我有一个N9923A,它有所有选项,所以包括010(时域分析)和305(电缆和天线分析仪)。
我的N9923A附带的纸质手册根本没有提到TDR选项,虽然我在网上找到了后来的PDF,并解释了如何使用它。
它说:*如何在变换设置表上进行设置* **按Meas Setup 4. * **然后变换* **然后变换设置。* **按下一页和上一页查看所有设置。*问题
是,如果按下键4,则没有“变换”菜单。
只有*设置*校准*输出功率*端口扩展,所以我看不到如何使用TDR。
查看系统/许可部分,它显示已安装010,因此应该可以使用此功能。
(有一些时域分析作为CAT选项的一部分,但这不是完整的TDR功能。)我没有TDR的一个可能原因是我已将固件从A.06.02降级到A5。
51,因为A.06.02不适用于Data Link。
我没有办法测试降级是否是原因,因为当我降级时,仪器没有备份A.06.02,A06.02已从安捷伦网站上撤下。
所以我无法将其升级到出厂版本。
有任何想法吗?

以下为原文
I've got an N9923A which has all op
tions, so includes 010 (time domain analysis) and 305 (Cable and Antenna Analyzer).
The paper manual which came with my N9923A does not mention the TDR option at all, although a later PDF I found on the web does, and explains how to use it. It says:
*How to make settings on the Transform settings table*
** Press Meas Setup 4.*
** Then Transform*
** Then Transform Settings.*
** Press Next Page and Previous Page to view all settings.*
The problem is, if I press key 4, there is no "Transform" menu. There is only
* Settings
* Calibration
* Output power
* Port extensions
so I can't see how to use the TDR. Looking on the System/Licensing section, it shows 010 is installed, so this functionality should be available. (There is some time-domain analysis as part of CAT option, but that is not the full TDR functionality.)
One possible reason I don't have the TDR, is the fact I have downgraded the firmware from A.06.02 to A5.51, as the A.06.02 does not work with Data Link. I've got no way to test if the downgrade is the cause, since the instrument did not make a backup of the A.06.02 when I downgraded, and A06.02 has been pulled from the Agilent web site. So I can't upgrade it to the version shipped.
Any ideas?
Dave
