to current convertor. ANYONE have a schematic of this section? |

好的 - 有点好消息 - 我勾勒出当前司机的原理图 - 我得出的结论是它必须是司机胎。
所以 - 当我注意到它没有安全焊接时，我只是看着拆焊它:-)，重新焊接胎儿，现在我有信号输出！ yto仍未锁定 - 但我们正在进步。 （猎鹰软件yto驱动程序测试全部通过）。 以上来自于谷歌翻译 以下为原文 Okay - somewhat better news - I sketched the schematic for the current driver - and I had come to the conclusion that it had to be the driver fet. So - I was just looking at desoldering it when I noticed that it wasn't securely soldered :-) , resoldering the fet and now I have signal output !. The yto is still not locked - but we're progressing. ( the falcon software yto driver tests all pass ). |
