怎么在N9010A上通过SCPI传输状态文件

1872 SCPI

问答对人有帮助，内容完整，我也想知道答案 0 我通过SCPI将状态文件从EXA传输到我的工作站，但是当我使用SMB使用smbclient进行传输时，文件与同一文件不匹配。当我复制文件并使用“调用状态”时，EXA表示它已损坏。我在perl中使用LAN接口。比较我可以看到的两个文件（至少）前16个中的6个字节是不同的。 Register001.state是使用smbclient获取的文件（我可以将其打包并且它可以工作），test.state是使用SCPI传输的。 test.state文件中缺少第一行中的4 0xff。我使用wireshark监控传输，EXA不发送数据。我正在使用SCPI命令“mmem：data？”D：\ User_My_Documents \ Instrument \ My Documents \ system \ Register001.state “ r n”来传输文件。有没有我做得不对的东西？ [roger @ lab-bunny-1吃] $ hexdump -C Register001.state \| head 00000000 00 01 00 00 00 ff ff ff ff 01 00 00 00 00 00 00 \| ................ \| 00000010 00 04 01 00 00 00 1c 53 79 73 74 65 6d 2e 43 6f \| .......

When I copy the file back and use 'recall state' the EXA says it is corrupted. I am using the LAN interface in perl. Comparing the two files I can see (at least) the 6 bytes in the first 16 are different. The Register001.state is the file fetched with smbclient (which I can put pack and it works), test.state was transferred using SCPI. The 4 0xff in the first line are missing in the test.state file. I used wireshark to monitor the transfer and the EXA is not sending the data. I am using the SCPI command "mmem:data? "D:\User_My_Documents\Instrument\My Documents\system\Register001.state"rn" to transfer the file. Is there something I am not doing correctly?

答案对人有帮助，有参考价值 0 谢谢你的回复。我已经删除了SCPI标题'＃'并且我读回了正确的字节数。我遇到的问题是状态文件中的0xff字节不会从EXA传输。我做了一个网络跟踪（使用wireshark），他们永远不会被发送。我相信0xff是telnet转义序列的起始字节。我连接到分析仪上的端口5023以与SCPI协议通信 - 这个端口是否会删除telnet转义序列？如果是这样，有更好的方法连接到SCPI协议接口？以上来自于谷歌翻译以下为原文 Thanks for the response. I already remove the SCPI header '#' and I read back the correct number of bytes. The problem I have is that the 0xff bytes in the state file do not get transmitted from the EXA. I did a network trace (using wireshark) and they are never sent. I believe that the 0xff is the start byte of a telnet escape sequence. I am connecting to port 5023 on the analyser to communicate with the SCPI protocol - would this port be removing the telnet escape sequences? and if so is there a better way to connect to the SCPI protocol interface?
