Agilent 33522B如何避免将元数据重置为默认值？

您好，使用Agilent 33522B时，我注意到使用SOUR：FUNC：ARB {}从易失性存储器中选择新波形时，请确保偏移和幅度设置恢复为默认值0V和100mV。
然后我可以设置所需的幅度和偏移量，但我的被测设备无法承受临时跳转到默认值。
我在GPIB上使用SOUR：DATA：ARB命令首先在易失性存储器中创建波形。
有没有办法指定元数据（幅度，偏移等）以及波形，以便在选择新波形时输出不会返回默认值？
对于较旧的33522A型号而言，这不是问题，在选择新波形时，当前元数据会保留。
从手册：“在固件版本1.12及之前，当从一个任意波形切换到另一个波形时，仪器没有更新波形元数据（采样率，电压范围和滤波器设置）。新的任意波形已采用波形的元数据
因此，设计为在一个电压范围，采样率和滤波器设置（在波形的元数据中指定）中播放的任意波形被更改为另一组元数据。在固件版本1.12之后，任意波形加载存在于中的任何元数据。
任意波形文件，以便它们像以前一样播放。“
我实际上更喜欢使用较旧的固件，除非这个问题有一个简单的解决方法。
是否有可能获得较旧版本的固件（1.12或更早版本）并在33522B型号上运行？
在此先感谢您的帮助。

  Hello,

When using the Agilent 33522B, I have noticed that using SOUR:FUNC:ARB {} to select a new waveform from volatile memory caues the offset and amplitude settings return to default values of 0V and 100mV.  I can then set the desired amplitude and offset, but my device under test cannot withstand the temporary jump to the default values.

I am using the SOUR:DATA:ARB command over GPIB to first create the waveforms in volatile memory.  Is there a way to specify the metadata (amplitude, offset, etc.) along with the waveform so that the output does not return to defaults when selecting a new waveform?

This was not an issue for older 33522A models, for which the current metadata was retained when selecting a new waveform.  From the manual:

"In firmware revisions 1.12 and before, the instrument did not update waveform metadata (sample rate, voltage
range, and filter setting) when switching from one arbitrary waveform to another. The new arbitrary waveform
adopted the metadata of the waveform already in memory. Therefore, an arbitrary waveform designed to play at one
voltage range, sample rate, and filter setting (as specified in the waveform’s metadata) was changed to another set of
metadata. After firmware revision 1.12, arbitrary waveforms load any metadata present in the arbitrary waveform file,
so that they play the way they previously played."

I would actually prefer using the older firmware, unless there is a simple workaround for this issue.  Would it be possible to obtain an older version of the firmware (1.12 or earlier) and run it on a model 33522B?

Thanks in advance for any help.
