您好,我的A7板显然有问题。
我已经存放了我的分析仪1年,等待以合理的价格找到A7板,最后我找到了一个& 现在我无法运行频率校准。 我改变了新的A7,运行cal freq& 我每次都有:CAL:主线圈感应失败CAL:零失败CAL:跨度感觉失败因此我认为它有问题但是我更换了旧的线圈感应器。 我有同样的问题,上次我测试它CAL freq正在工作。 更换A7板或我的分析仪的其他部分已经死亡时,是否有任何程序要遵循? 谢谢。 以上来自于谷歌翻译 以下为原文 Hello, my A7 board was apparently faulty. I have stored my analyzer for 1 year waiting to find a A7 board for a good price, finally I find one & now I can't run the freq cal. I changed the A7 for the new one, run cal freq & every time I have: CAL: Main coil sense fail CAL: Zero fail CAL: Span sens fail So I thought it was faulty but I replaced the board for the old one & I have the same problem, last time I tested it CAL freq was working. Is there any procedure to follow when changing A7 board or other part of my analyzer has died? Thank you. |

uvysdfydad 发表于 2018-11-5 12:48 谢谢你回答,我不能运行cal freq所以...我怀疑A3A7 YTO可能有问题,不确定。 以上来自于谷歌翻译 以下为原文 Thank you for answering, I can't run cal freq so... I suspect the A3A7 YTO maybe is faulty, not sure. |

你能看到任何校准信号吗? 我猜你用手册中描述的-37 Hz密码尝试了cal这些错误? 您是否有另一台分析仪来查看YTO的输出? 如何检查YTO的J3电压,包括通过主线圈的电流? 我同意这听起来不太有希望。 以上来自于谷歌翻译 以下为原文 Can you see any cal signal at all? I guess you tried the cal with the -37 Hz passcode as described in the manual for these errors? Do you have another analyzer to look at the output of the YTO? How about checking voltages coming out of J3 at the YTO, including current through the main coil? I agree it doesn't sound too hopeful. |

你好......屏幕上没有信号,我用接收机测试了 我有300 MHz的输出,尾纤是可以的,所以有输入信号尝试-37& -2001没有结果我没有任何其他分析仪,我只是一个业余爱好者我找到了关于引脚功能和信息的信息。 在这个论坛中A3A7的线圈值,我必须找到它的方法(它在分析仪的中间)但我只能测试伏特,阻抗..我想我也可以测试VSWR但不多。 请问看看他的A7主板输出? 到A3A7谢谢MarkL 以上来自于谷歌翻译 以下为原文 Hello... There is no signal on screen, I tested with a receiver & I have output at 300 MHz, pigtail is OK so there is input signal Tried the -37 & -2001 with no results I don't have any other analyzer, I'm just an amateur I found the information about pins functions & values for coils for the A3A7 in this forum, I must find the way to reach it (It is in the middle of the analyzer) but I just can test volts, impedance.. I think I can test also VSWR but not much more. Will take a look at he A7 board output? to the A3A7 Thank you MarkL |
