7V以上的偏置是否会对E5061B-3LF端口造成损坏?

我们的E5061B-3LF带有直流偏置电源选项,直流输出范围为-40V至40V。
该DC输出可以连接到单独的输出或连接到端口1,端口1的最大允许直流电压为7V。
我想通过端口1输出直流偏置,因此它直接应用到我的DUT,我想知道7 V以上的偏置是否会对端口造成损坏。
由于内部产生的直流偏置确实高达40 V,我可以想象有一个内部偏置-T可以防止内部直流电源产生的直流电压到达端口1的前端。当然,我会
在尝试之前先验证一下!
谢谢,卡里姆

  We have an E5061B-3LF with the DC bias source option, and the DC output ranges from -40V to 40V.  This DC output can be tied to either a separate output OR to Port 1, which has a maximum allowable DC voltage of 7V.

I would like to output the DC bias through Port 1 so it is applied directly to my DUT, and am wondering if biases above 7 V will cause damage to the port.  Since the internally generated DC bias does go up to 40 V, I would imagine that there is an internal bias-T that prevents the DC voltage generated by the internal DC source from reaching the front-end of Port 1.  Of course, I would like verification of this before trying it out!

Thanks,
Karim

亲爱的kallidina,E5061B-3L5具有内部偏置三通电路,可在Port1输出直流偏置(-40V至40V)。
因此,您可以通过端口1输出直流偏置,可以直接应用于您的DUT。
对于7V的最大允许DC电压,用户注入外部DC偏压的情况。
由于E5061B采用50欧姆端接,因此在这种情况下,E5061B需要提供/吸收超过100mA的直流电流,即最大允许直流电流。
我还要注意,当用户设置E5061B的直流偏置时,外部直流偏置电压必须在“(E5061B的直流偏置设置)+ - 7V”范围内。
例如,如果E5061B直流偏置在端口1设置为+ 10V,端口1连接到驱动直流输出的稳压器输出端口,则其输出电压必须在+ 3V至+ 17V范围内(+ 5V至+ 15V为
建议将E5061B直流电流保持在100mAdc以内。

  Dear kallidina,

The E5061B-3L5 has internal bias tee circuit which can output DC bias (-40V to 40V) at Port1.
So, you can output DC bias through Port 1 that can be applied directly to your DUT.

As for the maximum allowable DC voltage of 7V, it is the case that user inject the external DC bias.
As the  E5061B is 50ohm terminated, in this case the E5061B need to source/sink more than 100mA DC current that is maximum allowable DC current.

I also would like to note that external DC bias voltage must be in the range of "(DC bias setting of the E5061B) +- 7V" when user set DC bias of the E5061B. For example, if the E5061B DC bias is set to +10V at Port1 and Port1 is connected to Voltage regulator output port that drive DC output, it's output voltage must be in the range of +3V to +17V(+5V to +15V is recommended to keep the E5061B DC current within 100mAdc).
