回读电流限制

嗨凯文，我可以在这里帮助你。
N6700电源的过流保护与过压保护略有不同。
过压保护（OVP）具有您设置的限制。
当电源超过该限制时，设备将关闭。
过流保护（OCP）的不同之处在于您没有设置硬限制。
当电源从恒定电压（CV）模式过渡到恒定电流（CC）模式时，OCP启动，这种模式在达到编程的电流限制时发生。
如果要查看当前限制的设置，可以发送命令CURR？
（@ 1）。
OCP也与OVP不同，因为您可以启用和禁用它。
您可以通过发送CURR来检查OCP的状态：PROT：STAT？
（@ 1）。如果这回答了你的问题，或者你想更多地讨论这个问题，请告诉我。马特

  Hi Kevin,

I can help you here.  Over current protection on the N6700 supplies works a little bit different from the over-voltage protection.  Over voltage protection (OVP) has a limit that you set.  When the power supply exceeds that limit, the unit shuts down.  Over-current protection (OCP) is different in that you do not set a hard limit.  OCP engages when the power supply crosses from Constant Voltage (CV) mode to constant current (CC) mode which happens when the programmed current limit is reached.  If you want to see what the current limit is set to, you can send the command CURR? (@1).  OCP is also different than OVP in that you can enable and disable it.  You can check the status of OCP by sending CURR:PROT:STAT? (@1).

Please let me know if this answers your question or if you would like to discuss this more.

Matt

嗨凯文，没有愚蠢的问题！
相信我，当我第一次开始研究电源时，我根本不知道这些东西！CURR命令设置电流限制。
如果DUT需要超过设定的电流限制（这由欧姆定律决定），电源将进入电流限制。
我们的暑期实习生Teddy整理了两个视频，解释了CV / CC模式的工作原理。
以下是视频的链接：第1部分 - > http://youtu.be/AsBx52mWzwMPart 2 - > http://youtu.be/RYz1L6zgqNETo获取实际电压和电流测量值，需要发送以下两个命令：
MEAS：VOLT？
（@ 1）MEAS：CURR？
（@ 1）这些命令将熄灭并直接测量输出电压和电流。如果您有任何其他问题，请告诉我。

  Hi Kevin,

There are no dumb questions!  Believe me when I first started working on power supplies, I had no idea about any of this stuff!

The CURR command sets the current limit.  The supply will go into current limit if the DUT requires more than the set current limit (this is decided by Ohm's Law).  Our summer intern Teddy put together two videos explaining how CV/CC modes work.  Here are the links to the videos:

Part 1 -> http://youtu.be/AsBx52mWzwM
Part 2 -> http://youtu.be/RYz1L6zgqNE

To get the actual voltage and current measurements, you need to send the following two commands:
MEAS:VOLT? (@1)
MEAS:CURR? (@1)

These commands will go out and directly measure the output voltage and current.

Let me know if you have any other questions.

谢谢！
