Agilent 1144A使用MSO-X 3034进行不正确的探头缩放

范围错误地为探针的缩放设置10：1。
运行“探针检查”会返回一条消息“...检测到探针为5：0按OK以应用此值”。
按OK而不是选择5：0（这对于此探针是正确的）似乎再次运行探针检查并返回消息“...检测到探针为2：0按OK以应用此值”。
再次按OK再次运行它并返回消息“...检测到探头为1：0按OK以应用此值”。
再次按OK会短暂闪烁一条我读得不够快的消息。
缩放比例保持为自动10：1。
系统固件2.35和2.12也观察到相同的行为。
唯一的解决方法是将探头的自动检测引脚绝缘，并手动将比例设置为5：0。
运行探测检查然后返回一个传递。
感谢tomasz。

   以下为原文

  The scope incorrectly sets 10:1 for the probe's scaling. Running "Probe Check" returns a message "...detected the probe to be 5:0 press OK to apply this value". Pressing OK instead of selecting 5:0 (which is correct for this probe) seems to run the probe check again and returns a message "...detected the probe to be 2:0 press OK to apply this value". Pressing OK again runs it yet again and returns a message "...detected the probe to be 1:0 press OK to apply this value". Pressing OK again briefly flashes a message which I can't read fast enough. The scaling remains on auto 10:1.

The same behaviour has been observed with the system firmware 2.35 and 2.12.

The only workaround is to insulate the probe's autodetect pin and manually setting the scaling to 5:0. Running the probe check then returns a pass.

Thanks

顺便说一句，1144A未列为3000X系列示波器的受支持探测器。
它在3000X系列示波器发布时几乎同时停产。
我很高兴您找到了解决方法。

BTW, The 1144A is not listed as a supported probe for the 3000X series of scopes. It was discontinued at just about the same time the 3000X series of scopes were released.

I'm happy that you found a workaround.
