在我的DSOX 3014A上,我发现1mV / div输入灵敏度为低。
因此,我正在寻找一种可以直接放在BNC输入连接器上的放大器,它可以从下面的连接器获得电源。 目前放大10倍就足够了。 但如果它有100倍的放大率,这也可能有用。 或者是否可以购买一些带有DSOX 3000接口引脚的空通用BNC盒? 然后我可以自己构建放大器。 谁知道输入端口下的9个焊盘用于什么? (似乎有一个......)这里有什么电压? 他们有多干净和稳定? 最好的问候,/Sören 以上来自于谷歌翻译 以下为原文 On my DSOX 3014A I find the 1mV/div input sensitivity to low. Therefor I'm looking for an amplifier that can be placed directly on the BNC input connector and that can get power supply from the connector underneath. 10 times amplification is enough for the moment. But if it has 100 times amplification this may also be useful. Or is it possible to purchase some empty general purpose BNC-box with DSOX 3000 interface pins? Then I can build the amplifier myself. Anyone who knows what the 9 pads under the input ports are used for? (One seems to be ground...) What voltages are available here? How clean and stable are they? Best regards, /Sören |

9pin Autoprobe的一些信息:1:+3伏2:-3伏3:偏移(这是由示波器中的dac驱动)在+3和-3之间连接一个2k2微调。
擦拭器通过一个1k电阻连接到该引脚4:SDA(示波器使用它来读取校准数据)5:环(这是探测器ID,它告诉示波器附加了什么。你没有连接它。 浮点数)6:SCL(示波器使用它来读取校准数据)7:Rp:这告诉示波器该探测终止应该是什么:你将它保持浮动状态。 探头需要50欧姆端接,你的分析仪就有这个。 8:-12伏9:+ 12伏这里你可以找到更多信息:http://www.eevblog.com/forum/buysellwanted/active-probe/我正在制作一个适配器,用于在Agilent Oscilloscpoe上使用我目前的探头。 以上来自于谷歌翻译 以下为原文 Some information of of 9pin Autoprobe: 1 : +3 volts 2 : -3 volts 3 : offset ( this is driven by a dac in the scope ) connect a 2k2 trimmer between +3 and -3. the wiper goes via a 1k resistor to this pin 4 : SDA ( this is used by the scope to read the calibration data ) 5 : Ring ( this is the probe ID that tells the scope what is attached. you do not connect this. leave floating ) 6 : SCL ( this is used by the scope to read calibration data ) 7 : Rp : this tells the scope what the termination should be for this probe : you leave this floating. The probe needs 50 ohm termination and your analyzer has this. 8 : -12 volts 9 : + 12 volts Here you can find more info: http://www.eevblog.com/forum/buysellwanted/active-probe/ I am making an adapter to use my current probe on Agilent Oscilloscpoe. |

xixunled 发表于 2019-4-18 19:52 我有同样的问题,但我需要一种方法来将1mv麦克风级别提升到我的DSOX3024上可测量的水平。 它不必是DC耦合的。 我正在尝试一种RIAA放大器模块,我从汽车音响中取出。 我用平坦的响应修改它并将增益改为100X。 它有效,但我需要一种更好的方法来校准增益。 两个9v电池提供干净的直流电源,但我宁愿使用LDO稳压电源。编辑:Willco788于2013年4月1日下午7:54 以上来自于谷歌翻译 以下为原文 I had the same problem but I needed a way to boost a 1mv microphone level to something that measureable on my DSOX3024. It doesn't have to be DC coupled. I'm experimenting with a an RIAA amplifier module that I pulled from a car stereo. I modified it with a flat response and changed the gain to 100X. It works but I need a better way to calibrate the gain. Two 9v batteries provide a clean DC supply but I would rather use an LDO regulated power supply. Edited by: Willco788 on Apr 1, 2013 7:54 PM |
