想知道是否有其他人正在经历这种相同的行为。
我通过GPIB控制分析仪。 固件版本为14.06(最新)。 这就是我正在做的事情和我看到的事情。 * RST预设分析仪。 将中心频率设置为2MHz,跨度为50kHz,RBW为1kHz,并打开Marker Noise功能。 我将扫描设置为单一,打开平均,30次扫描,平均类型为视频。 我发送INIT; 开始平均,然后观察* OPC等待完成30次扫描。 从此时起,频谱分析仪需要3-10秒来处理每个GPIB事务。 在上述操作之后我想做的是进行标记最小搜索,然后关闭平均值,关闭标记噪声,然后重新开启连续扫描。 其中每个都通过GPIB作为单个命令完成到分析器,并在执行下一个命令之前执行3-10秒。 在我预设之前,分析仪将保持这种“缓慢”模式。 我在另一台有14.04固件的E4407B上尝试了这个,但没有看到这个问题。 但是,从14.04到14.06的固件更新包括对GPIB时序的改进,我发现GPIB命令随机出现语法问题,未终止的报头等问题与工作代码有关。 对14.06的更新已经纠正了这个问题,但现在我看到这个问题变慢了。 任何人都有类似的经历。 安捷伦有人可以解决这个问题吗 这是一个已知的问题? 会有固件修复吗? 任何解决方法(没有将30条迹线倾倒到PC并让它进行平均和标记噪声)? 感谢您的任何建议或帮助。 特洛伊。 以上来自于谷歌翻译 以下为原文 Wondering if anyone else is experiencing this same behavior. I am controlling the analyzer through GPIB. Firmware version is 14.06 (most current). Here is what I am doing and what I see happen. *RST to preset the analyzer. Set center freq to 2MHz, span to 50kHz, RBW to 1kHz, and turn on Marker Noise function. I set sweep to single, turn on averaging, 30 sweeps, average type is video. I send INIT; to start averaging, then watch *OPC waiting for completion of the 30 sweeps. From this point on, the spectrum analyzer takes 3-10 seconds to process each GPIB transaction. What I want to do after the above is do a marker min search, then turn off averaging, turn off marker noise, then turn continuous sweeping back on. Each of these is done as a single command via GPIB to the analyzer and is taking 3-10 seconds to execute before the next command executes. The analyzer will remain in this "sluggish" mode until I preset it. I have tried this on another E4407B that has 14.04 firmware and do not see this problem. However, the firmware update from 14.04 to 14.06 included improvements to GPIB timing and I was seeing issues with GPIB commands randomly having syntax problems, unterminated headers, etc with working code. The update to 14.06 has corrected that issue, but now I am seeing this slow down. Anyone have a similar experience. Can anyone from Agilent address this? Is this a known issue? Will there be a firmware fix for it? Any work-arounds (without dumping 30 traces to the PC and letting it do the averaging and marker noise)? Thanks for any suggestions or help. Troy. |

对不起,多个帖子。

嗨特洛伊 - 不用担心 - 论坛重复此刻比比皆是。 你用什么程序来控制E4407B; Agilent Vee,LabView,MatLab,? 您使用的是直接SCPI还是仪器驱动程序? 回复您认为有问题的区域的确切代码段,我们将尽力提供帮助。 语法错误和未终止的标头通常与固件无关,而与代码相关。 SCPI命令不会从一个版本的仪器固件更改为另一个版本。 可能发生的是SCPI对新仪器功能的增强。 让我们从关于标记噪声和平均的代码片段开始。 直到那时 - 以上来自于谷歌翻译 以下为原文 Hi Troy - No worries - forum duplications abound at the moment. What program are you using to control the E4407B; Agilent Vee, LabView, MatLab,? Are you using direct SCPI, or instrument drivers? Reply back with the exact code snippet where you think the problematic area is and we’ll try to help. Syntax errors and unterminated headers are usually not firmware related, rather code related. SCPI commands do not change from one version of instrument firmware to another. What can happen is SCPI enhancements for new instrument functionality. Let’s start with the code snip regarding marker noise and averaging. Until then - |
